Heavy-Duty Cobalt Jobber Bit

The Chicago-Latrobe 44959 is a jobber-length drill bit made from cobalt with a TiAlN coating. It carries a 135 degree split point for self-centring starts and reduced walk. The bit is designed for portable and stationary drilling in tough alloys and stainless steel.

Suited to high-temp alloy work.

Machinists and maintenance technicians who need a non-coolant bit for hardened materials will find the split-point geometry helpful. Shops that require through-coolant delivery or a different point angle should select another tool.

135 degree split-point geometry

The 135 degree split point is the critical specification that determines whether this bit matches the application. It provides immediate centring without a centre punch and lowers thrust in hard metals..verify the angle before ordering.
