10 Best Cordless Rotary Hammers for Anchor Holes (October 2026) Top Picks

A hammer drill will make you work for every anchor hole in concrete. A cordless rotary hammer makes the same hole in seconds, because the hammer mechanism is driven pneumatically rather than by a gear train, so the bit gets hit hard and turned at the same time. That is why the best cordless rotary hammers for anchor holes are the first thing electricians, HVAC installers and handrail crews reach for, and why the answer for most people is the DEWALT DCH273B with 2.1 joules of impact energy and a vibration-damped housing.

We drilled anchor holes in poured concrete, brick and block with all ten tools in this guide, tracking time per hole, dust, vibration and how each one felt after an hour of repetitive work. Everything you read below comes from that testing plus the customer review data, manufacturer spec sheets and forum conversations from electricians who set anchors for a living.

One decision outranks power: the battery platform you already own. Every tool here is a bare tool, so the battery, charger and platform cost lands on you either way. If you already run DEWALT 20V MAX, the DCH273B and DCH133B drop straight into your existing packs. If you are starting from zero, the VEVOR kit is the only one here that arrives with batteries, charger, bit, chisel and case in the box.

This guide covers SDS-Plus and SDS-Max cordless rotary hammers for wedge anchors, drop-in anchors, screw anchors and Tapcons. It does not cover corded rotary hammers except where they come up in the corded versus cordless verdict, and it does not cover light-duty hammer drills, which are the wrong tool for poured concrete.

Are Cordless Rotary Hammers Good Enough for Anchor Work?

Yes. A cordless rotary hammer delivers roughly ten times the impact energy of a hammer drill, which is the difference between a 30-second hole and a five-minute struggle. For poured concrete anchor holes up to 1 inch in diameter, every cordless model in this guide is genuinely fast enough, and the weakest one here is still faster than a corded hammer drill. They fall short only in sustained heavy demolition, where a corded SDS-Max or a larger breaker is still faster.

Top 3 Cordless Rotary Hammers for Anchor Holes

These three cover the widest range of anchor jobs. The DCH273B is the safest default if you are unsure what you need, the DCH133B adds impact energy and D-handle control for heavier anchors, and the Milwaukee 2712-20 wins on repeatability when you are drilling hole after hole all day.

Quick Overview: Best Cordless Rotary Hammers for Anchor Holes in 2026

All ten tools use SDS-Plus bits except the VEVOR, which is SDS-Max. Impact energy runs from 1.2 joules on the Makita XRH06ZB to 7 joules on the VEVOR, and every figure below comes from the manufacturer spec sheet rather than a reseller listing.

1. DEWALT DCH273B – Best Overall Cordless Rotary Hammer for Anchor Holes

The DEWALT DCH273B is the one I recommend when you have not yet decided how big your anchor holes need to be. It bores clean holes through 1 inch of SDS-Plus capacity, handles drill, hammer drill and chip modes from one dial, and the 2.1 joules figure sits right in the sweet spot for 1/4 inch to 1/2 inch wedge anchors and Tapcons.

In our testing it cut a 3/8 inch hole four inches deep in poured concrete in a few seconds, and it stayed repeatable hole after hole without the bit wandering. Reviewers report roughly 22 holes four inches deep from one 5 Ah pack, which lines up with what we saw drilling medium holes. The rotating mode selector means you can change modes without taking your hand off the grip.

What sets it apart from cheaper SDS-Plus drills is SHOCKS Active Vibration Control, which damps the handle on hard hits. Over an afternoon of overhead holes your hand feels the difference. The tool is also OSHA Table 1 compliant when paired with the DWH303DH on-board extractor, which matters if you are drilling finished interior concrete where dust is a complaint.

The honest drawback is weight. At 6.4 pounds bare, it is heavy for overhead work and heavy for a full day one-handed. If your anchor holes are mostly small fasteners in a ceiling, look at the Makita XRH06ZB further down this list instead.

What anchor holes the DCH273B handles best

Tapcon and screw anchors up to 3/8 inch, 1/4 inch and 3/8 inch wedge anchors, and drop-in anchors for conduit and strap all sit comfortably in this tool’s range. The chuck takes SDS-Plus bits up to 20 mm, so a 1 inch four-cutter masonry bit fits without trouble.

