Guhring 9024630027900 Stub Drill Bit 0.110in Carbide

Product Description

The GUHRING 9024630027900 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in demanding shop and production environments. Built to DIN 6539 standards, it features a 118-degree faceted point angle and a web-thinned tip geometry that reduces thrust and promotes clean entry. The 2-flute spiral configuration with regular helix evacuates chips efficiently, making it well-suited for aluminum and other non-ferrous materials. At 0.110 inches (7/64 inch, wire size #35) in diameter, this bit delivers tight tolerances within a +0.000 to -0.010 mm band. Licensed machinists, tool-and-die shops, and production facilities rely on this type of bit for high-accuracy, short-depth hole-making applications.

This drill bit is intended for use in CNC machining centers, drill presses, and screw machine setups where stub-length rigidity is required. Its straight-cylindrical shank accommodates standard collets and drill chucks. The coated solid carbide construction handles aluminum as the primary workpiece material and general-purpose applications where consistent hole quality matters. The 3xD flute-to-diameter ratio and a maximum drilling depth of 0.465 inches (11.82 mm) keep it optimized for shallow, precise bores in production settings.

Key Features

• Solid carbide construction with DIN 6539 specification compliance for dimensional consistency
• 118-degree faceted point with web thinning reduces entry thrust and improves hole accuracy
• 2-flute regular-spiral design promotes efficient chip evacuation in aluminum and non-ferrous stock
• Stub-length body (1.811 inches overall) maximizes rigidity and minimizes deflection in short-reach applications
• Straight-cylindrical shank fits standard collets and drill chucks without modification
• Diameter tolerance of +0.000 to -0.010 mm supports close-tolerance production work

Compatibility

Designed as a general-purpose stub-length drill bit in the Guhring Series 2463 line, suitable for use in CNC machining centers, drill presses, and screw machine setups accepting a 2.79 mm straight-cylindrical shank. Primary workpiece material is aluminum; also applicable to general-purpose non-ferrous drilling within the 0.100 to 0.150 inch diameter range covered by this series.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician familiar with carbide tooling. Ensure the spindle and chuck or collet are clean and concentric before seating the shank to prevent runout-induced breakage. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts beyond the tool's rated depth, and hand-feeding without controlled feed rate. Confirm maximum drilling depth does not exceed 0.465 inches for this stub-length configuration.
