Smith & ARROW professional Drill Bit Sets for all metal (M35 HSS Cobalt and M2 steel HSS). All of our high-speed steel (HSS) drill bits feature fully ground 135 degree split point, making it the perfect tool for working on materials such as metal, hardwood, and other industrial materials. Far more durable in temperature and hardness than traditional high-carbon steel, these bit sets are as good as they get.

Our cobalt jobber bits increases the strength of the steel and makes it more heat-resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit. They will perform and outlast normal HSS bits particularly if drilling tough metals. 135⁰ Split point cuts faster and reduces wandering and precision engineered shank ensures accurate hole size.

All drill bit sets come in a strong metal box set.
