How to Use a Cordless Screwdriver as a Drill: Complete Guide

Yes, a cordless screwdriver can drill small holes when it has a chuck or a compatible bit holder, adjustable speed, and enough torque for the material. It is best for light-duty drilling in wood, plastic, drywall, and thin sheet metal—not masonry or demanding construction work.

The first clue is often the sound: a driver that handles screws smoothly may slow, whine, or stop when a drill bit meets resistance. That change usually means the tool is reaching its torque limit, the bit is dull, the speed is wrong, or the material needs a more powerful drill. Protecting the hole, the bit, and the screwdriver starts with recognizing that difference before forcing the trigger.

This guide explains how to check compatibility, choose the right bit, set speed and torque, drill cleanly, and avoid overheating or damaging the tool. It also covers the situations where a regular cordless drill or hammer drill is the safer choice, so you can decide whether your screwdriver is suitable for the job.

Can a Cordless Screwdriver Really Drill?

A cordless screwdriver is designed primarily to drive screws, but many models can also make small pilot holes. The key distinction is the tool’s chuck or bit interface. A screwdriver with a hex bit holder may accept drill bits made for impact drivers or quick-change drivers, while a model with a three-jaw chuck can grip standard round-shank bits.

Some compact electric screwdrivers have limited torque, a low top speed, or no clutch setting. They may drill successfully into softwood or drywall but struggle with hardwood, thick metal, or large holes. A tool that only accepts screwdriver bits cannot hold an ordinary drill bit unless a suitable adapter is designed for that specific holder.

Do not confuse a cordless screwdriver with an impact driver. An impact driver can deliver much higher torque, but its hammering action and bit compatibility make it a different tool. For ordinary drilling, a standard cordless drill with a smooth rotary mode is usually easier to control.

Check the Tool Before Attaching a Bit

Inspect the front of the tool and identify how it holds accessories. A keyless chuck has three jaws that open and close around the bit. A quick-change hex holder accepts bits with a compatible hex shank, usually by pulling the collar forward, inserting the bit, and releasing the collar.

Look for a variable-speed trigger, forward and reverse controls, and a clutch ring with numbered settings. These features make drilling easier, but their presence does not guarantee that the tool has enough power for every material. Check the manufacturer’s stated drilling capacity when available, especially for metal or large-diameter bits.

Examine the battery as well. A partially charged or aging battery can cause early stalling, reduced speed, and excess heat. A small battery-powered screwdriver may be perfectly suitable for a few pilot holes but unsuitable for continuous drilling.

• Confirm that the bit fits the chuck or holder securely.
• Check that the bit is rated for the material being drilled.
• Make sure the battery is charged and properly latched.
• Inspect the tool, bit, and battery for cracks, looseness, or damage.
• Remove the battery before changing accessories if the tool could be triggered accidentally.

Choose the Correct Drill Bit

The material determines the bit style. A standard twist bit can handle many plastics and thin metals, while a brad-point bit produces cleaner holes in wood. A masonry bit is intended for brick, block, or concrete, but using one with a basic cordless screwdriver is generally ineffective because masonry drilling usually requires more power and, often, hammer action.

For drywall, a sharp general-purpose bit or a specialized drywall bit can make a clean opening. For wood, a brad-point bit helps prevent wandering and gives the hole a more defined edge. For metal, use a sharp high-speed steel twist bit and apply steady, moderate pressure rather than forcing the tool.

Use a hex-shank drill bit when the screwdriver has a quick-change holder. Do not insert a smooth round-shank bit into a holder that cannot clamp it. An adapter may work for light drilling, but it can add wobble and reduce the grip, particularly when drilling larger holes.

Match the bit diameter to the task. Small pilot bits place less demand on the motor, while large bits require substantially more torque. If a hole must be wide, start with a smaller bit and enlarge it gradually only when the tool remains stable and cool.

Set Speed, Torque, and Direction

Use a slow speed when starting the hole. Slow rotation helps the bit stay centered and reduces the chance of scratching the surface or creating an oversized entry point. Once the bit has formed a stable opening, increase speed only if the material and tool respond smoothly.

Set the clutch to the drill symbol if the screwdriver has one. Numbered clutch settings are intended to stop screw driving at a selected torque, and a low setting may cause the tool to stop before the bit penetrates. If there is no drill setting, begin with a higher torque setting and let the motor do the work without excessive downward force.

Set the direction switch to forward for normal drilling. Reverse is useful for backing a bit out of a hole or clearing a stuck bit, but reversing while the bit is cutting can damage the hole and generate unnecessary friction.

Do not press the trigger fully from the beginning. Controlled trigger pressure gives better alignment and lets you notice wobble, stalling, scraping, or unusual heat before the problem becomes serious.

Prepare the Workpiece and Yourself

Mark the hole location with a pencil or an awl. On smooth surfaces, a small indentation gives the tip somewhere to start and helps prevent the bit from skating across the material. Confirm that no electrical wire, plumbing, or other hidden obstruction is behind the drilling area.

Secure loose material with a clamp or place it on a stable work surface. Holding a small piece in one hand while drilling with the other can cause the material to spin, split, or strike your fingers. Keep the workpiece supported near the hole, but leave enough clearance for the bit to pass through.

Wear safety glasses because even a small bit can eject chips. Avoid loose clothing, jewelry, and gloves that could catch in a rotating chuck; gloves may be appropriate for handling rough material, but they should not replace safe distance from the spinning accessory.

Protect finished surfaces with masking tape when appropriate, particularly on painted or laminated material. Tape can reduce surface splintering and make the mark easier to see, although it does not compensate for a dull or unsuitable bit.

