Chicago-latrobe 44184 Jobber Drill Bit Letter N Hss

Product Description

The CHICAGO-LATROBE 44184 is a jobber length drill bit sized to Letter N (0.3020 inches) and manufactured from high speed steel with an oxide coating. Part of the Series 150 general purpose line, this bit features a standard 118-degree drill point angle and a regular spiral flute geometry with web thinning for reduced thrust during entry. The straight-cylindrical shank provides secure chuck engagement across standard drill equipment. With an overall length of 4.375 inches and a flute length of 3.0625 inches, this bit is suited to typical bench and hand-held drilling operations in production and maintenance environments.

The 44184 is designed for drilling cast iron and steel workpieces in general purpose applications. The two-flute right-hand spiral configuration promotes efficient chip evacuation in ferrous materials. The oxide finish provides a base level of lubricity and corrosion resistance during storage and use. This bit is a practical choice for machinists, maintenance technicians, pipefitters, and fabricators who need a reliable letter-size drill for hole-sizing and clearance drilling tasks in shop and field settings.

Installation Notes

Installation is performed by machinists and maintenance trades using standard drill presses, hand drills, or magnetic base drills. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck key removal prior to startup. Use appropriate cutting fluid or cutting oil when drilling steel to extend bit life and improve hole finish. Inspect the cutting edges before each use and redress or replace the bit if chipping or excessive wear is observed.
