Can an Impact Wrench Be Used as a Drill?

Yes, conditionally: a suitable adapter can connect a drill bit to the square-drive anvil. Physical fit is only the first check; the wrench, adapter, and bit must permit the intended use.

Under light resistance, an impact wrench can rotate without hammering. As resistance rises, its mechanism delivers rotational blows that help loosen or tighten fasteners.

That change matters during drilling. A bit can catch, the tool can react suddenly, and the impacts can make a clean start or careful finish harder to manage.

For a closer explanation of the mechanism, read how a cordless impact wrench works. More fastening torque doesn't automatically make a wrench a better drilling tool.

What adapter do you need for an impact wrench?

You need a square-drive-to-chuck or bit-holder adapter expressly rated for impact-wrench use. Match the wrench's drive size, the bit's shank, and the permitted application before attaching anything.

A chuck grips a range of bit shanks within its stated capacity. A hex bit holder accepts the matching hex shank, so an ordinary round-shank drill bit won't fit that holder directly.

Check these points before choosing an adapter:

Drive fit: the adapter must match the wrench's square drive.
Bit fit: the chuck or holder must accept and retain your bit.
Operating limits: speed, torque, and impact limits must suit the wrench.
Allowed use: the instructions must cover your material and drilling task.

An accessory described as suitable for an impact driver is not automatically suitable for an impact wrench. Those tools use different fittings and can place different loads on accessories.

Avoid stacking reducers, extensions, and multiple holders just to make a connection. Each joint adds length and another place for movement, which can make the bit harder to guide.

When does impact action make drilling harder?

Impact action is a poor match for holes that need a clean edge, exact position, or consistent depth. A regular drill supplies steady rotation without the wrench's rotational hammering.

For wood, use a bit made for the hole you need and support the exit side with scrap material. That backing helps reduce splintering as the bit breaks through.

For metal, starting accurately and following the bit's speed guidance matter more than peak torque. Clamp thin sheet securely so a catching bit cannot spin the workpiece.

An impact wrench is also different from a hammer drill. Its blows act around the rotation of the anvil, rather than along the bit's axis, so an adapter doesn't make it a masonry-drilling tool.

For holes close to a finished edge, hardware mounting points, or matching holes through several parts, choose a drill from the start. Correcting a misplaced hole usually takes longer than changing tools.

Which impact wrench suits your actual fastener work?

Choose among these wrenches for socket work, not as a shortcut to buying a drill. Their useful differences are drive size, access, controls, and battery system.

Milwaukee M18 Compact: for controlled socket work

The Milwaukee M18 FUEL Compact suits buyers who want a 3/8-inch wrench with several fastening controls, especially those already using M18 batteries. It is a bare tool without a battery or charger.

Its 4-Mode DRIVE CONTROL provides preset speed and impact levels. Auto shut-off limits torque to no more than 20 ft-lbs for hand-tight fastening applications, while bolt removal control reduces speed after a bolt loosens.

Those modes help with fasteners; they don't act as a drill clutch or depth stop. Skip this choice if your main task is boring holes or you need a different drive size for existing sockets.

Bosch GDS18V-350N: for existing 1/2-inch sockets

The Bosch suits buyers with 1/2-inch impact sockets who want a compact mid-torque wrench. Its 3 speed settings let you select the operating range for the fastening job.

Bosch specifies 410 ft-lbs of breakaway torque and 250 ft-lbs of fastening torque. These describe different jobs, so don't treat the larger figure as a drilling capability.

Auto Bolt Release stops rotation under no load during removal. Buyers in the compatible Bosch 18V or AMPShare system have a practical reason to consider it; batteries and accessories are separate.

Skip it if drilling is the main goal or your work calls for a smaller socket drive. Adding an adapter also extends its 5.2-inch head, which matters inside a cabinet or crowded assembly.

Milwaukee M12 Stubby: for M12 socket-tool buyers

The Milwaukee M12 FUEL Stubby suits buyers who want a 3/8-inch socket tool on the M12 platform. It measures 4.8 inches long and comes as a bare tool.

Milwaukee claims up to 550 ft-lbs of nut-busting torque. That figure concerns loosening fasteners and doesn't establish clean-hole performance, speed suitability, or approval for a chuck adapter.

Consider it when socket access and your battery platform drive the decision. Skip it if you're choosing purely by torque to replace a drill, and remember that M12 and M18 use different batteries.

