DIN 338 Titanium. Cutting drills are made of high quality (HSS) high-speed steel and have a 2.5µ titanium nitride coating. TIN coating hardens the surface up to 80HRC and is wear-resistant. TIN coating causes less friction effect, therefore, a cutting drill drills faster and generates less heat. 135 degree double-sharpened drill is designed for faster speed and easier drill centering. Recommended to drill the materials the hardness limit of which is up to 1000 N/mm2.
