Guhring 9024630052000 Carbide Stub Drill Bit 5.20mm

Product Description

The GUHRING 9024630052000 is a solid carbide stub-length drill bit designed for precise, high-performance drilling in demanding shop and production environments. Built to DIN 6539 standards, this bit features a 5.20 mm (0.2047 inch) diameter with a 118-degree faceted point and web-thinned geometry that reduces thrust and improves chip evacuation at entry. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With a 2-flute spiral flute design and a flute-to-diameter ratio of 3xD, it delivers reliable chip clearance across a range of general-purpose applications. Installation and use require no specialized tooling beyond a compatible chuck or collet system.

This drill bit is suited for general-purpose drilling operations in aluminum and similar non-ferrous materials, as noted by the primary workpiece material designation. The stub-length configuration provides added rigidity compared to jobber-length bits, making it well-suited for short-hole drilling, fixture work, and precision positioning where deflection must be minimized. It is typically used by machinists, toolmakers, and production drilling operators working on CNC machining centers, drill presses, or manual mills where tight tolerance and repeatable entry accuracy are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in general-purpose drilling
• 118-degree faceted point with web-thinned geometry reduces entry thrust and improves centering
• 2-flute regular spiral design promotes efficient chip evacuation
• Stub-length (3xD flute ratio) body minimizes deflection for tight-tolerance hole placement
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Manufactured to DIN 6539 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-specification solid carbide stub drill for use in standard straight-shank drill chucks and collet systems accepting a 5.20 mm shank diameter, conforming to DIN 6539 dimensions.

Installation Notes

This drill bit is installed and used by machinists and toolroom professionals. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify chuck or collet bore matches the 5.20 mm shank diameter to prevent runout. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and speed selection based on workpiece material.
