Precision Twist Drill 5997985 Jobber Drill Bit 41

Product Description

The PRECISION TWIST DRILL 5997985 is a jobber-length twist drill bit in wire gauge size 41, with a decimal diameter of 0.0960 inches. Made from high speed steel with a bright uncoated finish, this bit features a standard 118-degree point angle and a web-thinned, tapered-web tip for improved cutting entry. The two-flute regular spiral design promotes efficient chip evacuation during drilling operations. The straight-cylindrical shank measures 0.0960 inches in diameter, making it compatible with standard drill chucks. Licensed machinists, maintenance technicians, and metalworking tradespeople are the primary users of this tool.

This drill bit is intended for general-purpose drilling in a range of workpiece materials including steel, cast iron, non-ferrous metals, superalloys, and titanium. With an overall length of 2.375 inches and a flute length of 1.375 inches, it is well suited for close-tolerance drilling in tight spaces or on benchtop drill presses and CNC machinery. The 14xD flute-to-diameter ratio supports drilling depths up to 1.375 inches without coolant-through capability required. It conforms to ANSI standards and belongs to the R10H-R18H series.

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in standard straight-shank drill chucks on hand drills, drill presses, and CNC machining centers. Compatible with workpiece materials coded P (steel), K (cast iron), N (non-ferrous metals), and S (superalloys and titanium) per ISO material classification.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with metalworking equipment. Secure the straight-cylindrical shank fully in a drill chuck before operation, and verify chuck runout is within acceptable tolerance for the application. Always power down and lock out the machine before changing bits. Eye protection and appropriate workholding are required when drilling metal.
