Precision Twist Drill 5999132 Jobber Drill Bit Wire 6

Product Description

The PRECISION TWIST DRILL 5999132 is a jobber-length, high-speed steel drill bit in wire gauge size 6 (0.2040 inches decimal equivalent). It features a 118-degree standard point angle with web thinning for easier entry and reduced thrust, and a two-flute spiral design for efficient chip evacuation. The bright, uncoated finish makes it well-suited for general-purpose drilling operations across a wide range of metallic workpiece materials. It carries a straight-cylindrical shank for direct chuck mounting and is part of the Series R18P line. Licensed tradespeople and machinists reach for this bit when production or maintenance drilling calls for a reliable, standard-geometry tool.

This bit is intended for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. With an overall length of 3.75 inches and a flute length of 2.5 inches, it handles drilling depths up to 2.5 inches, which covers most standard jobber-length applications in fabrication, maintenance, and repair work at a 12xD flute-to-diameter ratio. The straight-cylindrical shank fits standard keyed and keyless drill chucks without adapters.

Key Features

• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction for general-purpose durability across metals and hard materials
• Two-flute regular spiral design promotes consistent chip evacuation during drilling
• Bright, uncoated finish allows for easy visual inspection of wear
• ANSI-standard geometry ensures dimensional consistency and interchangeability

Compatibility

Designed as an ANSI-standard jobber-length drill bit suitable for use in any standard drill press, hand drill, or machining center chuck accepting a 0.2040-inch straight-cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium as specified by the manufacturer.

Installation Notes

Installation is performed by machinists, maintenance technicians, or qualified tradespeople using a standard keyed or keyless chuck. Secure the shank fully in the chuck before operation and verify that the bit runs true with no visible runout before engaging the workpiece. Always use appropriate cutting fluid or coolant recommendations for the workpiece material to extend tool life, and wear proper eye and hand protection per applicable shop safety standards. Do not exceed the rated maximum drilling depth of 2.5 inches without clearing chips.
