Guhring 9005520067500 Drill Bit Letter H Hss 130 Deg

Product Description

The GUHRING 9005520067500 is a screw machine length (stub) drill bit designed for high-performance drilling in steel, aluminum, and non-ferrous materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a parabolic flute geometry and a 130-degree cone relief point for improved chip evacuation and reduced thrust force in short-hole applications. The web-thinned, parallel web construction reduces cutting resistance at the chisel edge. Overall length is 2-29/32 inches, making it well suited for close-quarters drilling where standard-length bits are impractical. Installed by machinists and metalworking tradespeople, this bit meets DIN 1897 specifications.

This drill bit is intended for stub-length drilling applications in metal fabrication, production machining, and maintenance environments. Its right-hand cutting direction and parabolic fast-spiral flute design promote efficient swarf removal when drilling steel and non-ferrous alloys. The straight cylindrical shank is compatible with standard drill chucks and collet holders. With a maximum drilling depth of 0.9400 inches and a 3xD flute-to-diameter ratio, it is optimized for short, accurate holes in ferrous and non-ferrous workpieces rather than deep-hole operations.

Key Features

• HSS construction with bright, uncoated finish for use in steel, aluminum, and non-ferrous materials
• 130-degree cone relief point with web thinning reduces thrust and improves hole entry accuracy
• Parabolic fast-spiral flute design promotes rapid chip evacuation in short-depth drilling
• Stub length (2-29/32 inches OAL) for use in confined or close-tolerance setups
• Straight cylindrical shank fits standard drill chucks and collet holders
• Meets DIN 1897 specification; Series 552 high-performance grade

Compatibility

Designed as a DIN 1897-compliant stub-length drill bit suitable for use in standard drill presses, CNC machining centers, and hand-held drill equipment with compatible straight-shank chuck capacity in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or metalworking tradespeople familiar with cutting tool setup and safe machine operation. Ensure the spindle or drill chuck is fully powered down and the machine is locked out before loading or changing the bit. Verify chuck or collet capacity accommodates the 0.2656-inch shank diameter before tightening. Follow applicable workplace safety standards and machine manufacturer guidelines for feed rate and spindle speed selection when drilling the target workpiece material.
