Frequently asked questions
The 118° point angle specified in DIN 338 is optimal for most structural steels. It provides a balance between cutting efficiency, chip evacuation, and cutting edge life.
We recommend water-based coolant emulsions or metalworking oils depending on the workpiece material. Proper lubrication is essential to maintaining drill bit sharpness and high hole quality.
For lower-strength structural steels, we suggest a range of 295-400 rpm; for harder grades, 250-330 rpm. These parameters follow machining guidelines for HSS tools of the given diameter.
