Guhring 9005490138900 Jobber Drill Bit 35/64 Hss

Product Description

The GUHRING 9005490138900 is a jobber-length drill bit designed for precision hole-making in metalworking applications. Built from high-speed steel with a bright, uncoated finish, this bit features a parabolic flute geometry that improves chip evacuation and reduces heat buildup during extended drilling cycles. It carries a 130-degree split point for reduced walking and faster penetration into workpiece material. The overall length is 6-5/16 inches with a flute length of 4-1/4 inches, and the shank diameter matches the drill diameter at 35/64 inches. Right-hand cut direction and a straight-cylindrical shank make it compatible with standard drill chucks and CNC toolholding systems. Manufactured to DIN 338 specification with a high-performance grade designation.

This drill bit is rated for use in aluminum and non-ferrous materials, as well as general-purpose ferrous stock, reflected in the primary workpiece material codes K, N, and P. It fits common production drilling, maintenance, and repair scenarios across machine shops, fabrication facilities, and industrial service environments. The 5xD flute-to-diameter ratio supports deeper hole applications without a dedicated deep-hole tool. Packaged and sold individually, it is suited for both stock tooling and one-off replacement situations.

Key Features

• Parabolic flute geometry promotes efficient chip evacuation and reduces heat in the cut zone
• 130-degree point angle with web-thinned tip reduces thrust force and minimizes drill walk
• High-speed steel construction with bright uncoated finish for general-purpose metalworking
• Straight-cylindrical shank fits standard three-jaw chucks and common toolholding collets
• Manufactured to DIN 338 specification for consistent dimensional tolerances
• Maximum drilling depth of 3.432 inches supports typical through-hole and blind-hole work

Compatibility

Designed for use in aluminum, non-ferrous alloys, and general ferrous workpiece materials per primary material codes K, N, and P. Fits standard drill press chucks, CNC machining center toolholders, and hand drill chucks accepting a 35/64-inch straight-cylindrical shank.

Installation Notes

Install in a properly sized chuck or collet and confirm the shank is fully seated before operation. Power down or de-energize the machine spindle completely before changing tooling. Use cutting fluid or coolant appropriate for the workpiece material to extend tool life, noting this bit does not support through-tool coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace when the point geometry is visibly degraded.
