Guhring 9007320010200 Carbide Jobber Drill Bit No. 60

Product Description

The GUHRING 9007320010200 is a solid carbide jobber-length drill bit in wire gauge size No. 60, with a decimal diameter of 0.0402 inches. It features a 118-degree faceted point angle and a bright, uncoated finish. The two-flute, right-hand spiral design is web-thinned at the tip to reduce thrust and improve chip evacuation. At 34 mm overall length with a 12 mm flute length, this bit is sized for precision small-diameter drilling. It is suited for machinists, toolroom technicians, and production drilling operations requiring accurate, repeatable hole sizing in non-ferrous and similar materials.

This bit is part of the Guhring Series 732, rated for general-purpose drilling with a 5xD flute-to-diameter ratio. Its primary workpiece material designation is N, indicating suitability for aluminum and other non-ferrous materials. The straight-cylindrical shank with an h8 diameter tolerance seats securely in standard drill chucks and collets. Maximum drilling depth is 0.412 inches (10.47 mm), making it appropriate for shallow-to-medium depth holes in precision machining, electronics assembly drilling, and light production work.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS alternatives
• 118-degree faceted point for accurate self-centering on entry
• Web-thinned tip reduces axial thrust and minimizes workpiece deformation on thin or delicate stock
• Bright uncoated finish maintains dimensional accuracy and suits non-ferrous material drilling
• Right-hand spiral flutes with regular helix promote consistent chip clearance
• h8 shank tolerance ensures a precise fit in standard drill chucks and collets

Compatibility

Designed as a general-purpose replacement or production drill bit for applications requiring wire gauge No. 60 hole sizing in aluminum and non-ferrous materials, conforming to DIN specification standards.

Installation Notes

Solid carbide drill bits require rigid, vibration-free setups — use a quality drill chuck or collet that is rated for the shank diameter and confirmed to be in good condition. Power down all equipment and secure the workpiece before changing tooling. Avoid using carbide drills in handheld or flex-shaft applications where lateral loading can cause bit fracture. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling materials that generate heat.
