How to use

Select an appropriate drill and secure the 4 mm bit in the chuck, tightening it to prevent slippage. For metal drilling, mark the drilling point and use a center punch if necessary to prevent bit wandering. Use steady pressure and a moderate feed rate; apply cutting fluid or lubricant when drilling harder metals to extend bit life. For wood, choose a controlled feed speed and avoid excessive force to reduce splintering; back the bit out periodically to clear chips when drilling deep holes. After use, clean the bit of debris and store it in a protective case or holder.

Usage recommendations

The Bosch 4 mm drill bit is intended for general-purpose work. For prolonged drilling in hardened steel or for high-volume industrial use, consider selecting a specialty bit designed for those conditions. Regularly inspect the cutting edges and replace the bit when signs of dulling or chipping appear to maintain hole quality and safe operation.
