Guhring 9006680031700 Taper Length Drill Bit 1/8 in

Product Description

The GUHRING 9006680031700 is a taper length, high-speed steel drill bit designed for precision drilling in aluminum alloy, brass, and steel. Built to DIN 340 standards, it features a 130-degree standard point angle and a parabolic flute geometry for efficient chip evacuation in deeper-hole applications. The web-thinned, parallel-web configuration reduces thrust during entry, making it well suited for production-level drilling where hole quality and tool life are both priorities. A cylindrical shank and right-hand cut make this bit compatible with standard drill chucks and machine spindles. It is classified as a high-performance grade within the GUHRING Series 668 lineup.

This drill bit is intended for use in machine shop, manufacturing, and maintenance environments where taper-length geometry is required for greater reach than a jobber-length bit without sacrificing rigidity. A 10xD flute-length-to-diameter ratio supports drilling depths up to approximately 2.53 inches. The coated finish extends cutting life across repeated passes in aluminum alloy, brass, and general-purpose steel. Typical applications include CNC machining centers, drill presses, and manual milling setups in light industrial and fabrication settings.

Key Features

• DIN 340 taper length geometry for extended reach in deeper-hole drilling
• Parabolic flute design promotes fast, reliable chip evacuation
• Web-thinned parallel web reduces entry thrust and improves hole accuracy
• 130-degree standard point angle suitable for aluminum alloy, brass, and steel
• High-performance HSS construction with applied coating for extended tool life
• Cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style taper length replacement drill bit for use in standard drill chucks and machine spindles accepting a 3.17 mm cylindrical shank, consistent with DIN 340 tooling specifications.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools and applicable shop safety practices. Secure the cylindrical shank fully in the chuck and verify runout before beginning a cut. Power down the machine and lock out energy sources before changing or inspecting the bit. Do not exceed the rated maximum drilling depth of 2.53 inches without re-pecking to clear chips from the parabolic flutes.
