How to use

Select the appropriate screwdriver bit or drill for the task and insert it into the drill or the quick-change holder. For drilling metal use the HSS drills with the correct diameter and apply steady feed at appropriate speed; for harder materials use the carbide-tipped universal drills. Use the countersink to prepare screw heads for flush installation. Ensure the bit is securely seated in the chuck or holder before operation and use correct torque settings on cordless screwdrivers to avoid overdriving screws.

Recommendations

Always wear suitable eye protection and follow the drill and screwdriver manufacturer’s safety instructions. Use cutting fluid when drilling metal with HSS bits to extend tool life. Store the set in the L-box to protect bits and maintain organization.