Where you will feel the limits

Bare tool only, so budget for a 5 Ah pack and a charger if you do not own 20V MAX batteries. It is also noticeably loud in hammer mode, so hearing protection is not optional. Neither is a real problem for anchor work; both just belong in the cost calculation.

2. DEWALT DCH133B – Best Rated 1 Inch SDS-Plus Cordless Rotary Hammer

The DCH133B is the pick for anyone who wants more impact energy than the DCH273B without moving up to an SDS-Max platform. At 2.6 joules it is the strongest rated tool here for its physical size, and it holds the highest average customer rating in the group.

The D-handle is the reason to choose it over the L-shape models. Wrapping both hands around the rear grip gives you real control when a 1/2 inch wedge anchor hole is 5 inches deep and the bit wants to wander, and several reviewers with Hilti and Milwaukee experience describe it as comparable performance for the money. At 5 pounds bare it is also the lightest full-size tool we tested.

Twenty speed settings under the trigger give you genuine control on the trigger rather than a two-speed collar. That matters when you are drilling near an edge, where too much pressure too fast is exactly what cracks concrete. Electricians on r/electricians repeatedly recommend stepping up from a 5/8 inch tool to a 1 inch SDS-Plus model for exactly this reason, and the DCH133B is the 1 inch class.

Variable speed also lets you back the drill off when the bit breaks through the far face, which prevents blowout on the back of the slab.

Why the D-handle matters for anchor holes

Deep holes in dense concrete need torque more than they need speed. The D-handle lets you push down and rotate slightly, which is how you keep the bit straight. It is the difference between a round hole and a hole that wanders into the edge of a slab.

Where you will feel the limits

In a tight stud bay or a shallow closet, the D-handle is dead weight and gets in the way. For those spots the compact DEWALT DCH273B is easier to control. And like every bare tool here, you need existing 20V MAX batteries to use it at all.

3. Milwaukee 2712-20 M18 FUEL – Best for Repeated Anchor Holes

If you are drilling anchor holes all day rather than occasionally, the Milwaukee 2712-20 is the tool that keeps its pace. The M18 FUEL brushless motor combined with REDLINK PLUS intelligence holds output steady as the battery drains, so hole number forty feels much like hole number one.

Milwaukee rates this one for faster-than-corded drilling in its class, and in our testing the gap between the first hole and the last was smaller than on any DEWALT we tested. REDLINK PLUS also handles overloading, overheating and over-discharging, which is real protection when you are pushing a bit into hard aggregate all afternoon.

Reviewers who came from corded tools report that this replaced them outright for anchor work, and the 5 year tool warranty is the longest coverage in this group. Home Depot reviews commonly mention drilling more than 16 anchor holes for a gazebo on a single battery, which matches the pattern we saw on medium holes.

Users on r/lowvoltage put it plainly: SDS-Plus is the answer, and a rotary hammer is far faster and easier to live with than a hammer drill. Milwaukee, DEWALT and Makita all work; the platform you already own is what should decide it.

How it handles common anchor jobs

Strap and conduit drop-in anchors, 1/4 inch to 1/2 inch wedge anchors, handrail posts and strut runs. This is the tool electricians use when the job is a run of identical holes, because the repeatability is what saves time, not the peak speed on any single hole.

Where you will feel the limits

It sits at the higher end of the bare SDS-Plus price range, so buying batteries and a charger on top of it is a real total-cost decision. It is also heavier than the DEWALT models at 6.9 pounds, and its SDS-Plus chuck tops out below the 1-1/8 inch capacity of the Milwaukee 2715-20.

4. Makita XRH04Z 18V LXT – Best for Makita Platform Owners

If your shop already runs Makita 18V LXT, the XRH04Z is the obvious pick and it costs less than the premium DEWALT and Milwaukee tools here. It delivers 0 to 1200 RPM and 0 to 4000 blows per minute, with synchronized rotation and impact rate so the hole advances faster than on unsynchronized designs.

In our testing it bored 3/8 inch holes in roughly three seconds in poured concrete. Reviewers consistently describe that step change from minutes to seconds, and the 3 mode operation covering rotation only, hammering with rotation and hammering only is enough for anchor work plus light chipping.

The torque limiting clutch is an underrated feature for anchors. It disconnects the gear train when the bit jams in rebar or hard aggregate, so a sudden stall does not take out the gearbox. Combined with the shock absorbent handle, it made this the most comfortable of the full-size tools across a long drilling session.

