Precision Twist Drill 5999242 Jobber Drill Bit 67 Hss

Product Description

The PRECISION TWIST DRILL 5999242 is a jobber-length drill bit in wire gauge size 67, equivalent to 0.0320 inches in diameter. It is manufactured from high speed steel with a bright, uncoated finish and features a standard 118-degree split point. The spiral flute geometry is regular with a tapered web configuration and web thinning at the tip for improved penetration. Overall length is 1.375 inches with a 0.500-inch flute length. This is a general-purpose drilling tool suited for production and maintenance applications across a range of ferrous and non-ferrous materials.

This bit is designed for drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It carries a straight-cylindrical shank at 0.0320 inches in diameter and 0.875 inches in shank length, fitting standard collets and drill chucks without adapters. Typical use includes precision hole drilling in sheet metal, structural components, and machined parts where small-diameter accuracy is required. The two-flute spiral design provides efficient chip evacuation at drilling depths up to 0.500 inches.

Key Features

• Wire size 67 (0.0320 inches) for precision small-diameter drilling
• High speed steel construction for general-purpose use across multiple material types
• 118-degree standard point angle with web thinning for reduced entry force
• Regular spiral, two-flute design with tapered web for consistent chip removal
• Straight-cylindrical shank fits standard drill chucks and collets without adapters
• Bright uncoated finish for straightforward inspection and regrinding

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to ANSI standards, compatible with any standard drill chuck or collet accepting a 0.0320-inch straight shank. Part of the R10P, R15P, and R18P series from PRECISION TWIST DRILL.

Installation Notes

Install in a drill press, CNC machine, or hand drill with a chuck rated for the shank diameter before energizing the spindle. Secure the workpiece firmly before drilling to prevent movement at small bit diameters. Use cutting fluid appropriate to the workpiece material when drilling stainless steel, titanium, or superalloys to extend bit life. Inspect the cutting edges for wear before each use, as small-diameter bits are susceptible to breakage if run dulled or at excessive feed rates.
