Guhring 9024630022000 Stub Drill Bit 0.0866 in Solid Carbide

Product Description

The GUHRING 9024630022000 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in high-production and close-tolerance applications. It measures 0.0866 inches (2.20 mm) in diameter with an overall length of 1.575 inches (40.00 mm) and a flute length of 0.512 inches (13.00 mm). The 118-degree faceted drill point and web-thinned geometry reduce entry force and improve centering accuracy. Conforming to DIN 6539 standards and manufactured from K40-grade carbide, this bit delivers consistent performance in demanding machining environments. It is sold individually and weighs approximately 0.05 pounds.

This drill bit is suited for drilling aluminum and similar non-ferrous materials in screw machine, CNC, and manual drill press applications. The stub-length design provides added rigidity compared to jobber-length bits, making it a practical choice when drilling shallow holes with minimal deflection. The straight-cylindrical shank seats directly into standard drill chucks and collet holders. It is commonly used in production shops, machine shops, and precision fabrication settings where hole quality and repeatability are priorities.

Key Features

• Solid carbide K40-grade construction for wear resistance and dimensional stability
• 118-degree faceted point with web-thinned geometry for reduced thrust and accurate entry
• Stub length (1.575 inches overall) provides superior rigidity over standard jobber bits
• Two-flute regular spiral design optimized for chip evacuation in aluminum and non-ferrous workpieces
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Conforms to DIN 6539 specification; diameter tolerance +0.000 to -0.010 mm

Compatibility

Designed as a general-purpose stub-length carbide drill bit per DIN 6539, suitable for use in CNC machining centers, screw machines, and drill presses equipped with standard straight-shank tool holders accepting a 2.20 mm (0.0866 inch) diameter shank.

Installation Notes

Install and remove this drill bit with the machine fully powered down and the spindle at a complete stop. Ensure the shank is fully seated and the chuck or collet is torqued to the machine manufacturer specification before operation. Solid carbide tooling is brittle and should not be used in setups with excessive runout or lateral loading. Inspect the cutting edges for chipping before each use and replace the bit if damage is observed.
