Guhring 9024630052200 Carbide Stub Drill Bit 0.2055 in

Product Description

The GUHRING 9024630052200 is a solid carbide, screw machine length (stub) drill bit designed for precision drilling in demanding production environments. Built to DIN 6539 standards and offered in the Series 2463, it features a 118-degree faceted point angle and a web-thinned tip geometry that reduces thrust and improves centering at entry. At 0.2055 inches in diameter with a 2-flute spiral flute design, this bit is suited for fast, accurate hole-making in aluminum and other non-ferrous or soft metallic materials. A right-hand cut and straight-cylindrical shank make it compatible with standard drill chucks and collet holders commonly found on CNC machining centers, drill presses, and screw machines.

This stub-length drill bit is intended for production drilling applications where rigidity and repeatability matter. The shorter flute length of 1.024 inches reduces deflection compared to jobber-length bits, making it well-suited for close-tolerance work in aluminum, plastics, and similar workpiece materials. It is typically installed and used by machinists, tool-and-die technicians, and CNC operators in shop environments. The maximum drilling depth is 0.715 inches, appropriate for through-holes and blind holes in thin to medium stock.

Key Features

• Solid carbide construction with coated finish for extended tool life
• 118-degree faceted drill point with web thinning for reduced entry thrust and improved self-centering
• 2-flute regular spiral design promotes chip evacuation in aluminum and soft metals
• Stub length minimizes deflection for tighter positional tolerances
• Straight-cylindrical shank fits standard chucks and collet holders
• Conforms to DIN 6539 specification, material grade K40

Compatibility

Designed as an OEM-style production drill bit for use in CNC machining centers, drill presses, and screw machines accepting a straight-cylindrical shank. Primary workpiece material per specification is aluminum; general-purpose tool performance rating applies to compatible non-ferrous and soft metallic materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify chuck or collet concentricity before use to maintain hole-position accuracy. Do not exceed the rated maximum drilling depth of 0.715 inches per plunge without retracting to clear chips.
