Guhring 9007320068000 Jobber Drill Bit 6.8mm Carbide

Product Description

The GUHRING 9007320068000 is a jobber-length, solid carbide drill bit designed for precise, general-purpose drilling in production and maintenance environments. Built to DIN specification in the Series 732 line, it measures 6.8 mm in diameter with a 118-degree faceted point angle and a bright, uncoated finish. The straight-cylindrical shank seats securely in standard chucks, and the web-thinned tip reduces entry force and helps center the bit on contact. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 58.80 mm, this bit handles through-hole and blind-hole work reliably. Licensed HVAC, plumbing, and mechanical contractors as well as machinists specify solid carbide tooling when drilling non-ferrous metals and other demanding materials at higher feed rates.

This bit carries a primary workpiece material designation of N, indicating it is optimized for non-ferrous materials such as aluminum. It is well suited for light fabrication shops, HVAC equipment manufacturing, panel drilling, and field service applications where consistent hole geometry and surface finish matter. The 6.8 mm diameter is a common tap-drill size, making it a standard choice before threading M8 fastener holes. The two-flute spiral geometry efficiently clears chips in both manual drill press setups and CNC machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance compared to high-speed steel
• 118-degree faceted point with web thinning for reduced thrust and self-centering entry
• Bright, uncoated finish suitable for non-ferrous and general-purpose applications
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank in 6.8 mm diameter for compatibility with standard drill chucks and collets
• Built to DIN specification, Series 732, with h8 diameter tolerance for consistent fit

Compatibility

Designed as an OEM-style general-purpose jobber drill bit for use in standard drill chucks, collets, and CNC tool holders accepting a 6.8 mm straight-cylindrical shank. Optimized for non-ferrous workpiece materials per Series 732 DIN specification.

Installation Notes

Installation of this bit should be performed by a qualified machinist or trained technician familiar with rotary cutting tools. Secure the shank fully within the chuck or collet to the recommended grip depth before operation, and verify runout before drilling. Always power down and lock out the machine spindle before changing tooling. Do not exceed the rated maximum drilling depth of 58.80 mm in a single pass without retracting to clear chips.
