Guhring 9005520033000 Stub Drill Bit 0.1299 in Hss

Product Description

The GUHRING 9005520033000 is a stub-length (screw machine length) high speed steel drill bit designed for precision hole-making in aluminum and other non-ferrous materials. It features a parabolic flute geometry that promotes efficient chip evacuation in short, high-cycle drilling operations. The 130-degree split point reduces walking and thrust force at entry. With a web-thinned, parallel-web construction and a bright uncoated finish, this bit is suited for shops and field technicians who need accurate, repeatable results in tight-clearance or confined-space applications. It is sold individually and conforms to DIN 1897 standards.

This drill bit is a fit for production drilling, maintenance repair, and fabrication work where stub-length tools are preferred for rigidity and reduced deflection. The straight cylindrical shank seats directly in standard drill chucks and collet holders without adapters. Primary workpiece material is aluminum, though the high-speed steel construction handles a range of softer metals and plastics in low-to-moderate speed applications. The 3xD flute-to-diameter ratio keeps the tool compact for work in shallow-depth applications.

Key Features

• Parabolic flute geometry for fast chip evacuation in aluminum and soft metals
• 130-degree drill point angle with web thinning reduces entry thrust and walk
• Stub length construction increases rigidity and minimizes deflection
• Bright uncoated finish compatible with cutting fluids and standard HSS speeds
• Straight cylindrical shank fits standard drill chucks and collet holders
• Conforms to DIN 1897 specification

Compatibility

Designed as a stub-length drill bit for use in standard drill chucks and collet systems that accept straight cylindrical shanks. Primary rated workpiece material is aluminum per manufacturer specification.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with cutting tool safety. Secure the shank fully in the chuck or collet before operation and verify runout before drilling production parts. Always follow machine manufacturer speed and feed recommendations for HSS tooling in aluminum. Disconnect or lock out the machine from its power source before changing or inspecting tooling.
