How to Use a Cordless Drill: Bits, Settings, and Screw Driving

18. September 2026

A cordless drill earns its place in a home toolkit the first time you assemble furniture, fit a bracket, or repair a loose board. The trick is learning how the bit, speed, and clutch work together. With the right setup, you can make clean holes and seat screws without chewing up their heads or damaging the material.

Start by practicing on scrap wood. A few holes and screws will teach you more about how to use a cordless drill than immediately tackling a finished cabinet.

Get familiar with the controls

Most cordless drill/drivers have these controls, although their positions vary:

Control	What it does
Chuck	Holds the drill bit, driver bit, or bit holder
Trigger	Starts the motor; pressing farther usually increases speed
Forward/reverse switch	Changes rotation direction; a center position often locks the trigger
Gear selector	Selects a lower or higher speed range
Numbered clutch collar	Limits the turning force used for driving screws
Mode selector	Selects screwdriving, drilling, or hammer drilling, depending on the model

Check your drill’s manual before starting. Some tools combine the clutch and mode selector on one ring; others use separate controls.

Allow the drill to stop completely before changing gears or direction.

Choose a drill bit or a driver bit

These accessories do different jobs: a drill bit makes a hole, while a driver bit turns a screw.

Drill bits for making holes

Match the bit to the material:

Twist bits: Common general-purpose bits. High-speed steel bits are typically suitable for metal and can also drill wood.
Brad-point bits: Designed for wood, with a pointed center that helps position the hole accurately.
Masonry bits: Have a carbide tip for materials such as brick and concrete. Follow the bit instructions for the required drilling mode.
Specialty bits: Tile, glass, and other difficult surfaces need suitable bits and a specific technique.

Leave hammer mode off when drilling wood or metal and when driving screws. Tile generally requires a suitable bit and rotary drilling without hammer action.

Driver bits for screws

Match both the screw-head pattern and its size. Phillips, Pozidriv, Torx, and square-drive screws require their corresponding bits. Phillips and Pozidriv can look similar, but they are not interchangeable.

With the drill stopped, press the bit into the screw head. It should seat fully with little wobble. Replace rounded or worn bits; they slip more readily and damage screws.

Short insert bits are normally used in a compatible bit holder. Longer power bits can often be gripped directly in the chuck, provided their shank is suitable.

Fit the bit securely

Remove the battery before changing accessories. For a drill with a built-in battery, follow the manufacturer’s instructions for disabling the tool.

With a typical keyless chuck:

Turn the chuck sleeve by hand to open the jaws.
Insert the bit straight, keeping its smooth shank between all three jaws.
Tighten the sleeve firmly according to the manual.
Check that the bit is centered and secure.
Refit the battery, point the tool safely away, and briefly run it at low speed to check for wobble.

Do not tighten the chuck by gripping it while squeezing the trigger. If the bit wobbles, disconnect the battery and reseat it.

Understand speed and drill clutch settings

Speed controls how quickly the bit rotates. Torque is the turning force applied to it. Your drill uses different controls to manage these.

Use the gears and trigger together

Low gear, often marked “1,” provides slower rotation and more available torque. It is a useful starting point for screwdriving and larger holes within the tool’s capacity.

High gear, often marked “2,” provides faster rotation and is commonly used for smaller holes in wood.

Start slowly with the trigger so the bit stays on your mark. Increase speed once it is cutting steadily. Larger bits and metal drilling generally require slower speeds; follow the bit manufacturer’s guidance.

Set the clutch low, then increase it

The numbered collar limits torque during screwdriving. Lower numbers allow less turning force before the clutch slips; higher numbers allow more.

Drill clutch settings are relative to your tool. Setting “6” is not a universal torque value, and there is no single correct setting for every screw.

To find a suitable setting:

Select low gear and screwdriving mode.
Start at a low clutch number.
Drive a test screw into matching scrap material.
If the clutch slips before the screw seats, release the trigger and increase the setting gradually.
Stop when the head reaches the intended position.

A mechanical clutch usually makes a clicking or ratcheting sound when it slips. Release the trigger when that happens.

The drill-bit symbol normally selects drilling mode and bypasses the adjustable screwdriving clutch. Use it for boring holes. A binding bit can twist the tool sharply, so maintain a firm grip and use an auxiliary handle when the manufacturer requires one.

Secure the work and drill a pilot hole

Clamp loose material to a stable bench. Never hold a small piece in your palm while drilling it. Place scrap wood underneath a through-hole to protect the bench and reduce splintering at the exit.

Wear safety glasses, tie back long hair, and keep loose clothing, jewelry, and gloves away from rotating parts. Keep your supporting hand clear of the bit’s exit path.

A pilot hole guides a screw and reduces the force needed to drive it. It is especially useful in hardwood, thin pieces, and locations near board ends.

For an ordinary wood screw, start with the screw manufacturer’s pilot-hole recommendation. As a rough visual guide, compare the bit with the screw’s solid central core, excluding the threads. Hardwood often needs a slightly larger pilot than softwood.

To drill it:

Mark the position clearly.
Fit the appropriate bit and select drilling mode.
Set a depth stop if the hole must not pass through.
Hold the drill square to the surface.
Start slowly, then apply steady, moderate pressure.
Ease pressure as the bit approaches the far side.

For deeper holes, withdraw the rotating bit periodically to clear wood chips. If it stalls, release the trigger and investigate rather than forcing it.

Drive screws without stripping them

Change to the correct driver bit, select low gear, and restore a low clutch setting.

Seat the bit fully in the screw head before pressing the trigger. Keep the drill aligned with the screw and apply enough forward pressure to maintain engagement. Start slowly and ease off as the head approaches the surface.

Stop at the depth the fitting requires. A countersunk screw may need to finish flush; a screw holding a hinge or bracket should seat against the fitting without deforming it. Finishing delicate fasteners with a hand screwdriver gives you extra control.

If something goes wrong:

The bit jumps out: Stop immediately. Check bit size, wear, alignment, and forward pressure.
The clutch clicks too early: Check that the screw and pilot hole are suitable before increasing the setting.
The screw spins without tightening: The hole may be stripped. More torque will enlarge the damage.
The head sinks too deeply: Lower the clutch setting and slow down sooner.

Check for concealed services before drilling walls

Wall drilling needs an additional check for electrical cables, water pipes, and gas lines. The Electrical Safety Foundation’s DIY and power tool safety guidance specifically cautions against drilling where concealed wires or water pipes could be struck.

Inspect both sides of the wall where possible. Note outlets, switches, plumbing fixtures, and appliances nearby. These provide clues, but cables and pipes do not always follow predictable routes.

Use a suitable wall detector according to its instructions, scanning the area in several directions. A stud finder alone may not detect services, and no detector guarantees a clear path. Some live-wire detection functions require the circuit to be energized during scanning; follow the device instructions, then switch off relevant circuits before drilling.

Turning off power does not locate cables or prevent pipe damage. If you cannot establish a clear drilling path, have a qualified professional assess the location.

Choose fixings suitable for the wall and the load, follow their hole-size instructions, and limit drilling depth accordingly. Stop if you meet unexpected resistance or a protective metal plate.

Build confidence on scrap wood

Clamp two scrap pieces together, drill a pilot hole, and drive a matching wood screw using a low clutch setting. Repeat with small adjustments until you can seat the head neatly.

That short exercise builds the habits you will use on finished work: secure the material, match the bit, start slowly, and release the trigger as soon as the job is done.
