How to use

Select the Bosch 2 608 588 138 4 mm drill bit and fit it securely in the chuck of a compatible drill driver. Mark the drilling point, clamp the workpiece if possible, and use a steady feed rate with appropriate drill speed for the material. Apply moderate pressure and withdraw periodically to clear chips when drilling deeper holes. Use personal protective equipment such as safety glasses and gloves.

Recommendations

For best results, match drill speed to material: higher speeds for wood and lower speeds with steady feed for metals. Pre-drilling pilot points or using a center punch on metal improves accuracy. Inspect the bit for wear and replace when edges become dull to maintain hole quality.
