Precision Twist Drill 5999154 Wire 65 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999154 is a jobber-length drill bit in wire gauge size 65, equivalent to 0.0350 inches in diameter. Manufactured from high speed steel with a bright, uncoated finish, it features a 118-degree standard drill point and a two-flute regular spiral configuration for efficient chip evacuation. The straight-cylindrical shank measures 0.0350 inches in diameter and seats securely in standard drill chucks. At 1.5 inches overall length with a 5/8-inch flute length, this is a small-diameter precision bit suited for tight-tolerance drilling in metalworking and fabrication applications. It is designed for general purpose use and conforms to ANSI standards.

This bit is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is a fit for production shops, maintenance and repair operations, and toolroom work where consistent small-diameter hole quality is required. The web-thinned, tapered web design reduces thrust force on entry, which is important when working with hard or difficult-to-machine materials. It is part of the R10P-R15P-R18P series, which covers general purpose jobber-length tooling at this diameter range.

Key Features

• Wire gauge size 65, 0.0350 inches diameter for precision small-hole drilling
• 118-degree standard point angle suitable for a broad range of metals
• High speed steel construction for durability across general purpose applications
• Bright uncoated finish — compatible with coolants or cutting oils as needed
• Web-thinned tapered web reduces entry thrust on hard materials
• Two-flute regular spiral design promotes clean chip removal
• Conforms to ANSI standards for consistent dimensional accuracy

Compatibility

Designed as a general purpose jobber-length drill bit for use in standard drill chucks and CNC or manual drill press setups handling wire gauge size 65 applications. Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces.

Installation Notes

This bit is installed by machinists and tool-and-die or maintenance technicians using standard drill chucks that accommodate a 0.0350-inch straight shank. Ensure the chuck is fully tightened and the workpiece is secured before drilling. At this diameter, use appropriate cutting fluid to reduce heat buildup and extend tool life. Do not exceed the recommended flute depth of 5/8 inch when drilling to prevent deflection or breakage.