If your sockets don't settle the drive choice, what size impact wrench you need explains the tradeoffs. Our cordless impact wrench buying guide covers the wider tool category.

Should you use a drill, impact driver, or impact wrench?

Choose a drill for holes, an impact driver for many screw-driving jobs, and an impact wrench for socket-driven fasteners. Start with the job you repeat most often.

Your main job	Tool to choose	Why it fits
Furniture holes, pilot holes, and hardware mounting	Drill	Chuck accepts suitable drill bits and rotation stays steady
Repeated screw driving into wood	Impact driver	Hex collet accepts matching driver bits
Removing or tightening nuts and bolts	Impact wrench	Square drive accepts matching sockets
Mixed home repair work	Drill first, then a dedicated fastening tool	Hole making and heavy fastening need different controls

A drill's adjustable clutch generally serves screw driving, while its drilling mode allows hole making. Select the mode and speed range described in that drill's instructions.

For screw-focused projects, our guide to impact wrench vs impact driver explains their fittings and common uses. Don't choose a wrench simply because its torque figure is larger.

Can an impact wrench replace a drill for occasional holes?

Only as an approved occasional setup, when accuracy and finish demands are modest. Owning the wrench already doesn't establish that the adapter combination is suitable.

Check the total cost and length of the required accessories before buying them. If you expect more hole-making work, a separate drill is the more useful addition.

How do you set up and care for a drilling adapter?

Disconnect the power source before fitting or adjusting the adapter and bit. Follow the retention instructions, then check that every connection is secure before restoring power.

Clamp the work to a stable surface and leave clearance beneath the intended hole. Keep the bit's path clear of clamps, hidden wires, pipes, and the bench itself.

Wear eye protection, secure loose hair and clothing, and keep hands away from rotating parts. Use the grip and support method required by the tool instructions.

Begin only within the accessory's permitted operating range. Stop immediately if the bit slips, the adapter loosens, the setup wobbles, or the bit binds.

After use, disconnect power and clear chips with a brush once the parts have stopped and cooled. Inspect the adapter's drive connection, retention parts, and bit grip for wear or damage.

Replace damaged accessories rather than tightening them harder or forcing them back into service. Keep chips out of the chuck and follow its care instructions.

Which mistakes should you avoid?

Don't confuse a connection that fits with equipment approved for the job. That mistake can turn a simple hole into a damaged bit, loose adapter, or uncontrolled workpiece.

Using a removal mode for drilling: bolt-release features are designed around fastener removal.
Holding small parts by hand: a catching bit can pull the material around.
Pushing through a stall: stop, disconnect power, and resolve the bind.
Ignoring attachment length: a short wrench can become a long assembly with a chuck and bit.
Choosing by breakaway torque: drilling also depends on bit type, speed, alignment, and material.

For a wrench bought mainly for automotive or assembly work, how to choose an impact wrench helps you match torque, anvil, and battery needs.

Should you buy an impact wrench to use as a drill?

Buy a drill when holes are the main job. An impact wrench can be used as a drill only with a permitted adapter setup, making that a secondary option rather than a reason to choose one.

Pick the M18 Compact for its fastening controls, the Bosch for compact 1/2-inch socket work, or the M12 Stubby when the M12 platform fits your needs. Choose the battery system and sockets around the work you actually do.

If screw driving is your next priority, compare an impact wrench with an impact driver before adding another tool.

Frequently asked questions

Can an impact wrench drill into wood?

An impact wrench can turn a wood-drilling bit through a compatible adapter, provided the equipment instructions allow that use. A regular drill gives you better control over the start and depth of the hole.

Clamp the wood, support the exit side, and choose a bit made for the material.

Can you put a drill bit in an impact wrench?

You usually need an adapter because a drill bit cannot attach directly to a square-drive anvil. Choose a chuck or bit holder expressly rated for impact-wrench use, with the correct drive size and shank fit.

The wrench, adapter, and bit must also permit the intended drilling task.

Is an impact wrench the same as an impact driver?

No. An impact wrench uses a square-drive anvil for sockets, while an impact driver usually uses a quick-change hex collet for driver bits.

Both deliver rotational impacts, but their fittings and common jobs differ.

Compare an impact wrench and impact driver before choosing a tool for screws or bolts.

Can an impact wrench drill into metal?

A regular drill is the better choice for metal because steady rotation helps you start and control the hole. Only consider a wrench if all equipment instructions allow the task.

Clamp the work, follow the bit's speed guidance, and stop if it binds instead of forcing it through.
