Step-by-Step Guide: How to Use an Impact Driver

Using an impact driver correctly involves a few key steps. Each step ensures safety, efficiency, and clean results.

Start by selecting the correct bit for the screw or fastener you are using. Insert it into the quick-release chuck until it locks securely in place.

Position your workpiece so it is stable and supported. If possible, clamp it down to prevent unwanted movement.

Hold the tool with a firm grip, placing one hand on the handle and the other steadying the body. Keep your stance balanced to handle sudden torque.

Place the bit directly into the screw head and align it straight. Misalignment often causes stripped screws and wasted effort.

Apply light forward pressure and slowly squeeze the trigger. Allow the tool to generate the force rather than pushing hard yourself.

Let the concussive action drive the screw until it is flush with the material. Release the trigger once the fastener is fully set.

How hard should I press?
Apply steady but light pressure — the tool supplies the force.

Do I need to pre-drill holes?
Yes, for hardwood and metal, pre-drilling prevents splitting and improves accuracy.

Should I feather the trigger?
Yes, short bursts give you better control and prevent overdriving.

How do I stop stripping screws?
Keep the bit aligned and use the correct size for the screw head.

Common Mistakes to Avoid

One of the biggest mistakes is using non-impact bits. These are not built to withstand torque and break easily.

Another mistake is overdriving screws into the material. This damages both the fastener and the surface, weakening the joint.

Many beginners forget to maintain control of the tool. The high torque can cause sudden jerks that lead to accidents or misalignment.

A common error is using an impact driver for drilling holes. It is not designed for precision drilling and often damages drill bits.

Why do bits keep breaking?
They are not impact-rated or have become worn from heavy use.

Why are screws stripping?
Improper alignment or applying too much torque causes stripping.

Can I drill holes with it?
Not efficiently, because it is made for fastening rather than drilling.

Why does it feel too loud?
Impact drivers make more noise due to the hammering mechanism inside.
