Feature

●Cobalt High Speed Steel (HSCobalt) is a variant of high-speed steel with a higher cobalt content. It has a high red hardness, which gives it much higher heat resistance. This allows cobalt tools to be operated at faster speeds and higher feed rates.
●The hardened straw surface is a stress relieving bronze coating that provides heat resistance and lubricity. This is a normal surface treatment for HSCo drills.
●135 degree split point angle Reduces the pressure needed to cut the drill. The split point is also self-centring, which means that the drill starts to cut exactly where it comes into contact with the material
●Floor grooves provide fast chip removal for maximum accuracy and efficiency
●For use on machines or handheld devices


Description

Heavy duty drill bit made of cobalt material with excellent heat resistance. For drilling steels with tensile strength up to 1400 N/mm², very hard bronze, stainless steels and heat and acid resistant steels. Can drill deep holes or bushings
