4X LIFESPAN MATERIAL – Made from industrial grade M35 high-speed steel with 5% cobalt provides hardness for wear resistance, withstands max 1100 degreeF, for much faster cutting and extra longer life span when compared with an average HSS drill bit.. MULTIPLE APPLICATION – Perfectly suitable for drilling hard metal such as stainless steel, cast iron, high temperature alloy, titanium alloy. Moreover, they can also be applied to cutting duroplasts, wood and some other soft materials..

The grooves on the sides of the bits’ twisted shanks will bring metal shavings up and out of the hole as you drill..
