Chicago-Latrobe 53459 59/64 in 118° Silver & Deming Drill 1/2 Reduced Shank

Chicago-Latrobe 53459 Drill Bit

This 59/64 inch Silver & Deming drill bit is built for heavy-duty drilling in metalwork and fabrication. The reduced 1/2 inch shank allows use in standard drill chucks while the cutting diameter handles large holes. It suits professional mechanics and industrial maintenance teams who need reliable performance on tough materials.

118 Degree Point Angle Limits

The 118 degree point angle is a general-purpose geometry that works across many ferrous and non-ferrous metals. It centres well without a pilot hole but can wander on very hard or abrasive alloys. The angle is not optimised for deep-hole chip evacuation or for high-speed production runs where specialised split-point or parabolic designs would cut faster.

Check Chuck Capacity Before Ordering

Verify that your drill press or hand drill accepts a 1/2 inch shank; smaller chucks will not grip this bit securely. Confirm the machine can deliver the torque required for a 59/64 inch cut without stalling. Ensure the workpiece material is compatible with cobalt steel cutting edges and that coolant or lubricant is available for the application.
