How to use

Select the appropriate bit size and type for the material and fastener you are working with. Insert the bit into the drill or driver until it engages securely with the Flextorq interface.

After use, clean any debris from the bit and return it to the organizer case to maintain order and protect cutting edges.

Usage recommendations

For prolonged bit life, avoid excessive force and high-speed use on hard materials without appropriate cooling or reduced feed rates. Use the correct torque setting to prevent bit cam-out and inspect bits regularly for wear or damage, replacing any worn bits to maintain performance and safety.