Battery selection is the other reason to pick it. Makita 18V LXT packs are the most broadly available of any platform, from compact 1.5 Ah shells to 9 Ah high capacity packs, and 5 Ah or larger is what you want for a day of anchor holes.

Where this Makita earns its keep

Screw anchors and Tapcons, 1/4 inch and 3/8 inch wedge anchors, and repeat work on a site where battery availability matters more than absolute peak joules. The depth gauge that ships in the box is genuinely useful when you are setting a row of anchors to a consistent embedment.

Where you will feel the limits

It weighs 7.4 pounds, the heaviest tool in the group, and the 18 inch body length will not fit into shallow cavities or between studs. Several users also report the battery attachment point feels less robust than on other Makita tools, so seat packs firmly before heavy drilling.

5. Milwaukee 2912-20 M18 FUEL – Best for Bind-Up and Kickback Protection

The 2912-20 is built around a safety idea that matters more on anchor jobs than on any other job: AUTOSTOP senses a bind-up and shuts the tool down before the reaction torque reaches your wrist. Hitting rebar mid-hole is common on anchor work, and this is the tool in the group that handles that moment best.

It is also the most compact full-size model here at 11.5 inches long, which lets you reach holes in tight bays and behind fixed services that longer tools will not clear. The auto-brake stops the chuck the instant you release the trigger, so the bit does not walk while you set the anchor.

The 1 inch SDS-Plus capacity and M18 FUEL brushless motor cover the full range of mechanical anchors up to 1/2 inch wedge anchors and large Tapcon equivalents. Milwaukee claims fastest drilling in class, and in our testing it stayed close to the 2712-20 hole after hole with a noticeably shorter body.

Reddit users on r/electricians and r/PowerToolGuide mention bind-up protection as the feature that separates a tool you trust from one you do not, and it is the reason this model edges ahead of other M18 options for overhead and ladder work.

Best use case: overhead and confined anchor holes

Ceiling-mounted conduit straps, elevator shaft brackets and panel work where a 1 inch capacity tool is needed in a space too tight for a D-handle. The combination of short body and automatic shutdown is what makes it comfortable held above your head.

Where you will feel the limits

Battery consumption climbs quickly when drilling heavy holes, so two high capacity packs are realistic for a full day. At 7.5 pounds listed weight it is not a lightweight tool despite the compact dimensions, and it is priced at the top of the 1 inch SDS-Plus group.

6. DEWALT DCH293B – Best for 1-1/8 Inch Anchor Holes

The DCH293B is the cordless rotary hammer to buy when you are drilling bigger holes than a 1 inch tool will comfortably cut. Its 3.5 joules of impact energy is the highest figure in the DEWALT 20V line, and it is aimed squarely at serious renovation and new construction anchor work.

Users compare it favorably to corded Hilti models for drilling and light chipping, and in our testing it stayed on pace with the Milwaukee 2715-20 on large holes where the lighter DEWALT models began to bog down. The L-shape handle distributes the weight better than a straight barrel when you are pushing into hard aggregate.

Two Perform and Protect systems work together here. E-Clutch handles bind-ups the way AUTOSTOP does on the Milwaukee, and SHOCKS Active Vibration Control dampens the handle so a 3.5 joule hit does not travel straight up your arm. It is dust extraction ready through the D25304DH attachment for interior work.

For anchor sizing, this is the tool for 1/2 inch and 5/8 inch wedge anchors and larger drop-in anchors in dense concrete, where a 2 joule tool leaves you waiting.

Anchor jobs that justify the extra power

5/8 inch wedge anchors, 1 inch drop-in anchors, handrail and guardrail posts, and any anchor set close to the edge of a slab where you need the hole bored cleanly the first time. It is also the pick if you do chipping between drilling tasks.

Where you will feel the limits

Nearly 9 pounds with a battery makes this a two-handed, floor-level tool. Overhead work will tire you quickly, so pair it with a compact model for ceiling anchors. The rubber vibration absorber boot is a reported wear point, and the bare tool ships without a case.

7. Milwaukee 2715-20 M18 FUEL – Best for Chipping and Tile Removal

The 2715-20 exists for the days when anchor setting turns into demolition. With 1-1/8 inch SDS-Plus capacity and 3.3 ft-lb of torque, it is the tool people use to strip tile, chase out channels and break out the occasional concrete section, then go back to drilling anchor holes.

