Type of drill bits: Cobalt drill bits DIN 338 5%

HSS-Co Cobalt Drill Bits – DIN 338 (5% Cobalt)

Our HSS-Co drill bits are manufactured in accordance with DIN 338 standards from high-speed steel HSS-E (grade SK5 M) with the addition of 5% cobalt. This composition ensures enhanced cutting performance and increased resistance to high temperatures.

Technical Specifications:

Material: HSS-E with 5% cobalt

Point geometry: Cross-ground tip, type D

Point angle: 135°

Flute type: Type N (standard spiral)

Color: Brown (oxidized finish)

Manufacturing: Fully ground for high precision

Available sizes: Diameters from 1.0 mm to 13.0 mm

Applications:
HSS-Co drill bits are designed for machining alloyed and carbon steels with a tensile strength up to 1000 N/mm², as well as for stainless steel, grey cast iron, acid- and heat-resistant steels.

Important:
Use of appropriate cooling/lubrication is essential during drilling to extend tool life and ensure optimal performance.
