Guhring 9007320069000 Carbide Jobber Drill Bit Letter I

Product Description

The GUHRING 9007320069000 is a solid carbide jobber-length drill bit in Letter I size (0.2717 inches), designed for precise, repeatable hole drilling in non-ferrous and light alloy materials. Built to DIN specification in the Series 732 platform, this bit features a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and improves centering accuracy. The bright, uncoated carbide construction provides dimensional stability and clean chip evacuation through its two-flute spiral configuration. Machinists and tool-and-die professionals will find this bit well suited to high-precision production runs where hole tolerance matters.

This drill bit is rated for general-purpose drilling with aluminum and similar non-ferrous workpiece materials (Primary Workpiece Material Code: N). The straight-cylindrical shank diameter of 0.2717 inches (6.90 mm) seats directly in standard keyed or keyless chucks and collet holders without adaptation. With a flute-by-diameter ratio of 5xD and a maximum drilling depth of 2.309 inches (58.65 mm), it handles typical jobber-depth through-holes in a single pass on CNC machining centers, drill presses, and manual mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous applications
• 118-degree faceted point with web thinning for reduced thrust and improved self-centering
• Two-flute regular spiral flute form promotes efficient chip removal
• Bright, uncoated finish preserves carbide sharpness without coating buildup concerns
• DIN-spec Series 732 geometry ensures dimensional consistency across production quantities
• Shank diameter tolerance h8 for accurate, repeatable chuck and collet fit

Compatibility

Designed as an OEM-specification solid carbide jobber drill bit for use in standard straight-shank chuck and collet tooling systems rated for Letter I (0.2717-inch) bore diameters.

Installation Notes

Installation and use should be performed by qualified machinists familiar with rotating cutting tool safety. Secure the shank fully within the chuck or collet to the recommended engagement depth before operating. Ensure the spindle and workpiece are fully stopped before changing or inspecting tooling. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when drilling carbide tooling into target materials.
