Guhring 9005490047000 Jobber Drill Bit No. 13 Hss

Product Description

The GUHRING 9005490047000 is a jobber-length drill bit designed for precision hole-making in a range of materials. Built from high-speed steel with a bright, uncoated finish, this bit carries a No. 13 wire gauge diameter of 0.1850 inches and a 130-degree drill point angle suited for general and high-performance drilling applications. The parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup during operation. With an overall length of 3-5/32 inches and a flute length of 1-27/32 inches, it fits standard drill chucks and follows DIN 338 specifications. Licensed machinists, tool and die tradespeople, and maintenance mechanics are the primary users.

This drill bit is rated for use in aluminum as its primary workpiece material, with material codes K, N, and P covering non-ferrous metals and some plastics. It is well suited for production and maintenance environments where consistent hole quality and chip flow matter. The 5xD flute-to-diameter ratio supports drilling depths up to 1.5730 inches. The straight-cylindrical shank with a diameter of 0.1850 inches seats cleanly in standard keyless or keyed drill chucks, making it practical for both bench drill presses and handheld power tools.

Key Features

• No. 13 wire gauge size, 0.1850 inches diameter, conforming to DIN 338
• 130-degree standard point angle for clean entry and reduced thrust
• Parabolic flute design for fast chip evacuation in aluminum and non-ferrous materials
• Web-thinned, tapered web configuration reduces cutting resistance at the tip
• High-speed steel construction rated as high-performance grade
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style jobber-length drill bit conforming to DIN 338 standards, compatible with any standard drill chuck accepting a 0.1850-inch straight-cylindrical shank.

Installation Notes

This bit is installed by machinists and maintenance tradespeople using standard drill presses, CNC machines, or portable power drills. Secure the shank fully in the chuck before operation and verify runout if tolerance is critical. Apply appropriate cutting fluid when drilling aluminum to extend tool life and maintain hole quality. Disconnect or de-energize the drilling machine before changing bits.
