Chicago-Latrobe 54068 135° Cobalt Jobber Drill Bit 7/16 in

Chicago-Latrobe 7/16 in Cobalt Drill Bit

The Chicago-Latrobe 54068 is a jobber-length drill bit made from cobalt steel with a TiN coating. It features a 135-degree split point for accurate starts and reduced wandering. Designed for non-coolant-through applications, it has zero coolant holes. This accessory suits professional and industrial drilling tasks requiring durability and heat resistance.

Suited for hard-metal drilling.

This bit serves machinists and maintenance technicians drilling stainless steel, titanium or other tough alloys where cobalt hardness and the TiN surface extend tool life. The split-point geometry aids hand-held or machine use without a centre punch. Buyers needing through-coolant capability or a different diameter should look at other options, as this model has no coolant holes and is fixed at 7/16 in.

135-degree split point cuts hard materials

The 135-degree split point is the decisive specification; it centres the bit instantly and reduces thrust when entering hard metals such as stainless steel or titanium. Combined with the cobalt substrate and TiN coating, this geometry delivers the cutting performance that determines whether the bit matches the workpiece material and machine rigidity.
