Guhring 9024630051600 Carbide Stub Drill Bit 13/64 in

Product Description

The GUHRING 9024630051600 is a solid carbide stub-length drill bit designed for high-precision drilling in demanding shop and production environments. Built to DIN 6539 standards, this Series 2463 bit features a 118-degree faceted point angle, web-thinned geometry, and a 2-flute spiral configuration that promotes clean chip evacuation. At 13/64 inch (0.2031 inches) in diameter, it fits standard straight-cylindrical shank toolholders and delivers consistent hole geometry in short-hole applications. Installation and operation are handled by machinists, CNC operators, and tool room technicians working with drilling machines, CNC machining centers, and manual drill presses.

This stub-length drill bit is rated for general-purpose drilling with a primary workpiece material designation of aluminum, though the solid carbide construction and coated finish support use in a range of non-ferrous and light ferrous applications. The stub-length format keeps deflection low and rigidity high, making it well suited for tight-tolerance production drilling and short-run precision work. The overall length of 2.441 inches and flute length of 1.024 inches accommodate a maximum drilling depth of 0.719 inches per pass, following a 3xD flute-to-diameter ratio.

Key Features

• Solid carbide construction with coated finish for extended tool life
• 118-degree faceted point angle with web-thinned geometry for accurate entry and reduced thrust
• Stub-length (screw machine length) format maximizes rigidity and minimizes deflection
• 2-flute regular spiral design promotes efficient chip clearance
• Straight-cylindrical shank fits standard collets and drill chucks without adapters
• Manufactured to DIN 6539 specification with K40 carbide grade for dimensional consistency
• Diameter tolerance held to +0.000 to -0.010 mm for repeatable hole sizing

Compatibility

Designed as a general-purpose stub-length drill bit compatible with any drilling machine, CNC machining center, or manual drill press equipped with a straight-shank toolholder sized for a 13/64 inch (0.2031 inch) diameter bit. Primary workpiece material designation is aluminum per supplier attribute data.

Installation Notes

A licensed machinist or qualified CNC operator should secure the bit firmly in a collet or drill chuck before operation, verifying shank seating depth and runout before engaging the spindle. Power down and de-energize all machine controls before changing tooling. Do not exceed the rated maximum drilling depth of 0.719 inches per pass without retracting to clear chips. Follow machine manufacturer guidelines and applicable shop safety standards for speeds, feeds, and coolant use with solid carbide tooling.
