How to use

Select a drill or drill press with a suitable chuck, securely clamp the 4 mm bit, mark the drilling point and start at low speed to center the drill. Increase speed as appropriate for the material, applying steady pressure without forcing the bit. After drilling, retract the bit while the drill is still turning to clear chips and avoid binding.

Recommendations

Use cutting fluid when drilling metals to extend bit life and reduce heat. For precise holes, use a pilot mark or center punch on harder surfaces and ensure the workpiece is firmly clamped.
