Set of 13 cobalt metal drill bits from DEDRA with titanium nitride coating and cylindrical shank. It includes drill bits with 5% cobalt that increase resistance to thermal damage during drilling. The ground spiral ensures a low coefficient of friction and effective removal of excavated material.

The 135° point angle offers perfect centering and 40-60% faster drilling compared to standard HSS drill bits. It is intended for processing steel, cast iron, aluminum, copper, and brass. Manufactured according to the DIN338 standard.
