Guhring 9024630020000 Stub Carbide Drill Bit 0.0787 in

Product Description

The GUHRING 9024630020000 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in production and machine shop environments. Built to DIN 6539 specification, this right-hand, spiral-flute bit features a 118-degree point angle and web-thinned geometry that reduces entry force and improves chip evacuation. The submicron carbide grade provides the edge retention needed for consistent hole quality in high-cycle applications. With an overall length of 38 millimeters and a flute length of 12 millimeters, the short body minimizes runout and deflection in close-tolerance work. Installation is performed by machinists and toolroom technicians.

This bit is optimized for drilling aluminum as its primary workpiece material, though the general-purpose performance rating makes it suitable for a range of non-ferrous and soft materials. The stub-length format is a preferred choice for CNC machining centers, drill presses, and screw machines where rigidity and repeatability are priorities. The 3xD flute-to-diameter ratio and parallel web configuration support consistent chip clearing at a maximum drilling depth of 0.354 inches (9 millimeters). Series 2463 from GUHRING follows DIN 6539 standards for dimensional consistency across the tool line.

Key Features

• Solid submicron carbide construction for superior edge retention and wear resistance
• 118-degree drill point angle with web-thinned geometry reduces thrust and improves centering
• Stub-length body minimizes deflection and runout in precision applications
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank for compatibility with standard drill chucks and collets
• DIN 6539 compliant with a diameter tolerance of +0.000 to -0.010 millimeters

Compatibility

Designed as a DIN 6539 stub-length drill bit suitable for use in standard drill chucks and collet systems accepting a straight-cylindrical shank in the 0.0787-inch diameter range; primary workpiece material is aluminum per manufacturer specification.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the chuck or collet is clean and free of debris before seating the shank. Secure the bit to the full grip depth of the chuck or collet to prevent pullout under load. Do not exceed the maximum drilling depth of 0.354 inches per pass without retracting to clear chips.