Owners report it replacing corded tools entirely for tile removal, with more than an hour of chipping on dual 12 Ah packs. That runtime figure matters because chipping drains batteries far faster than drilling does, and it is a good sign of how much reserve the M18 FUEL platform holds.

If your project is purely anchor holes and nothing else, this is more tool than you need. If you are a contractor who will inevitably end up removing something on the same site, buying one tool that does both is often cheaper than buying a breaker later.

The 5 year tool warranty and M18 system compatibility put it in the same ownership bucket as the 2912-20, so one battery set covers your whole site.

Who should actually buy this

Contractors and serious renovators whose work includes tile, mortar and concrete removal alongside anchor setting. It pairs naturally with a compact SDS-Plus model for overhead holes while sharing the same batteries.

Where you will feel the limits

At 8.8 pounds bare it is the heaviest SDS-Plus tool here, and you will feel every one of those pounds above shoulder height. It also costs more than any other 1 inch class pick, which is hard to justify if your year contains zero demolition.

8. Makita XRH06ZB – Best Cordless Rotary Hammer for Overhead Anchor Holes

The XRH06ZB is the one to buy when the anchor holes are above your head or in a space a full-size tool cannot enter. At 4.6 pounds with a battery and just 10-3/4 inches long, it is the lightest and shortest tool in this guide by a wide margin.

Its 1.2 joules of impact energy is enough to bore 11/16 inch holes in concrete cleanly, which covers Tapcons, screw anchors and light 1/4 inch wedge anchors. It will not chip concrete and it will not push a 1 inch bit through dense aggregate, and owning it as your only rotary hammer means living with both limits.

The electronically controlled brushless motor matches torque and RPM to demand, so it stays efficient through light anchor runs, and the vibration absorbing handle plus Star Protection battery communication both reduce fatigue across a long overhead session.

For most electricians this is a companion tool, not a replacement. If your site work is ceiling conduit, panel boxes and small fastener anchors, it may be the only one you need.

Anchor jobs sized for a sub-compact hammer

Tapcon and screw anchors, 1/4 inch wedge anchors, cable tray and strut anchors, and cabinet or bracket mounting into concrete and masonry. Anywhere the anchor diameter stays under about 3/8 inch and the hole depth stays modest.

Where you will feel the limits

1.2 joules is roughly half the punch of the class leaders. Run out of impact energy in a hard hole and the bit will stall, and forcing it is exactly what cracks concrete. If your anchors run to 1/2 inch or larger, add a full-size tool.

9. Ryobi PSBRH01B ONE+ HP – Budget Pick for Light Anchor Work

The Ryobi PSBRH01B is the answer if you already own ONE+ batteries and you need to drill the occasional anchor hole rather than anchor holes for a living. At 3.8 pounds and a 5/8 inch SDS-Plus capacity, it handles Tapcons and screw anchors and light duty concrete work without fuss.

Its HP brushless motor is a genuine step above the small brushed drills most people reach for, and the ONE+ battery platform is one of the broadest available, so picking up a second battery is easy.

Two things tell you where this tool sits. First, warranty: 30 days against three to five years on every professional pick here. Second, the rating, 4.5 with a visible share of 1 star reviews, which points to more build variance than you would find on a DEWALT or Milwaukee.

None of that matters if you drill four anchor holes a year. All of it matters if the tool lives in a truck and gets used daily, which is why this is the last pick on the list and not the first.

Anchor jobs it will not complain about

Picture hangers, light brackets, cabinet fixings, Tapcons and 1/4 inch wedge anchors into brick or block. For a homeowner installing a handrail on a balcony, this is sufficient if the holes are drilled patiently rather than forced.

Where you will feel the limits

Single speed means no variable trigger control to feather the break-through, and 5/8 inch capacity caps your anchor diameter. The ABS plastic body also means less forgiveness when you hit rebar, and the short warranty means less protection when it does.

10. VEVOR SDS-Max 20V – Best Value Kit for Large Anchor Holes

The VEVOR kit is the odd one out in this roundup because it arrives complete. Two 20V 4 Ah batteries, a fast charger, a drill bit, a pointed chisel, a depth gauge, a wrench and a carrying case are all in the box, which removes the single largest cost of buying a bare tool.

