The HSS-E drill bit is a cobalt-alloyed high-performance drill bit. It has a reserve in high temperature strength even if the coolant supply is not optimal. Due to the alloy addition of 5% cobalt in the cutting material, these drills are well suited for machining workpieces with tensile strength above 800 N/mm². Ground, high-quality HSS drills. For metals, steel, Plastics, sometimes also wood. For wood there are special wood drills in our shop.
