How to use
Mark the drilling point and secure the workpiece. Select an appropriate drilling speed for the material (lower speeds for metal, higher for wood). Clamp the drill bit in the chuck ensuring it is centred. Apply steady pressure and start drilling; periodically withdraw the bit to clear chips and cool the cutting edge. Finish the hole at a controlled speed to maintain accuracy.
Usage recommendations
For longer tool life and better results when drilling metal, use cutting fluid or lubricant and avoid excessive feed force. When drilling wood, clear chips frequently to prevent clogging. Replace the bit if signs of dullness or chipping appear.
