Frequently asked questions
The DIN 338 designation guarantees standardization of all key tool parameters: angle, dimensions, and material. This standard is widely accepted in industry as a benchmark for quality and compatibility.
We recommend coolant emulsions or metalworking oils depending on the material. Proper cooling is essential to maintaining drill bit sharpness and producing high-quality holes.
For lower-strength structural steels, we suggest a range of 320-435 rpm; for harder grades, 270-360 rpm. These values follow machining guidelines for HSS tools of the given diameter.
