Guhring 9005490032600 Jobber Drill Bit No. 30 Hss

Product Description

The GUHRING 9005490032600 is a jobber-length drill bit sized at No. 30 wire gauge (0.1285 inches decimal) manufactured from high-speed steel with a bright, uncoated finish. Built to DIN 338 standards, this Series 549 bit features a parabolic flute geometry and a 130-degree drill point angle, making it well-suited for high-performance drilling applications. The straight-cylindrical shank measures 0.1283 inches in diameter, and the overall length is 2-9/16 inches. The web-thinned, tapered web design reduces thrust and improves chip evacuation. Licensed HVAC technicians, machinists, and general trade professionals reach for this bit when precision hole quality and consistent tolerance are required.

This drill bit is rated for primary use in aluminum (material code K, N, P) and performs in general-purpose drilling tasks where a standard jobber-length tool is appropriate. The parabolic flute with a 5xD flute-to-diameter ratio supports efficient chip removal during through-hole and moderate-depth drilling operations. The 1-7/16-inch flute length accommodates a maximum drilling depth of 1.225 inches. It is sold individually (package quantity of one) and is appropriate for use in drill presses, CNC machines, or handheld power drills where a straight-cylindrical shank is compatible.

Key Features

• No. 30 wire gauge size, 0.1285-inch decimal diameter, with a tight tolerance of -0.018 to 0.000 mm
• High-speed steel construction with bright, uncoated finish for general-purpose cutting performance
• 130-degree drill point angle with standard point type for accurate starting and reduced walking
• Parabolic flute geometry (5xD ratio) promotes fast, clean chip evacuation
• Web-thinned, tapered web design reduces cutting thrust and extends tool life
• Conforms to DIN 338 specification for consistent dimensional accuracy

Compatibility

Designed for use with any drill press, CNC machining center, or handheld power tool accepting a straight-cylindrical shank. Optimized for aluminum and non-ferrous materials per material code K, N, P classifications. Suitable as an OEM-style replacement or direct-use jobber-length drill bit in Series 549 applications conforming to DIN 338.

Installation Notes

Install and remove drill bits only after the machine spindle has come to a complete stop and power has been disconnected or locked out per applicable OSHA lockout/tagout procedures. Verify chuck compatibility with the 0.1283-inch straight-cylindrical shank diameter before use. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling materials that generate significant heat. Inspect the cutting edges and flute surfaces for wear or damage before each use.
