Guhring 9024630087300 Carbide Stub Drill Bit 11/32

Product Description

The GUHRING 9024630087300 is a solid carbide stub-length (screw machine length) drill bit designed for precision hole-making in metalworking and machining applications. Measuring 11/32 inch (0.3438 inches) in diameter with a 118-degree faceted point angle, this bit delivers consistent, accurate entry in high-demand shop environments. The web-thinned point reduces thrust requirements and improves centering. With a 2-flute spiral configuration and a straight-cylindrical shank, it fits standard drill chucks and CNC toolholders. Machinists and tool-and-die technicians rely on this Series 2463 bit for close-tolerance work where carbide rigidity and dimensional stability are essential.

This stub-length drill bit is built for short, controlled drilling cycles typical of screw machine operations, CNC machining centers, and manual mills or drill presses. Its primary workpiece material designation is aluminum, making it well suited for non-ferrous machining. The reduced overall length of 3.307 inches provides added rigidity compared to jobber-length alternatives, helping to minimize deflection in production environments. The straight-cylindrical shank accommodates standard collet chucks and drill chucks without modification.

Key Features

• Solid carbide construction (Material Grade K40) for rigidity and wear resistance in non-ferrous materials
• 118-degree faceted drill point with web thinning for reduced thrust and improved centering
• Stub length overall (3.307 inches) reduces deflection in production drilling
• 2-flute regular spiral geometry promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet toolholders
• Conforms to DIN 6539 specification for consistent dimensional quality
• Drill bit diameter tolerance of +0.000 to -0.010 mm for close-tolerance hole sizing

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 where a straight-cylindrical shank toolholder is in use. Primary workpiece material designation is aluminum; consult Series 2463 application data for expanded material compatibility.

Installation Notes

This bit should be installed by a qualified machinist or tool setter familiar with carbide tooling requirements. Secure the shank fully within the collet or chuck to the recommended grip depth before operation, and verify runout before beginning a production cycle. Carbide tooling is brittle and should not be used with excessive side load or interrupted cuts without confirming suitability. Ensure spindle speeds and feed rates are appropriate for carbide in the target workpiece material to avoid chipping or premature tool failure.
