Guhring 9024630090000 Screw Machine Drill Bit 9mm

Product Description

The GUHRING 9024630090000 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in aluminum and other non-ferrous materials. The bit measures 9.00 mm (0.3543 inches) in diameter with an overall length of 84.00 mm (3.307 inches) and a flute length of 40.00 mm (1.575 inches). Built to DIN 6539 standards and manufactured from K40 carbide grade, it features a web-thinned, faceted 118-degree drill point and a straight-cylindrical shank. The coated finish and two-flute spiral configuration support controlled chip evacuation and consistent hole quality in production environments.

This drill bit is intended for use in CNC machining centers, drill presses, and similar production equipment where stub-length rigidity is preferred over jobber-length reach. Its 3xD flute-to-diameter ratio and maximum drilling depth of 1.043 inches (26.50 mm) make it well-suited for through-holes and shallow blind holes in aluminum and comparable workpiece materials. Machinists, tool-and-die technicians, and precision manufacturing shops running high-cycle operations are the primary users of this tool.

Key Features

• Solid carbide K40 grade construction for hardness and wear resistance
• 118-degree faceted drill point with web thinning for reduced thrust and cleaner entry
• DIN 6539 standard compliance ensures dimensional consistency
• Stub (screw machine) length provides added rigidity and reduced deflection
• Two-flute spiral design promotes efficient chip removal
• Straight-cylindrical shank fits standard drill chucks and collet toolholders

Compatibility

Designed as a general-purpose solid carbide stub drill conforming to DIN 6539, suitable for use in standard drill chucks and collet systems accepting a 9.00 mm straight-cylindrical shank. Diameter tolerance is +0.000 to -0.010 mm.

Installation Notes

Secure the shank fully in the collet or chuck before operating and verify runout before beginning a drilling cycle. Power down the spindle completely before changing or inspecting the bit. Carbide tooling is brittle and should not be used in hand-held drill applications where lateral loading can cause fracture. Follow machine manufacturer guidelines and applicable workplace safety standards when setting speeds and feeds for the workpiece material.