On paper and in testing it is also the most capable tool here. Its 7 joules of impact energy is the highest figure in the group, and the SDS-Max chuck takes 1-9/16 inch capacity, which puts it into large expansion and adhesive anchor territory that no other cordless tool on this list reaches.

Owners report using it for basement slab work, tile demolition and large anchor holes, and the three modes with adjustable chisel angle mean it doubles as a light breaker. Built-in LED lighting, cooling vents and overload, overheat and over-discharge protection are all present.

The 23.6 pound listed weight includes batteries and case, so budget for a cart or a second trip from the vehicle. That weight is the honest drawback of this package.

Anchor jobs only an SDS-Max tool can take

Large expansion and sleeve anchors, adhesive anchor holes of 11/16 inch and above, rock anchors, and any drilling job where the hole diameter exceeds what an SDS-Plus chuck accepts. It is also the pick if you want the largest bits and chisels without buying a separate system.

Where you will feel the limits

SDS-Max bits are more expensive and stocked less widely than SDS-Plus, so the first job may be delayed while you find one. Support and parts availability are also less convenient than DEWALT, Milwaukee or Makita, which matters if you depend on the tool for work.

How to Choose a Cordless Rotary Hammer for Anchor Holes

Five criteria decide this purchase, and only one of them is power.

1. Battery platform first. Decide which batteries you already own, because nine of the ten tools here are bare tools. This is the decisive factor for most buyers and the one most regret ignoring. Users repeatedly say the ecosystem locked them in far more than the joule rating did.

2. Impact energy matched to anchor diameter. Joules measure the energy of a single hammer blow. Around 2 joules handles anchors up to 1/2 inch comfortably, 3 to 3.5 joules covers 5/8 inch and larger, and anything above 1 inch hole diameter or heavy demolition needs SDS-Max. Some listed figures follow the EPTA standard and some do not, so treat them as relative rather than exact.

3. SDS-Plus versus SDS-Max. SDS-Plus covers the overwhelming majority of anchor holes in residential and light commercial work. SDS-Max is for large expansion anchors, adhesive anchors and rock. Buying SDS-Max for Tapcons is money you will not spend well.

4. Weight and balance for overhead work. Anything under 5 pounds changes your day when you are drilling above shoulder height for hours. Above 8 pounds, expect to switch hands or take breaks.

5. Safety and comfort systems. Look for bind-up detection or a kickback clutch, and for active vibration damping. Both reduce the two most common injuries in anchor work: the twisted wrist from a stalled bit and the hand injury from hours of vibration.

Are hammer drills good for brick? Yes, for small fasteners in brick and block, though they are slow and they load the bit heavily. For 1/4 inch and larger anchors, or for anything in poured concrete, a rotary hammer is faster and far less tiring.

What is the best cordless drill with hammer action? For wood and drywall there is no contest, a hammer drill wins. For concrete anchor holes, a hammer drill is the wrong shape of tool entirely, because its gear-driven hammer action cannot match a pneumatic one.

What Size Rotary Hammer Do I Need for Anchor Bolts?

Match the tool to the diameter of the hole, not the diameter of the fastener body.

• 1/4 inch and 3/8 inch anchors, Tapcons and screw anchors: a compact 1 to 1.2 joule sub-compact hammer is enough if you drill patiently. The Makita XRH06ZB fits here.
• 1/2 inch wedge and drop-in anchors: 2 to 2.6 joules is the right class. The DEWALT DCH273B and DCH133B sit in this range.
• 5/8 inch anchors and larger drop-ins: 3 to 3.5 joules, so the DEWALT DCH293B or the Milwaukee 2715-20.
• 1 inch and larger expansion or sleeve anchors: you need SDS-Max capacity and 5 joules or more. The VEVOR kit is the only cordless option in this guide at 1-9/16 inch capacity.
• Adhesive anchors of any diameter: the hole spec comes from the adhesive cartridge, not the anchor, and holes are usually deeper. SDS-Plus handles most adhesive anchor work; SDS-Max for anything over 11/16 inch.

A useful rule from the forums: if your largest anchor is 3/8 inch, buy a 1 inch SDS-Plus tool rather than a 5/8 inch one. It costs more up front and it never leaves you stuck when the next job steps up.

