Guhring 9007320023000 Carbide Jobber Drill Bit 2.3 Mm

Product Description

The GUHRING 9007320023000 is a solid carbide jobber-length drill bit designed for precision drilling in demanding materials. It measures 2.3 mm in diameter (0.0906 inches) with an overall length of 53 mm (2.087 inches) and a flute length of 27 mm (1.063 inches). The 118-degree faceted point geometry combined with web thinning reduces entry force and improves centering accuracy. Finished in a bright coating, this bit is suited for machinists, toolroom technicians, and production floor operators working with tight-tolerance holes in ferrous and non-ferrous workpiece materials at the smaller end of the jobber-length range.

This drill bit is intended for general-purpose drilling applications where a 2.3 mm hole diameter is required. The straight-cylindrical shank accepts standard drill chucks and collet holders, making it compatible with CNC machining centers, drill presses, and hand-held power tools. The 5xD flute-to-diameter ratio and regular spiral geometry support chip evacuation in through-hole and blind-hole operations. It is well suited for light-to-medium production runs where dimensional consistency and bit longevity matter.

Key Features

• Solid carbide construction in material grade DK120 for wear resistance and rigidity at small diameters
• 118-degree faceted point with web thinning reduces thrust force and improves entry accuracy
• Bright coating preserves sharp cutting edges without added coating thickness that could affect tolerance
• Right-hand spiral flute promotes consistent chip evacuation in standard drilling operations
• Straight-cylindrical shank fits standard drill chucks and collet systems without adapters
• Diameter tolerance of +0.000 to -0.010 mm supports close-fit hole requirements

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any machine tool or hand-held drill accepting a 2.3 mm straight-cylindrical shank, including CNC machining centers, drill presses, and standard keyless or keyed chucks.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Carbide bits are brittle compared to high-speed steel; avoid side loading, interrupted cuts without proper feed rates, or hand-flexing the bit during setup. Secure the shank fully in the collet or chuck to the recommended grip depth before operation, and ensure the spindle is completely stopped before changing tooling. No coolant-through capability is present on this bit, so external coolant or cutting fluid should be applied at the cutting zone when drilling harder materials to manage heat.
