How to use

Select the appropriate drill bit size for the required hole diameter and secure it in the drill chuck. Use steady, perpendicular pressure and allow the drill to reach the correct speed for the material being worked. For wood and plastics, moderate speed and steady feed produce the best results; reduce speed and increase control when approaching the exit side to avoid splintering. Withdraw the bit periodically to clear chips and prevent heat buildup. After use, clean the bits and return them to the storage case to maintain organization and protect cutting edges.

Usage recommendations

For prolonged bit life and optimal hole quality, match drill speed and feed to the material, use appropriate clamping and backing support where needed, and avoid excessive side loading. Replace worn bits to maintain clean cutting and accurate hole diameters.
