Chicago-latrobe 44286 Jobber Drill Bit Wire 16 Hss

Product Description

The CHICAGO-LATROBE 44286 is a jobber length drill bit designed for general-purpose drilling in metalworking and fabrication applications. Built from high speed steel with a bright uncoated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that aids in starting cuts cleanly without a center punch on many surfaces. The bit measures 0.1770 inches in diameter (wire size 16) with an overall length of 3.375 inches and a flute length of 2.1875 inches. It is suited for licensed tradespeople, maintenance machinists, and shop technicians who need a reliable general-purpose bit for non-ferrous metal and similar workpiece materials.

This drill bit is intended for use in hand drills, drill presses, and CNC drilling setups where a straight-cylindrical shank is required. It is sized in the wire gauge series, making it a common choice for tapping prep, electrical work hole sizing, and light fabrication tasks on non-ferrous metals. The 2-flute spiral design with a regular spiral type provides efficient chip evacuation during through-hole and blind-hole operations. Manufactured to DIN 338 standards, the 44286 fits into standard drill chucks without adapters.

Compatibility

Designed as a general-purpose jobber length drill bit compatible with standard 3-jaw drill chucks accepting a 0.1770-inch straight-cylindrical shank, suitable for drill presses, hand drills, and CNC equipment used on non-ferrous metal workpieces.

Installation Notes

Installation of this bit requires securing the straight-cylindrical shank firmly in a calibrated drill chuck before operation. Machinists and tradespeople should verify chuck capacity and ensure the bit is fully seated and centered to prevent runout. Apply appropriate cutting fluid when drilling non-ferrous metals to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows visible damage.
