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