Guhring 9024630037300 Stub Drill Bit 0.147 in Carbide

Product Description

The GUHRING 9024630037300 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in high-demand shop and machining environments. Measuring 0.147 inches (wire size 26) in diameter, the bit features a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and improves centering accuracy. With a 2-flute spiral configuration and a straight-cylindrical shank, it fits standard drill chucks and CNC toolholders without adapters. Solid carbide construction provides the rigidity and wear resistance required when drilling aluminum and other non-ferrous materials at elevated speeds. This bit is manufactured to DIN 6539 standards and carries a K40 carbide grade designation, confirming consistent dimensional and metallurgical quality.

This drill bit is sized and configured for production machining, toolroom work, and precision fabrication applications. Its stub-length body reduces deflection compared to jobber-length bits, making it well suited for numerically controlled drilling operations, jig drilling, and tight-tolerance hole work in aluminum and similar workpiece materials. The overall length of 2.047 inches keeps the cutting zone close to the spindle nose, improving rigidity in high-RPM setups. Machinists, tool and die makers, and CNC operators working in job shops or manufacturing cells are the primary users of this bit.

Key Features

• Solid carbide construction in K40 grade for wear resistance and dimensional stability
• 118-degree faceted drill point with web thinning for reduced thrust and improved self-centering
• Stub (screw machine) length body minimizes deflection during high-speed drilling
• 2-flute regular spiral geometry promotes chip evacuation in aluminum and non-ferrous materials
• Straight-cylindrical shank fits standard drill chucks and ER collets without adapters
• Manufactured to DIN 6539 standards with a diameter tolerance of +0.000 to -0.010 mm

Compatibility

Designed as an OEM-style solid carbide stub drill for use in standard drill chucks, ER collet systems, and CNC machining centers that accept straight-cylindrical shank tooling in the 3.73 mm shank diameter range. Primary workpiece material is aluminum; general-purpose designation indicates suitability for comparable non-ferrous materials.

Installation Notes

This drill bit is installed and serviced by machinists and CNC operators following standard machine tool setup procedures. Ensure the spindle is fully stopped and the machine is powered down or in safe mode before changing tooling. Secure the shank fully within the collet or chuck to the recommended grip depth to prevent pullout under cutting loads. Do not exceed the maximum drilling depth of 0.567 inches per pass without retracting to clear chips, as solid carbide is brittle and susceptible to breakage under lateral loading or chip packing.
