Chicago-latrobe 55465 Reduced Shank Drill Bit Hss

Product Description

The CHICAGO-LATROBE 55465 is a reduced shank twist drill bit built for general-purpose portable drilling in a wide range of materials. The bit features a 1-1/64 inch (1.0156 inch decimal) cutting diameter paired with a 1/2 inch straight-cylindrical shank, making it compatible with standard 1/2 inch drill chucks without requiring a larger chuck capacity. Constructed from high speed steel with a coated finish, it delivers solid wear resistance across repeated use. The 118-degree standard point angle suits most common drilling applications. Two spiral flutes with a regular helix promote consistent chip evacuation during cuts.

This bit is suited for portable drilling operations in wood, alloy steel, carbon steel, and cast iron. The reduced shank design allows a larger-diameter bit to be run in a 1/2 inch chuck, which is practical on job sites where heavy-duty drills with larger chucks are not available. It fits into Series 190 tooling setups and is appropriate for both shop and field use by tradespeople who need a reliable general-purpose bit for structural, mechanical, or rough carpentry work.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with portable drilling equipment and bit selection. Secure the 1/2 inch shank fully in the chuck before operation and verify chuck tightness. Wear appropriate eye and hand protection during drilling. Do not exceed the rated speed range for the bit diameter and material being drilled.
