Guhring 9005520075400 Stub Drill Bit 19/64 Hss

Product Description

The GUHRING 9005520075400 is a screw machine length (stub length) drill bit designed for high-performance drilling in production and machining environments. Built to DIN 1897 standards, this bit features a 19/64 inch (0.2969 inch) diameter, a 130-degree split point, and a parabolic flute geometry that promotes faster chip evacuation and reduced thrust. The bright, uncoated high speed steel construction makes it well suited for cutting aluminum and other non-ferrous materials. Right-hand cutting with a straight-cylindrical shank, it fits standard drill chucks without adapters. The short stub-length body increases rigidity and reduces deflection in high-cycle applications.

This drill bit is built for production drilling operations where tool stiffness and chip clearance are priorities. The parabolic flute design handles aluminum particularly well, reducing chip packing in deep-entry passes. With a maximum drilling depth of 1.011 inches and a flute-to-diameter ratio of 3xD, it is appropriate for through-hole and moderate-depth drilling in machining centers, drill presses, and hand-held power tools. It is sold individually and is appropriate for use by machinists, tool-and-die tradespeople, and maintenance technicians working in light industrial settings.

Key Features

• DIN 1897 stub length for increased rigidity and reduced deflection
• 130-degree drill point angle with web-thinned tip for lower entry thrust
• Parabolic flute geometry for fast chip evacuation, especially in aluminum
• Bright/uncoated high speed steel finish compatible with cutting fluids
• Straight-cylindrical shank fits standard drill chucks directly
• Right-hand cut with parallel web configuration for consistent performance

Compatibility

Designed as a DIN 1897 Series 552 stub-length drill bit with a straight-cylindrical shank; fits any standard drill chuck accepting a 19/64 inch shank diameter. Primary workpiece material listed by the manufacturer is aluminum.

Installation Notes

Install and remove drill bits only when the spindle is fully stopped and the machine is powered down or the trigger is locked out. Confirm chuck capacity before seating the shank, and tighten to chuck manufacturer specifications using the appropriate chuck key. When drilling aluminum or non-ferrous metals, apply a compatible cutting fluid to extend tool life and improve finish quality. Inspect the cutting edges for wear or chipping before each use.
