Precision Twist Drill 5997010 Drill Bit Size 30 Hss

Product Description

The PRECISION TWIST DRILL 5997010 is a jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Ground from high speed steel with a bright uncoated finish, it carries a 135-degree split-point geometry with web thinning for reduced thrust and faster penetration into the workpiece. The wire gauge size is 30, equal to 0.1285 inches in decimal, and the overall length is 2.75 inches with a flute length of 1.625 inches. The straight cylindrical shank and right-hand spiral flute design make this bit compatible with standard drill chucks used by machinists, maintenance technicians, and fabricators. It belongs to the Series QC21P and conforms to ANSI standards.

This drill bit is suited for production and maintenance drilling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The 13xD flute-to-diameter ratio and parabolic-style spiral fluting assist with chip evacuation during deeper passes up to the maximum drilling depth of 1.625 inches. It is sold individually and is appropriate for use in both manual drill press setups and CNC applications where a straight shank is required.

Key Features

• Wire gauge size 30 (0.1285 inches decimal) with matching straight cylindrical shank diameter of 0.1285 inches
• 135-degree point angle with web-thinned, tapered web configuration for lower entry thrust
• High speed steel construction rated for heavy-duty grade performance across multiple workpiece material categories
• Right-hand cut with regular spiral fluting for standard drilling operations
• Bright uncoated finish suitable for general-purpose use without coolant-through requirement
• Conforms to ANSI specification designation; Series QC21P

Compatibility

Designed as an OEM-style jobber-length drill bit replacement suitable for standard straight-shank drill chucks in drill press, hand drill, and CNC spindle applications where a wire gauge size 30 bit is specified.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance personnel. Secure the straight cylindrical shank fully in the chuck and verify concentricity before drilling. Inspect the cutting edges for wear or chipping before each use, as a dull point on high speed steel bits increases heat buildup and can damage the workpiece or shorten tool life. Follow applicable shop safety procedures including eye protection and workpiece clamping.
