Chicago-latrobe 55467 Reduced Shank Drill Bit Hss

Product Description

The CHICAGO-LATROBE 55467 is a reduced shank twist drill bit designed for general-purpose portable drilling in metal, wood, and cast iron. The bit has a 1-3/64 inch (1.0469 inch decimal) cutting diameter paired with a 1/2 inch straight-cylindrical shank, allowing it to chuck into standard 1/2 inch capacity drill drivers even though the cutting diameter exceeds that shank size. The 118-degree standard point angle suits a wide range of common workpiece materials. The two-flute spiral design with a regular helix provides consistent chip evacuation throughout the cut. Built from high speed steel with a coated finish, this bit is suited for tradespeople and machinists who need reliable performance across production and maintenance drilling tasks.

This drill bit is intended for portable drilling applications across residential and commercial job sites, fabrication shops, and maintenance environments. It performs in wood, carbon steel, alloy steel, and cast iron. The reduced shank configuration makes it practical for operators who need to drill large-diameter holes without a dedicated large-chuck machine. Series 190 is a CHICAGO-LATROBE general-purpose line built to consistent dimensional tolerances for repeatable results across repeated use.

Installation Notes

Install and remove this bit only with the drilling tool unplugged or the power source disabled. Secure the shank fully in the chuck and tighten with a chuck key before operation. Wear appropriate eye protection when drilling metal or cast iron. For best results in steel, apply a cutting fluid to reduce heat buildup and extend bit life.
