Guhring 9024630017800 Stub Drill Bit 0.07 in Carbide

Product Description

The GUHRING 9024630017800 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in tight-clearance applications. It carries a wire gauge size of #50, equivalent to 0.07 inches in diameter, and is built to DIN 6539 standards. The 118-degree faceted point and web-thinned geometry reduce entry force and improve centering accuracy. With a regular spiral flute and right-hand cut, this bit is suited for licensed machinists, tool-and-die technicians, and field service pros working on close-tolerance bores in metallic and non-ferrous components.

This drill bit is rated for primary use in aluminum and other non-ferrous materials, making it a practical choice for HVAC equipment fabrication, electrical panel work, and plumbing fixture drilling where small, accurate holes are required. The stub-length design limits deflection, which is especially useful when drilling shallow holes where a jobber-length bit would flex or wander. The straight-cylindrical shank seats securely in standard drill chucks and collet holders.

Key Features

• Solid carbide construction (Material Grade K40) for wear resistance in non-ferrous and abrasive materials
• 118-degree faceted point with web thinning for self-centering entry and reduced thrust
• Stub-length design (overall length 1.417 inches) minimizes deflection in shallow drilling operations
• Right-hand spiral flute with 3xD flute-to-diameter ratio for efficient chip evacuation
• Meets DIN 6539 standards with a tight diameter tolerance of +0.000 to -0.010 mm
• Straight-cylindrical shank compatible with standard drill chucks and collet systems

Compatibility

Designed as an OEM-style replacement or direct tooling option for applications requiring a #50 wire gauge, 0.07-inch diameter stub-length carbide drill bit conforming to DIN 6539 and Series 2463 specifications.

Installation Notes

This bit should be installed by a qualified machinist or trade professional using a properly sized drill chuck or collet holder rated for the shank diameter. Before installing or changing tooling, power down all rotating equipment completely and confirm the spindle is at a full stop. Avoid running this bit in ferrous or hardened steel without verifying the material grade compatibility, as solid carbide tooling is brittle and can fracture under lateral load or improper feed rates. General machining safety practices and applicable workplace codes should be followed at all times.