How to Use a Cordless Screwdriver as a Drill

1. Remove the battery or lock the tool safely. Install the correct bit only when the trigger cannot start the motor unexpectedly.
2. Insert and tighten the bit. Center a round-shank bit evenly in a three-jaw chuck, or push a compatible hex bit fully into the quick-change holder. Tug lightly to confirm that it is secure.
3. Mark and support the material. Create a small starting indentation and clamp the workpiece when possible.
4. Select forward rotation. Keep the direction switch away from the trigger while setting up.
5. Choose a low starting speed. Hold the tool straight, place the bit tip on the mark, and squeeze the trigger gently.
6. Apply steady, light pressure. Let the cutting edges remove material. Excessive force can stall the motor, bend the bit, or push the bit through the material suddenly.
7. Clear chips when needed. Withdraw the bit slightly while it is still rotating slowly, or stop the tool before clearing debris by hand. Never touch a bit immediately after drilling metal.
8. Reduce pressure near the exit. When the bit is about to break through, ease off to limit splintering and prevent a sudden grab.
9. Stop and inspect the result. If the hole is not large enough, enlarge it with the next appropriate size rather than forcing a large bit through in one pass.

For a through-hole in wood, place a scrap board beneath the workpiece. The backing board supports the fibers as the bit exits and can significantly reduce blowout on the rear face.

Control Heat, Stalling, and Bit Wobble

Heat is a warning sign, especially during metal drilling. A hot bit may lose its sharpness, discolor the workpiece, or become difficult to remove. Stop periodically and allow the tool and bit to cool; use a cutting lubricant suitable for the material when appropriate, but keep liquids away from the motor, battery, and electrical controls.

If the motor stalls, release the trigger immediately. Repeatedly forcing a stalled tool can overheat the motor and battery. Remove the bit, inspect the hole for packed chips, and switch to a smaller bit or a more powerful drill if the task exceeds the screwdriver’s capability.

A wobbling bit usually indicates that it is bent, poorly seated, incorrectly sized for the holder, or clamped off-center. Stop drilling and reseat it. Continuing with a wobbling bit creates an inaccurate hole and can stress the chuck or quick-change mechanism.

A clutch that clicks repeatedly while the bit barely advances is another clear limitation. The clutch is protecting the drive from excessive resistance, so increasing pressure is not the correct solution. Use a sharper, smaller, or more suitable bit, or change tools.

When a Cordless Screwdriver Is the Wrong Tool

Choose a regular cordless drill when the job involves many holes, hardwood, thick metal, large-diameter bits, or extended drilling. A drill generally offers a stronger motor, a more useful speed range, and a chuck designed for drilling accessories.

Use a hammer drill or rotary hammer for concrete, brick, and masonry when the application requires impact action. A small cordless screwdriver may spin a masonry bit, but it can take too long, overheat, or fail to make meaningful progress.

A hole saw, spade bit, auger bit, or large step bit can demand more torque than a compact screwdriver can provide. Follow the accessory maker’s intended tool type and diameter limits rather than assuming that a bit will work simply because it fits.

Stop using the screwdriver if the battery swells, the housing becomes unusually hot, smoke appears, a burning odor develops, or the chuck or bit holder becomes loose. Disconnect the battery and replace or repair the damaged component according to the manufacturer’s instructions.

Common Mistakes to Avoid

• Using a screwdriver bit instead of a drill bit for making holes.
• Running a large bit at full speed before creating a centered starting hole.
• Holding the workpiece by hand instead of securing it.
• Applying heavy pressure when the motor is already stalling.
• Using an ordinary round-shank bit in a hex-only holder without the correct adapter.
• Ignoring heat, burning smells, unusual noise, or battery problems.
• Drilling into a wall without checking for hidden wiring or plumbing.
• Using reverse rotation to cut a hole instead of using it only to withdraw a bit.

Frequently Asked Questions

Can you use a cordless screwdriver as a drill

Yes, it can drill small holes in wood when fitted with a suitable sharp bit. Softwood and thin boards are the easiest applications, while hardwood and large holes may require a full-size cordless drill.

What type of bit fits a cordless screwdriver?

The correct bit depends on the tool’s holder. A three-jaw chuck accepts many round-shank bits, while a quick-change holder requires compatible hex-shank drill bits or a secure, purpose-made adapter.

Can a cordless screwdriver drill through metal?

It can handle thin metal with a sharp high-speed steel bit and careful speed control. Use moderate pressure, clear chips, and allow the bit to cool. Thick metal or repeated holes are better suited to a cordless drill.

Should the clutch be set to a number

Use the drill symbol when the tool provides one. A numbered clutch setting may slip at a relatively low torque and stop the bit before it advances, although the exact controls vary by model.

Why does the screwdriver stop while drilling?

Stopping usually means the bit is meeting more resistance than the tool can overcome. A dull or oversized bit, low battery, excessive pressure, packed chips, or a low clutch setting can all cause stalling.

Can this method be used for concrete?

A basic cordless screwdriver is generally not appropriate for concrete or other masonry. Use a hammer drill or rotary hammer with the correct masonry bit when impact action and greater power are needed.

Is an impact driver suitable for drilling?

An impact driver can drill when paired with impact-rated accessories, but it is not the same as a standard drill. Its high torque and impact mechanism require careful control and may be excessive for delicate materials or small finishing holes.

Use It for Light Drilling, Not Heavy Work

A cordless screwdriver can make clean small holes when the bit, material, speed, and torque are properly matched. The major limitation is power: stalling, heat, wobble, or slow progress signals that the tool or accessory is being pushed beyond its safe range.

Start with a sharp compatible bit, secure the workpiece, drill slowly, and ease off before breakthrough. For masonry, large holes, thick materials, or repeated drilling, switch to a cordless drill or hammer drill rather than risking damage to the screwdriver or an inaccurate result.
