Guhring 9003360067500 Taper Length Drill Bit 17/64 in

Product Description

The GUHRING 9003360067500 is a taper length cobalt steel drill bit designed for high-performance drilling in demanding materials. Built to DIN 340 standards, it features a 17/64 inch (0.2656 inch) diameter with a 130-degree standard point angle and a parabolic flute geometry. The parabolic flute promotes efficient chip evacuation and reduces heat buildup, making it well-suited for extended-reach drilling operations. Right-hand cutting with a web-thinned, parallel web configuration, this bit delivers consistent entry and reduced thrust in tough workpiece materials. It belongs to GUHRING Series 336 and is intended for professional machining environments.

This drill bit is rated for use in cast iron, hardened materials, stainless steel, and steel. With a flute-to-diameter ratio of 10xD and a maximum drilling depth of 3.617 inches (91.88 mm), it handles deep-hole drilling tasks where standard-length bits fall short. The cylindrical shank is compatible with standard drill chucks and collet systems. Typical applications include production machining, toolroom work, and maintenance drilling where material hardness or hole depth rules out conventional high-speed steel tooling.

Key Features

Compatibility

Designed for use in cast iron, hardened materials, stainless steel, and steel. The cylindrical shank fits standard drill chucks and collet holders sized for 17/64 inch shank diameter tooling.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool operators familiar with cutting tool selection and machine setup. Secure the cylindrical shank fully in a properly sized chuck or collet before operation, and verify that spindle speed and feed rate are appropriate for the workpiece material and hole depth. Inspect the cutting edges for wear or damage before each use. Follow all applicable machine guarding and personal protective equipment requirements for the work environment.
