Guhring 9007320013000 Solid Carbide Jobber Drill Bit 1.3mm

Product Description

The GUHRING 9007320013000 is a solid carbide jobber length drill bit designed for precision drilling in general-purpose applications. It carries a 1.3 mm diameter, a 118-degree faceted drill point, and a bright uncoated finish. The two-flute spiral design with web thinning promotes clean chip evacuation and reduces thrust at entry. With an overall length of 38 mm and a flute length of 16 mm, this bit suits light-duty precision work in small-diameter hole applications. It is sized to an h8 diameter tolerance, making it a reliable choice where hole location and dimensional accuracy matter. Machinists and toolroom technicians are the primary installers.

This drill bit is rated for general-purpose drilling with aluminum listed as the primary workpiece material, corresponding to material code N. The straight-cylindrical shank with a 1.3 mm shank diameter fits standard collet chucks and drill chucks configured for metric tooling. The Series 732 designation follows DIN specification standards. A maximum drilling depth of 14.05 mm and a flute-to-diameter ratio of 5xD make this bit well suited for shallow to mid-depth holes in non-ferrous metals, plastics, and similar materials where tight tolerances are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• 118-degree faceted point with web thinning to reduce entry thrust and improve centering
• h8 diameter tolerance for consistent hole sizing in close-tolerance work
• Regular spiral, right-hand cut with two flutes for efficient chip removal
• Bright uncoated finish suited for non-ferrous materials including aluminum
• DIN-specification Series 732 design for predictable performance and interchangeability

Compatibility

Designed as a general-purpose jobber length drill bit for use in CNC machining centers, drill presses, and hand-held drilling equipment fitted with collet or drill chucks accepting 1.3 mm straight-cylindrical shanks.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Ensure the machine spindle and chuck are fully de-energized and at rest before loading or removing the bit. Carbide tooling is brittle - avoid lateral loading, prying, or impact that can cause chipping or breakage. Verify chuck concentricity before running at speed to protect the tool and maintain hole tolerance.
