Hi, to sign in to your account,
This Bordo cobalt jobber drill bit is engineered from HSS cobalt with a 135 degree split point designed for self centring, efficient drilling with reduced friction. The bit's 135 degree point angles are ideal for general purpose use in drilling non-ferrous materials such as mild steel, cast iron, and even timber and plastics. It has a bronze finish (gold oxide). The metallic brown coloured temper treatment is used on cobalt tools for identification purposes.
