Chicago-latrobe 44377 Drill Bit Letter G 0.2610 in Hss

Product Description

The CHICAGO-LATROBE 44377 is a jobber-length drill bit in Letter G size, equal to 0.2610 inches in diameter, manufactured from high speed steel with a bright uncoated finish. Part of the Series 150D line, it features a standard 118-degree drill point angle with web thinning for easier penetration and reduced thrust. The two-flute spiral design with a regular spiral type promotes efficient chip evacuation during drilling operations. With an overall length of 4.125 inches and a flute length of 2.875 inches, this bit is sized for general-purpose drilling tasks. It is installed and used by machinists, maintenance technicians, and skilled tradespeople working with non-ferrous metals and similar materials.

The 44377 is suited for general-purpose drilling in non-ferrous metals such as aluminum, brass, and copper. Its straight cylindrical shank, measuring 0.2610 inches in diameter and 1.25 inches in length, seats securely in standard drill chucks and compatible collet systems. The bright uncoated finish makes it well-matched for applications where coolant-through capability is not required and where moderate production volumes are typical. This bit conforms to DIN 338 standards, making it a reliable choice for shops that require dimensional consistency across tooling inventory.

Installation Notes

This drill bit is installed by machinists and maintenance technicians using standard drill presses, lapping machines, or portable power drills equipped with a compatible chuck. Secure the shank fully in the chuck before operation and verify chuck key is removed prior to starting the machine. Inspect the cutting edges before use and replace the bit if chipping or dullness is observed, as a damaged edge increases thrust load and reduces hole quality. No coolant-through capability is present on this bit; apply cutting fluid externally when working with materials that generate significant heat.
