Guhring 9005520043500 Drill Bit 0.1713 in Hss Stub

Product Description

The GUHRING 9005520043500 is a stub-length (screw machine length) twist drill bit designed for high-performance drilling in production and machine-shop environments. Built from high speed steel with a bright, uncoated finish, this bit features a parabolic flute geometry and a web-thinned, parallel-web construction that improves chip evacuation and reduces thrust load at the cutting point. The 130-degree drill point angle suits it well for aluminum and other non-ferrous metals. The straight-cylindrical shank accepts standard drill chucks. Overall length is 2.2835 inches with a flute length of 0.9450 inches, making it compact and rigid for short-reach applications.

This drill bit is rated as a high-performance grade tool and is built to DIN 1897 standards. Its primary listed workpiece material is aluminum, making it a practical choice for CNC machining centers, screw machines, drill presses, and manual machine work where stub-length rigidity reduces deflection and improves hole location accuracy. The 2-flute parabolic design clears chips efficiently in through-hole and blind-hole drilling operations. Maximum drilling depth is 0.6880 inches.

Key Features

• Diameter: 4.35 mm (0.1713 inches) with tolerance of +0.000 to -0.018 mm
• 130-degree point angle with web-thinned tip reduces entry force on aluminum and soft metals
• Parabolic flute geometry promotes fast chip evacuation and reduced heat buildup
• Stub (screw machine) length body provides maximum rigidity and minimizes deflection
• Straight-cylindrical shank fits standard drill chucks without adapters
• Manufactured to DIN 1897 specification for consistent dimensional quality

Compatibility

Designed as a DIN 1897 stub-length drill bit for use in standard drill chucks and collet systems that accept straight-cylindrical shanks; primary listed workpiece material is aluminum.

Installation Notes

Installation of this drill bit is performed by machinists and toolroom technicians using standard drill chucks or collet holders. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank fully into the chuck or collet to the depth recommended by the chuck manufacturer to prevent pullout under load. Do not exceed the maximum drilling depth of 0.6880 inches per the listed specification.
