How to use

Select the drill bit size required for the hole diameter and secure it in the drill chuck, ensuring proper tightening. Set the drill to the appropriate speed for the material: lower speeds for metals with suitable coolant, medium to high speeds for wood and plastics while avoiding overheating. Use steady pressure and let the bit cut at its own rate; withdraw periodically when drilling deep holes to remove chips. For accurate positioning, mark the drill point and, if needed, use a centre punch for metal or a pilot hole for larger diameters.

Usage recommendations

To extend bit life and achieve consistent results, match drill speed and feed to the material, apply cutting fluid or coolant for metal drilling, and store the set in a dry place. Replace worn bits to avoid poor hole quality and increased load on the drill motor.
