What to check before you order

Impact rating. Use impact-rated bits and adapters in impact drivers. Standard bits can snap under impact loads.
Shank type. Most driver bits use a 1/4 in. hex shank. Check that the shank fits your chuck or quick-change holder.
Tip fit. A worn or wrong bit cams out and strips screws. Replace bits as they wear.
Length. Insert bits are short and cheap to replace. Power bits are longer and reach recessed screws.
Oscillating blades. Confirm the blade mount matches your multi-tool and pick wood, metal or bi-metal teeth for the material.

For drilling, see drill bits and hole saws from Alfa Tool. Browse all power tools or drills and drivers.

Common questions

What is a nut setter?

A nut setter is a hex-shank socket that fits a drill or impact driver for driving hex washer head screws and small nuts. Many have a magnet inside to hold the fastener, and they are sized by the width across the hex, such as 1/4 in. or 5/16 in.

What is a torsion zone on a driver bit?

A torsion zone is a narrowed section of the bit shank designed to twist slightly under impact loads. It helps absorb torque spikes from an impact driver, which can reduce tip breakage and extend bit life.
