The HSS PRO-Co Cobalt DIN 338 cobalt steel drills are designed for drilling in stainless steel. Produced in the Danish Irwin joran factory.
The HSS PRO-Co drill body is made of high-quality high-speed steel containing 5% cobalt (Co). This additive ensures drill strength and hardness at high working temperatures (red-hot temperature). In addition, heat resistance extends the life of the drill. The hardened surface is gold-plated. 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 fast removal of chips.
