How to use

Select a spiral bit of the required diameter from the set and insert it into the quick-change chuck according to the drill manufacturer’s instructions. Ensure the drill is switched off and the workpiece is secured before starting. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material. Apply steady pressure without forcing the bit to maintain clean cuts and prolong bit life. Withdraw the bit occasionally for deeper holes to clear chips if necessary.

Recommendations

Use appropriate safety equipment such as eye protection and gloves. Match drill speed to the material: lower speeds for metals, moderate to higher speeds for wood and plastics. For prolonged use in metals, use cooling or reduced feed rates as needed. Store the bits in their case to protect cutting edges and maintain performance.
