HSS PRO-Co Cobalt DIN 338 drill bits are designed for drilling 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 mixture ensures the strength and hardness of the drill bit at high working temperatures (red-hot temperature). Additionally, heat resistance extends the lifespan of the drill bit. The hardened surface is gold-colored. The 135-degree split point reduces pressure during drilling and ensures efficiency and excellent centering. The industrial-quality ground spiral guarantees precise drilling and fast chip removal.