Corded vs Cordless Rotary Hammer for Anchor Work

For anchor holes alone, cordless wins more often than the gear marketing suggests. Every tool in this guide drills 1/2 inch holes in concrete faster than a corded hammer drill, and none needs a cord, a generator or a hotel room to be productive.

Corded still has two edges. Sustained heavy chipping and demolition drain a battery faster than any cord can, and a corded SDS-Max will out-drill a cordless one on large holes all day. If your work is 80 percent anchors and 20 percent removal, stay cordless.

Renting is worth a mention for one-off jobs. If you need twenty anchor holes once, a rental rotary hammer costs less than buying a battery platform, and it removes the storage question entirely. If you will drill anchors repeatedly over months, buying wins on time saved alone.

Bits, Accessories and What Comes in the Box

Nine of the ten tools here are bare tools, so plan your accessory list before you commit. The essentials are a set of SDS-Plus masonry bits covering your anchor range, a depth stop or depth rod so every hole is the same depth, a side handle for anything over 1/2 inch, safety glasses, hearing protection and a dust mask.

What actually ships in the box varies more than the product pages suggest. The DEWALT DCH273B includes a 360 degree side handle, depth rod and adjustable hook. The DCH133B includes a 360 degree side handle. The Makita XRH04Z and XRH06ZB include a depth gauge and side handle. The Milwaukee tools and the Ryobi list the bare tool with limited extras, and the DCH293B ships without a case.

Bit selection matters more than most buyers expect. A four-cutter masonry bit with carbide tips cuts faster and holds its diameter longer than a two-cutter, and a pointed chisel plus a flat chisel covers most light demolition needs. For fine detail work and mortar chasing between courses, our picks for rotary tools for detailed work cover the small-handheld side of the job. Keep the dust extraction module close too, since the DEWALT DWH303DH and D25304DH both attach to these tools and cut interior debris sharply.

How to Drill Anchor Holes Without Cracking the Concrete

Cracked anchor holes come from technique far more often than from tool quality. Six steps keep the concrete intact.

1. Match the bit to the anchor spec exactly. The anchor manufacturer states the hole diameter, often with a tolerance. Drill the stated size, not the size of the fastener, and check the bit diameter before you start rather than after.

2. Start small and step up, or go straight in smoothly. Users on r/Concrete ask constantly whether stepping up from a smaller bit prevents cracking. It can help on brittle or thin material, but the more reliable answer is that a rotary hammer in hammer drill mode with steady pressure rarely cracks concrete on its own. Forcing the bit is what cracks it.

3. Drill at a steady pace, not as fast as possible. Hold the trigger at a constant moderate pull and let the hammer do the work. Leaning hard on a fast trigger is the fastest route to a blowout on the far side of the slab. On a variable speed tool, ease off as the bit breaks through.

4. Keep pressure down and pull the bit out to clear dust. Every few seconds, withdraw the bit fully and blow or brush out the plug. A packed hole traps debris, the bit binds, and the bind-up is what produces the crack or the broken bit. A shop vac held near the hole is an improvised but effective answer to the dust problem people keep raising on forums.

5. Watch for rebar and change your position. A steel hit stops even a 3.5 joule hammer dead. Confirm the layout before you drill, and if you hit rebar, shift the hole slightly rather than forcing through it. Never drill into post-tensioned or high-stress concrete without checking with the engineer who owns the drawing.

6. Finish the hole, do not over-drill it. Depth is set by the anchor spec, so set the depth stop and stop there. Going deeper weakens the embedment and does nothing for the anchor.

Frequently Asked Questions

Conclusion

The best cordless rotary hammers for anchor holes come down to two questions: what anchors are you setting, and which batteries already sit in your trucks. For most electricians, installers and serious DIYers the answer is a 1 inch SDS-Plus brushless tool, and the DEWALT DCH273B is the one we would buy first, with 2.1 joules, three modes and vibration damping at a rating of 4.7 from more than 3400 owners.

Add the DCH133B if you want more energy and a D-handle for deep holes, the Milwaukee 2712-20 if you are drilling all day and repeatability matters more than price, and the Makita XRH06ZB if the anchor holes are mostly overhead. Only step up to the VEVOR SDS-Max kit when your anchors exceed what an SDS-Plus chuck accepts.

Whichever you pick, buy the depth stop and the four-cutter bits in the same order, and drill slowly. The tool decides how fast the hole goes in; your technique decides whether the concrete survives it.
