Guhring 9005520095800 Stub Drill Bit 0.3772 in Hss

Product Description

The GUHRING 9005520095800 is a screw machine length (stub) drill bit designed for high-performance drilling in production and machining environments. Built to DIN 1897 standards from high speed steel with a bright/uncoated finish, it features a parabolic flute geometry and a web-thinned, parallel-web configuration that improves chip evacuation and reduces thrust. The 130-degree point angle and standard point type make it well-suited for entry into aluminum and other non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks and collets. This is a right-hand cut tool with a 3xD flute-to-diameter ratio, sized at 0.3772 inches (Letter V) in diameter.

This drill bit is intended for use in screw machine operations, CNC machining centers, drill presses, and hand-held power tools where a short, rigid stub-length drill is required. Its parabolic flute design supports faster feed rates and cleaner chip removal, making it a practical choice for repetitive through-hole and shallow-depth drilling in aluminum and similar workpiece materials. The 0.3772-inch diameter corresponds to Letter V drill sizing. Maximum drilling depth is 1.127 inches. Machinists, tool-and-die makers, and production floor technicians working in metalworking shops are the primary users of this bit.

Key Features

• DIN 1897 stub length for increased rigidity and reduced deflection in short-reach applications
• Parabolic flute geometry with web thinning for improved chip flow and reduced cutting thrust
• 130-degree split point angle optimized for aluminum and non-ferrous workpiece materials
• High speed steel construction with bright/uncoated finish suitable for standard cutting speeds
• Straight-cylindrical shank compatible with standard drill chucks and ER collet systems
• Diameter tolerance of +0.000 to -0.022 mm for consistent, repeatable hole sizing

Compatibility

Designed as a DIN 1897-compliant stub-length drill bit for use with standard drill chucks, collets, and CNC toolholders accepting straight-cylindrical shanks in the 0.3500 to 0.4000 inch diameter range. Primary workpiece material designation is aluminum; suitable for other non-ferrous materials at appropriate cutting parameters.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with metalcutting operations. Ensure the machine spindle is fully stopped and the tool is properly seated and tightened in the chuck or collet before operation. Inspect the cutting edges for wear or damage before each use and replace when dimensional tolerance or surface finish degrades. Follow the machine manufacturer and tooling supplier guidelines for appropriate speeds and feeds for the workpiece material.
