Chicago-Latrobe Jobber Drill 15/32" HSS 46230 pneumatic accessory

15/32" Jobber Drill for General Drilling

The Chicago-Latrobe 46230 is a jobber-length drill bit made from high-speed steel with a bright uncoated finish. Its 118-degree conventional point suits general-purpose drilling in metal, wood and plastic. The fractional 15/32 inch size equals 0.4688 inch decimal equivalent. It is designed for use in portable or stationary drills where a standard jobber length is required.

Sustained Cutting Behaviour

Under continuous load the uncoated HSS body relies on cutting fluid and proper speed to manage heat buildup. The 118-degree point distributes cutting forces evenly but will dull faster than split-point or coated alternatives in abrasive materials. Chip evacuation depends on the standard flutes without coolant-through capability, so deep holes require frequent pecking to prevent packing and overheating. The bright finish offers no thermal barrier for extended high-speed runs.
