Guhring 9007300068000 Stub Carbide Drill Bit 0.2677 in

Product Description

The GUHRING 9007300068000 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in metal fabrication, machining, and general industrial applications. Built to DIN 6539 standards, this bit features a 0.2677-inch (6.80 mm) diameter, a 118-degree faceted point angle, and a web-thinned tip geometry that reduces entry force and improves centering accuracy. The micrograin carbide construction delivers hardness and wear resistance well beyond high-speed steel alternatives. At 74.00 mm overall length with a 34.00 mm flute length, this is a rigid, compact tool suited for CNC machining centers and manual drill presses alike. Licensed machinists and tool-and-die professionals are the primary users.

This drill bit is rated for general-purpose performance with a primary workpiece material of aluminum, though its solid carbide construction handles a broad range of non-ferrous and ferrous materials in controlled machining environments. The stub-length body limits overhang and maximizes rigidity, making it a strong choice for short-hole drilling cycles, transfer-line operations, and fixtures where a longer bit would deflect. The straight-cylindrical shank seats directly into standard drill chucks or collet holders without adapters. Maximum drilling depth is 0.9370 inches (23.80 mm), consistent with a 3xD flute-to-diameter ratio.

Key Features

• Solid micrograin carbide construction for extended tool life in demanding materials
• 118-degree faceted point with web thinning for accurate self-centering and reduced thrust force
• DIN 6539 standard geometry ensures dimensional interchangeability with OEM tooling specs
• Bright/uncoated finish — compatible with cutting fluids and suitable for aluminum and non-ferrous machining
• Straight-cylindrical shank at 6.80 mm fits standard collets and drill chucks without adapters
• Stub-length body maximizes rigidity and minimizes deflection in short-cycle drilling operations

Compatibility

Designed as a general-purpose stub-length carbide drill bit conforming to DIN 6539 for use in CNC machining centers, manual drill presses, and transfer-line fixtures requiring a 6.80 mm straight-shank tool. Fits within the 0.2500 to 0.3000 inch (6.50 to 8.00 mm) drill bit size range.

Installation Notes

Installation and tool changes should be performed with the machine fully powered down and spindle locked. Seat the straight-cylindrical shank fully into the collet or chuck and verify runout before initiating a drilling cycle. Carbide is brittle — avoid interrupted cuts, side loading, or hammering the shank during tool changes. Follow the machine manufacturer and ANSI B11 safety guidelines for rotating tool operation.
