Guhring 9024630083300 21/64 in Solid Carbide Drill Bit

Product Description

The GUHRING 9024630083300 is a solid carbide screw machine length drill bit designed for precision drilling in demanding shop environments. It carries a 21/64 inch (0.3281 inches) diameter, a 118-degree faceted point angle, and a web-thinned tip geometry that reduces thrust load at the cutting edge. The two-flute spiral design provides efficient chip evacuation, and the straight-cylindrical shank seats securely in standard drill chucks and collet holders. Manufactured to DIN 6539 in Series 2463 using K40 carbide grade, this stub-length bit delivers consistent dimensional accuracy within a +0.000 to -0.010 mm diameter tolerance. It is coated for extended tool life in general-purpose applications.

This bit is suited for stub-length drilling operations in aluminum and similarly machinable materials, where a shorter flute length improves rigidity and hole quality. The 3xD flute-to-diameter ratio and maximum drilling depth of 0.965 inches (24.51 mm) make it appropriate for CNC machining centers, drill presses, and screw machine setups requiring tight tolerances. Machinists and toolroom technicians typically reach for this bit when a standard jobber-length bit introduces too much deflection in short-reach applications. Coolant-through is not supported on this model.

Key Features

• Solid carbide K40 grade construction for wear resistance in non-ferrous and general-purpose materials
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Stub flute length (1.457 inches) increases rigidity compared to jobber-length alternatives
• Right-hand cut, two-flute spiral design promotes effective chip clearance
• Straight-cylindrical shank (8.33 mm) compatible with standard drill chucks and ER collets
• Manufactured to DIN 6539 specification for consistent quality and dimensional conformance

Compatibility

Designed as an OEM-style stub-length carbide drill bit suitable for use in CNC machining centers, drill presses, and screw machines accepting a straight-cylindrical shank. Primary workpiece material is aluminum; general-purpose performance is suitable for comparable non-ferrous and soft materials.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before beginning a production run. Follow applicable shop safety procedures and manufacturer feed-and-speed recommendations for carbide tooling in the target workpiece material.
