HSS PRO-Co Cobalt DIN 338 drill bits are designed for drilling in stainless steel. Produced in the Danish Irwin joran factory.
The HSS PRO-Co drill bit body is made of high-quality high-speed steel containing 5% cobalt (Co). This admixture ensures the durability and hardness of the drill at high working temperatures (red-hot temperature). In addition, heat resistance prolongs the life of the drill. The hardened surface is gold. 135-degree Split Point angle reduces pressure during drilling and ensures efficiency and perfect centering. The industrial quality ground spiral ensures precise drilling and fast removal of debris.
