Guhring 9005520043700 Drill Bit 11/64 in 130 Deg Hss

Product Description

The GUHRING 9005520043700 is a screw machine length (stub) drill bit designed for high-performance drilling in steel, aluminum, and non-ferrous materials. It measures 11/64 inches (0.1719 inches) in diameter with a 2-9/32 inch overall length and a 15/16 inch flute length. The 130-degree cone relief point and parabolic flute geometry promote fast chip evacuation and reduced thrust in short-hole drilling applications. Web thinning and a parallel web configuration improve penetration and centering. This bit is manufactured to DIN 1897 standards and is intended for use by machinists, metalworking professionals, and industrial maintenance technicians.

This drill bit is suited for production and maintenance drilling in metal fabrication, general machining, and light manufacturing environments. The stub length body provides added rigidity in drill presses, CNC machining centers, and hand-held power tools where shorter reach reduces deflection. It is appropriate for drilling steel and non-ferrous metals such as aluminum and brass. The straight cylindrical shank is compatible with standard drill chucks without requiring special toolholding.

Key Features

• Parabolic flute geometry with fast spiral for efficient chip removal in deep and interrupted cuts
• 130-degree cone relief point with web thinning for reduced entry force and improved self-centering
• High-speed steel (HSS) construction, bright/uncoated finish suited for general-purpose metalworking
• Stub (screw machine) length body increases rigidity and reduces deflection compared to jobber-length bits
• Manufactured to DIN 1897 specification with parallel web configuration for consistent performance
• Maximum drilling depth of 0.687 inches; flute-to-diameter ratio of 3xD

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard 3-jaw drill chucks accepting a 0.1719-inch straight cylindrical shank, compatible with drill presses, CNC machining centers, and hand-held power drills used in metalworking applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or metalworking professionals familiar with proper cutting speeds and feeds for HSS tooling. Ensure the machine spindle is fully stopped and the chuck is secure before inserting or removing the bit. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not have a coolant-through channel. Consult applicable workplace safety standards and machine manufacturer guidelines before operation.
