Chicago-Latrobe 52456 118 Degree Silver & Deming Drill 1/2 Reduced Shank

Chicago-Latrobe 52456 Silver & Deming Drill

The Chicago-Latrobe 52456 is a Silver & Deming drill bit designed for drilling large-diameter holes in metal and wood. It suits machinists and maintenance technicians who need a single bit to bridge the gap between standard twist drills and hole saws. The 118-degree point angle provides general-purpose cutting performance across common workpiece materials.

118-degree point and reduced shank limits

The 118-degree point angle is optimised for general-purpose drilling but may wander on very hard or angled surfaces without a pilot hole. The 1/2-inch reduced shank fits standard drill chucks yet limits the maximum hole size to the bit's 7/8-inch cutting diameter. High-speed steel construction with black oxide finish offers heat resistance but requires appropriate cutting speeds to prevent premature wear.

Check chuck capacity and material compatibility

Verify your drill chuck accepts a 1/2-inch shank before ordering. Confirm the workpiece material is suitable for high-speed steel cutting edges and that your drill press or hand drill delivers the required speed and torque for a 7/8-inch diameter cut. Ensure adequate coolant or lubrication is available for the intended application.
