Guhring 9006520086100 Drill Bit Letter R Hss Tin

Product Description

The GUHRING 9006520086100 is a jobber length drill bit sized at letter R (0.3390 inches) designed for high-performance drilling in metal and non-ferrous materials. The bit is manufactured from high speed steel with a titanium nitride (TiN) coating that reduces friction and extends tool life under continuous use. It features a parabolic flute design with a 130-degree drill point angle and web-thinned, tapered web construction for efficient chip evacuation. Overall length is 4-29/32 inches with a flute length of 3-3/16 inches. This bit conforms to DIN 338 standards and is rated as a high-performance grade tool suitable for production and maintenance drilling applications.

This drill bit is intended for use on aluminum and a range of workpiece material classes including non-ferrous metals, plastics, and general-purpose materials. The straight-cylindrical shank fits standard drill chucks without adapters, making it a practical choice for machine shops, maintenance facilities, and industrial production environments. The parabolic flute geometry supports efficient chip clearing in deeper hole applications, with a maximum drilling depth of 2.6810 inches (68.09 mm). Right-hand cutting direction is standard for conventional drill press and handheld drill use.

Compatibility

Designed as a DIN 338 jobber length drill bit suitable for use with standard drill chucks accepting a 0.3390-inch straight-cylindrical shank. Primary workpiece material codes K, N, and P indicate suitability for aluminum, non-ferrous metals, and general-purpose materials.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation. Power down the drill press or disconnect handheld drill power before changing bits. Do not exceed the rated maximum drilling depth of 2.6810 inches without retracting to clear chips.
