Guhring 9024630064000 Stub Drill Bit 0.252in Carbide

Product Description

The GUHRING 9024630064000 is a stub-length (screw machine length) solid carbide drill bit designed for precision hole-making in aluminum and other non-ferrous materials. It features a 0.252-inch (6.40 mm) diameter, a 118-degree faceted point angle, and a web-thinned tip geometry that reduces entry force and improves centering. The two-flute spiral design and regular helix promote efficient chip evacuation in short-depth drilling applications. At 2.756 inches overall length with a 1.22-inch flute length, this bit fits standard straight-cylindrical shank tool holders used across CNC machining centers, drill presses, and manual screw machines.

This drill bit is suited for production and maintenance environments where compact tool length, rigidity, and consistent hole quality are priorities. Its stub-length profile reduces deflection in close-tolerance work, making it a reliable choice for machinists, toolroom technicians, and maintenance professionals working with aluminum, soft metals, and similar workpiece materials. The DIN 6539 standard designation confirms interchangeability within metric tooling systems.

Key Features

• Solid carbide construction (Grade K40) for wear resistance and long tool life
• Web-thinned 118-degree faceted point reduces thrust and improves hole entry accuracy
• Stub-length body minimizes deflection in short-depth, high-precision drilling
• Right-hand cut, two-flute spiral geometry supports efficient chip clearance
• Straight-cylindrical shank compatible with standard collets and drill chucks
• Meets DIN 6539 specification for consistent dimensional interchangeability

Compatibility

Designed for use in standard straight-cylindrical shank tool holders; suited for aluminum and similar primary workpiece materials as a general-purpose stub-length carbide drill per DIN 6539.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom technicians with the machine powered down and in a locked-out state. Ensure the shank is fully seated and the collet or chuck is torqued to the tool holder manufacturer's specification before operation. Inspect the cutting edges for chips or wear before each use, as carbide tooling is brittle and susceptible to damage from improper handling. Coolant-through is not supported on this bit; apply external coolant or cutting fluid appropriate for the workpiece material.
