Choose the Correct Fit
Match the drill diameter to the required hole or pilot-hole specification before clamping the work.
Check the material and set a suitable drilling speed. Use the lubrication recommended for that material.
Installation & Care
Disconnect power before changing bits. Seat the shank securely and keep the drill aligned with the hole.
Clear chips safely with the tool stopped. Let the bit cool and inspect the cutting edges before reuse.

Important Product Questions
Is this the right diameter for my screw?
This bit makes a nominal 29/64 in hole. Check the screw or fastener instructions for the required pilot size; the screw diameter alone does not determine it.
Can I use it in an impact driver?
Use a drill with a compatible chuck. Do not treat a drill bit as impact-rated unless its own specifications explicitly allow impact-driver use.
How can I reduce heat while drilling?
Clamp the work, use a speed suited to the material and clear chips as needed. Follow the material and tool guidance on lubrication rather than forcing a dull bit.
