Guhring 9006680030500 Taper Length Drill Bit 0.1200 in Hss

Product Description

The GUHRING 9006680030500 is a taper length twist drill bit designed for precision drilling in metalworking and fabrication applications. Built from high-speed steel with a coated finish, this bit features a 130-degree point angle and a parabolic flute geometry that promotes efficient chip evacuation and reduced heat buildup during cutting. It carries a wire gauge size of #31, equivalent to 0.1200 inches in diameter, and conforms to DIN 340 standards for taper length drills. The web-thinned, parallel web configuration reduces entry resistance and improves hole quality. Licensed HVAC, plumbing, electrical, and mechanical trades rely on drill bits like this when fieldwork demands accurate, clean holes in structural or sheet metal components.

This drill bit is suited for right-hand cutting operations in aluminum alloy, brass, and steel. Its parabolic flute and 10xD flute-to-diameter ratio make it well matched for deeper hole applications where chip clearance is critical. The cylindrical shank with a diameter of 3.05 millimeters seats securely in standard drill chucks and collet holders. With an overall length of 4-3/16 inches and a flute length of 2-23/32 inches, it provides extended reach compared to jobber-length bits while maintaining rigidity for controlled drilling in production or service environments.

Key Features

• High-speed steel construction rated as high-performance grade for demanding metal drilling
• 130-degree point angle with web-thinned, parallel web for reduced entry force and improved centering
• Parabolic flute design with 10xD ratio supports efficient chip removal in deeper holes
• Coated finish extends tool life and reduces friction during cutting
• Conforms to DIN 340 taper length specification for dimensional consistency
• Right-hand cut with cylindrical shank — compatible with standard drill chucks and collet systems

Compatibility

Designed as an OEM-style taper length drill bit compatible with standard drill chucks and collet holders accepting a cylindrical shank. Rated for use in aluminum alloy, brass, and steel as stated by the manufacturer.

Installation Notes

Installation and use of this drill bit is typically performed by machinists, tool and die technicians, or trade professionals performing metal drilling tasks. Always secure the shank fully in the chuck or collet before operation and confirm the spindle is at a complete stop before changing tooling. Use cutting fluid or appropriate lubricant when drilling steel to extend tool life and maintain hole tolerance. Do not exceed the recommended maximum drilling depth of 2.537 inches for this bit diameter.
