Chicago-latrobe 45650 Drill Bit Set 115 Pc Hss Jobber

Product Description

The CHICAGO-LATROBE 45650 is a 115-piece jobber length drill bit set covering a full inch-system range from 0.04 inches to 0.5 inches. Built from high speed steel with an oxide finish, each bit features a 135-degree split-point tip that starts on contact without a center punch and reduces walking on metal surfaces. The set spans fractional, wire gauge, and letter sizes, making it a single-case solution for general metalworking and multipurpose drilling tasks. It belongs to the Series 150ASP line and meets NAS 907 specification requirements. Licensed HVAC technicians, plumbers, electricians, and maintenance professionals who drill through metal as part of daily work will find this set covers virtually every common hole size in one kit.

This set is intended for metalworking and multipurpose drilling applications in both residential and commercial trade environments. The wire gauge range runs from number 60 to number 1, letter sizes run A through Z, and fractional sizes step in 1/64-inch increments from 1/16 inch to 1/2 inch. That coverage suits electrical panel work, sheet metal, conduit mounting, pipe hangers, and general mechanical fabrication. All bits cut right-hand with a straight shank for compatibility with standard keyed or keyless chucks. The included storage case is constructed of metal or plastic and keeps bits organized and indexed for fast size selection on the job.

Installation Notes

Installation of drill bits should be performed by a qualified tradesperson familiar with proper chuck seating and bit retention. Ensure the drill or drill press is powered down and the chuck is fully secured before beginning any drilling operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and improve cut quality. Follow applicable workplace safety standards and wear appropriate eye protection during all drilling operations.
