Guhring 9002230015100 Size 53 Hss Stub Drill Bit

Product Description

The GUHRING 9002230015100 is a screw machine length (stub) drill bit designed for precise, short-reach drilling in metalworking applications. Built to DIN 1897 standards from M2 high-speed steel with a bright, uncoated finish, this bit is ground to a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. It carries a diameter of 0.0595 inches (Wire Size 53) and an overall length of 34.00 mm (1.3386 inches), making it well suited for use in screw machines, CNC lathes, and production drilling setups where rigidity and compact length are priorities. Right-hand cutting with a regular spiral flute pattern completes the standard configuration.

This stub-length drill bit is intended for production and precision drilling in steel and cast iron on both manual and CNC equipment. Its reduced overall length relative to a jobber-length bit increases rigidity and minimizes deflection in tight-tolerance holes. The straight cylindrical shank seats reliably in standard drill chucks and collet holders. Machinists, tool-and-die makers, and production drilling technicians working in metal fabrication, job shop, and manufacturing environments are the primary installers and users of this bit.

Key Features

• DIN 1897 stub-length design provides added rigidity and reduced deflection versus jobber-length bits
• M2 high-speed steel construction handles steel and cast iron at standard production cutting speeds
• 118-degree standard point angle with web thinning reduces entry thrust and improves centering
• Bright, uncoated finish suitable for use with standard cutting fluids or dry drilling
• Tapered web and regular spiral flute geometry promote efficient chip evacuation in short-depth holes
• Maximum drilling depth of 7.74 mm (0.3050 inches) consistent with 3xD stub-length classification

Compatibility

Designed as a DIN 1897 stub-length replacement drill bit for use in standard drill chucks and collet holders accepting a 1.51 mm (0.0594 inch) straight cylindrical shank. Primary workpiece materials are steel and cast iron.

Installation Notes

This bit is installed and used by machinists and production drilling technicians. Secure the shank fully in a properly sized drill chuck or collet before operation and verify runout is within acceptable tolerance for the application. Always apply appropriate cutting fluid for steel and cast iron unless dry drilling conditions are confirmed. Inspect the cutting edges for wear or chipping before each use, as a damaged point on a small-diameter bit can cause hole oversize or breakage.
