Chicago-latrobe 44077 Jobber Drill Bit Wire 7 Hss

Product Description

The CHICAGO-LATROBE 44077 is a jobber length drill bit sized to wire gauge number 7, equivalent to 0.2010 inches in diameter. Made from high speed steel with an oxide coating, it features a 118-degree standard point angle and a two-flute regular spiral design. The web-thinned, tapered web geometry reduces thrust and improves chip evacuation during drilling. Overall length is 3.625 inches with a flute length of 2.4375 inches. This bit is intended for use by machinists, maintenance technicians, and metalworking tradespeople who require a reliable general-purpose drill for production or repair work.

The 44077 is suited for drilling into cast iron and steel in general-purpose metalworking applications. The straight-cylindrical shank at 0.2010 inches in diameter fits standard three-jaw drill chucks on benchtop drill presses, hand drills, and milling machine spindles. Its Series 150 classification places it within a well-established line of general-purpose jobber bits designed for consistent performance across a broad range of ferrous materials and shop environments.

Installation Notes

Install and remove this bit only with the drill or press fully powered off and the chuck key removed from the chuck before starting the machine. Secure the workpiece firmly before drilling to prevent movement. Use appropriate cutting fluid when drilling steel at higher speeds to extend bit life and maintain hole tolerance. Cutting direction is right-hand only; do not use in reverse-rotation applications.
