Think an Impact Driver Can Replace a Drill? Read This First

If we own an impact driver, this question shows up sooner or later.

We’re standing there, ready to make a hole, and we wonder:
Do we really need a drill, or can we just use the impact driver?

It’s a fair question. Impact drivers are powerful, compact, and already in our hands. Switching tools can feel unnecessary. Sometimes it works out fine. Other times… not so much.

Let’s clear up when an impact driver can replace a drill, when it can’t, and how to avoid the most common mistakes.

Yes, we can use an impact driver to drill holes.

But.

It depends heavily on:

• The material

• The size of the hole

• The type of drill bit

• The level of precision we need

An impact driver is not a perfect substitute for a drill. It’s more like a backup option for certain situations.

This is always the first decision. Different materials require different bit designs.

Before deciding, we need to understand how these tools behave.

A drill:

• Spins smoothly

• Is designed for controlled, consistent rotation

• Usually has adjustable clutch settings

An impact driver:

• Spins and adds bursts of rotational force

• Is optimized for driving screws and bolts

• Delivers more torque but less finesse

Power vs control.
That’s the trade-off.

There are situations where an impact driver performs surprisingly well.

Small Holes in Wood

For light-duty drilling in softwood, it usually works without drama.

Good examples:

• Pilot holes

• Small hardware

• Basic DIY tasks

If precision isn’t critical, we’re usually fine.

Rough Construction Work

If we’re drilling holes where appearance doesn’t matter much, the extra torque isn’t a problem.

Here’s where things get tricky.

Larger Holes

Impact action can:

• Make the bit wander

• Create rough edges

• Reduce accuracy

Metal

Metal usually prefers:

• Smooth rotation

• Steady pressure

• Controlled speed

The hammering action of an impact driver can make the process harder.

Precision Work

If alignment matters—like hinges or hardware—the extra force can work against us.

Impact drivers typically use hex-shank bits.

Regular round-shank drill bits often require an adapter. While adapters exist, they add:

• Extra movement

• Less stability

• More chances for wobble

More wobble = less accurate holes.

Impact drivers are fast and powerful. That’s great for screws.

For drilling, though, too much torque can:

• Grab suddenly

• Pull the tool forward

• Make it harder to stay straight

This surprises many beginners.

Assuming More Power Means Better Results

It often means rougher results.

Skipping the Pilot Hole

Impact drivers benefit from guidance even more than drills.

Using Dull Bits

Dull bits plus impact force equals frustration.

• Stick to small holes

• Use sharp bits

• Hold the tool firmly

• Start slowly

• Expect less precision

• Test on scrap material first

These steps improve success dramatically.

We should reach for a drill when:

• Hole size is large

• Material is hard

• Precision matters

• We want a clean finish

Drills are built for this job. They make it easier.

Because they’re convenient.

They’re often:

• Already in hand

• Lightweight

• Powerful

• Great at driving fasteners

And sometimes that convenience wins.

If we feel unsure whether the impact driver will behave predictably, switching to a drill is usually the smarter move.

Comfort leads to control.
Control leads to better results.

Can You Use an Impact Driver as a Drill?

• Yes, for small and simple holes

• Works best in wood

• Not ideal for metal or precision tasks

• Hex-shank bits are preferred

• Expect less control

• Use sharp bits and start slowly

• Switch to a drill when accuracy matters

An impact driver can absolutely drill—but knowing its limits helps us avoid frustration and get better outcomes in our projects.
