How to use

Secure the drill bit in the drill chuck according to the drill manufacturer's instructions, ensuring it is centered and tightened. Select an appropriate speed and feed rate for the material being drilled; start at a moderate speed for precise positioning, then increase as needed. Apply steady axial pressure, maintain alignment with the workpiece, and allow the bit to evacuate chips freely. Use cutting fluid when drilling metals if recommended for the material and bit type.

Usage recommendations

For longer bit life and safer operation, ensure proper clamping, moderate drilling speeds for harder materials, and periodic clearing of chips. Replace the bit if cutting performance deteriorates or if visible wear or damage appears.
