How to use

Select the bit with the required diameter and insert it securely into the drill chuck according to the drill manufacturer’s instructions. Set the drill to an appropriate speed for the material: lower speeds for metals and harder woods, higher speeds for softer woods and plastics. Use steady pressure and avoid forcing the bit; allow the bit to cut the material. Clear chips regularly and, where appropriate, apply light lubrication when drilling metals. After use, clean the bits and store them in their kit to protect cutting edges.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves, and secure workpieces with clamps. Match drilling speed and feed to the material, and replace worn bits to maintain hole quality and reduce the risk of breakage.
