Precision Twist Drill 5998764 Jobber Drill Bit 5/32 in

Product Description

The PRECISION TWIST DRILL 5998764 is a jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a steam oxide coating, it measures 5/32 inch (0.1563 inch decimal) in diameter with an overall length of 3.125 inches. The 118-degree standard point angle and regular spiral flute geometry deliver clean entry and efficient chip evacuation. The straight-cylindrical shank seats securely in standard three-jaw chucks. This bit is part of the Series R10-R15-R18 line and is suited for use by machinists, maintenance technicians, electricians, plumbers, and HVAC technicians who need a reliable general-purpose bit on the job.

This drill bit is intended for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It fits standard jobber-length applications where a 5/32-inch hole is required. With a flute-to-diameter ratio of 13xD and a maximum drilling depth of 2 inches, it handles typical through-hole and shallow blind-hole work in both shop and field settings. The single-piece per package format makes it easy to stock individually or in multiples for service trucks and shop toolboxes.

Key Features

• High speed steel construction with steam oxide coating for corrosion resistance and reduced friction
• 118-degree standard point angle for general-purpose drilling across multiple material types
• Right-hand cut, regular spiral flute with 2-flute configuration for efficient chip removal
• Web-thinned, tapered web configuration reduces thrust and improves hole entry
• Straight-cylindrical shank (0.1563 inch diameter) fits standard drill chucks without adapters
• ANSI-compliant construction to Series R10-R15-R18 specification

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw or keyless chuck accepting a 5/32-inch straight-cylindrical shank. Suitable for use in handheld drills, drill presses, and milling machines performing drilling operations per ANSI standards.

Installation Notes

Install in a properly sized chuck and tighten securely before use. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply cutting fluid or lubricant when drilling steel or stainless steel to extend bit life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
