Guhring 9024630025800 Carbide Stub Drill Bit 0.1015 in

Product Description

The GUHRING 9024630025800 is a solid carbide stub-length (screw machine length) drill bit designed for precision drilling in demanding production environments. Sized at 0.1015 inches (Wire Size 38) in diameter, it features a 118-degree faceted point angle and a web-thinned tip geometry that reduces thrust and improves centering on entry. The two-flute spiral configuration provides efficient chip evacuation. With an overall length of 1.693 inches and a flute length of 0.551 inches, this bit is built for rigid, close-tolerance work. It is manufactured to DIN 6539 standards from K40 carbide grade, making it well suited for high-speed, high-volume drilling cycles on automated machinery.

This drill bit is primarily intended for drilling aluminum and similar non-ferrous or soft materials, though its solid carbide construction and general-purpose tool performance rating support a broad range of production drilling applications. The straight-cylindrical shank measures 2.58 mm in diameter, fitting standard collet chucks and drill press spindles used in machining centers, CNC equipment, and screw machines. It is sold individually and is well matched for tool-room work, prototype machining, and high-cycle production setups where stub-length rigidity reduces deflection in shallow-to-moderate depth holes.

Key Features

• Solid carbide construction, K40 grade, for extended tool life in production drilling
• 118-degree faceted point with web-thinned geometry reduces entry thrust and improves hole accuracy
• Stub (screw machine) length of 1.693 inches overall delivers superior rigidity versus jobber-length bits
• Maximum drilling depth of 0.399 inches supports 3xD flute-to-diameter ratio applications
• Coated finish for improved wear resistance and surface lubricity
• Manufactured to DIN 6539 specification with diameter tolerance of +0.000 to -0.010 mm

Compatibility

Designed as an OEM-style replacement or direct tooling selection for Series 2463 stub drill applications requiring a 0.1015-inch (Wire Size 38) diameter, straight-cylindrical shank drill bit conforming to DIN 6539.

Installation Notes

Installation is performed by machinists and tool-room technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully and concentrically in the collet or chuck before tightening to the equipment manufacturer's specified clamping torque. Inspect the cutting edges and coating under magnification prior to use; carbide is brittle and should not be used in setups with excessive runout or interrupted cuts beyond the tool's rated capability.
