Guhring 9024630076000 Stub Drill Bit 0.2992 in Carbide

Product Description

The GUHRING 9024630076000 is a stub-length (screw machine length) solid carbide drill bit designed for precise, high-performance drilling in production and machining environments. Measuring 0.2992 inches (7.60 mm) in diameter, it features a 118-degree faceted point angle and a web-thinned geometry that reduces thrust and improves chip evacuation at entry. The two-flute spiral configuration with a straight-cylindrical shank makes it compatible with standard drill chucks and collet holders. At 3.11 inches overall length with a 1.457-inch flute length, this bit is built for rigidity in short-reach applications where deflection must be minimized.

This drill bit is engineered for general-purpose drilling in aluminum and similar non-ferrous materials, though its solid carbide K40 grade construction supports use in a range of production settings. The stub (3xD) flute-to-diameter ratio suits CNC machining centers, turret lathes, and screw machines where compact tool length reduces vibration and improves hole-location accuracy. It carries a DIN 6539 specification designation and is suited for shops running moderate-to-high volume hole-making operations where consistent tolerances are required.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance

• Stub length (3xD flute ratio) minimizes deflection in short-reach drilling
• Straight-cylindrical shank fits standard chucks and collet systems
• Diameter tolerance of +0.000 to -0.010 mm for consistent, repeatable hole sizing
• Meets DIN 6539 standard

Compatibility

Designed as a DIN 6539 stub-length carbide drill bit for use in CNC machining centers, screw machines, and turret lathes; primary workpiece material listed as aluminum. No specific machine model compatibility was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with carbide cutting tools. Ensure the spindle and tool holder are clean and free of runout before seating the straight shank. Carbide tooling is brittle and should not be subjected to interrupted cuts or side loading beyond design parameters. Follow applicable shop safety procedures and machine guarding requirements during setup and operation.
