Chicago-Latrobe 53442 118 Degree 21/32 in Cobalt Drill Bit

Chicago-Latrobe 53442 Cobalt Drill Bit

This Chicago-Latrobe 53442 drill bit is a Silver & Deming style tool made from cobalt steel with a straw bronze finish. It features a 118 degree point angle and a reduced 1/2 inch shank for use in larger drill chucks. The bit is designed for drilling 21/32 inch diameter holes in tough materials. It suits machinists and maintenance technicians who need durable performance in metalworking applications.

Check Shank Compatibility Before Ordering

Verify that your drill press or heavy-duty hand drill accepts a 1/2 inch reduced shank before purchasing this bit. The 21/32 inch cutting diameter requires a machine with sufficient power and rigidity to handle the load. Ensure the tool holder or chuck can securely clamp the reduced shank without slippage during operation. Confirm the workpiece material is suitable for cobalt steel tooling and the 118 degree point geometry.

Cobalt Construction and Reduced Shank Design

The cobalt steel construction offers high heat resistance and wear resistance for extended tool life in abrasive or hard metals. The straw bronze finish helps identify the cobalt material and provides some corrosion protection. The reduced shank allows this large diameter bit to fit standard 1/2 inch capacity chucks on bench or floor drill presses. The 118 degree point is a general purpose geometry suitable for a wide range of ferrous and non-ferrous metals.
