Guhring 9024630048500 Stub Length Drill Bit

Product Description

The GUHRING 9024630048500 is a stub-length (screw machine length) solid carbide drill bit with a 0.191-inch diameter and a 118-degree faceted point angle. Built to DIN 6539 standards from K40 carbide grade, it delivers consistent performance in close-tolerance drilling applications. The web-thinned point reduces thrust and improves centering at entry. With 2 spiral flutes and a straight-cylindrical shank measuring 4.85 mm in diameter, this bit is suited for use in CNC machining centers, drill presses, and screw machines. The coated finish extends tool life during repeated use in production environments. Licensed HVAC, plumbing, electrical, and mechanical contractors as well as machinists will find this bit sized for precise hole work.

This drill bit is designed primarily for aluminum as its primary workpiece material, though its general-purpose performance rating makes it applicable across a range of non-ferrous and soft ferrous materials. The stub-length body provides added rigidity compared to jobber-length bits, making it effective in applications where depth control and concentricity are critical. Overall length is 2.441 inches, with a flute length of 1.024 inches and a maximum drilling depth of 0.737 inches. The 3xD flute-to-diameter ratio suits short, controlled-depth holes in production and repair shop settings.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance
• 118-degree faceted point with web thinning for reduced entry thrust and improved self-centering
• DIN 6539 standard compliance for consistent dimensional tolerances
• Coated finish extends cutting edge life in repetitive drilling cycles
• Stub-length design increases stiffness and minimizes deflection in short-depth holes
• Straight-cylindrical shank compatible with standard drill chucks and collet systems

Compatibility

Designed as an OEM-style replacement or direct-use stub-length carbide drill bit for CNC machining centers, drill presses, and screw machines accepting a straight-cylindrical shank with a 4.85 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before changing or securing the bit in the chuck or collet. Verify shank seating and runout before beginning a drilling cycle. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and RPM selection based on workpiece material.
