Guhring 9024630067500 Stub Carbide Drill Bit 17/64

Product Description

The GUHRING 9024630067500 is a stub-length (screw machine length) solid carbide twist drill bit designed for accurate, high-performance hole-making in aluminum and other non-ferrous materials. Built to DIN 6539 standards, this right-hand-cut bit features a 118-degree faceted point angle with web thinning to reduce entry force and improve centering. The 2-flute spiral configuration promotes efficient chip evacuation in shallow-to-moderate depth holes. With a 17/64 inch (0.2656 inch) diameter and an overall length of 2.913 inches, this bit is suited for machine tool applications where rigidity and dimensional accuracy are priorities.

This drill bit is intended for use in CNC machining centers, drill presses, and screw machines in industrial, manufacturing, and precision fabrication environments. The stub-length design provides greater rigidity compared to jobber-length bits, making it well suited for production drilling where hole location and roundness tolerances are tight. Primary workpiece material is aluminum, though the solid carbide construction with coated finish supports use in a range of non-ferrous materials. It is sized for direct spindle or chuck mounting with its straight-cylindrical 6.75 mm shank.

Key Features

• Solid carbide construction with coated finish for extended tool life and heat resistance
• 118-degree faceted point with web thinning for accurate entry and reduced thrust force
• Stub-length body (overall length 2.913 inches) delivers improved rigidity over standard jobber bits
• Right-hand cut, 2-flute regular spiral for efficient chip clearing in aluminum
• Maximum drilling depth of 0.940 inches with 3xD flute-to-diameter ratio
• Manufactured to DIN 6539 specification with K40 carbide grade

Compatibility

Designed as a Series 2463 stub-length carbide drill bit per DIN 6539, suitable for use in standard straight-shank drill chucks and collet systems accepting a 6.75 mm shank diameter. Primary workpiece material is aluminum; general-purpose tool performance rating applies.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool-and-die professionals familiar with carbide tooling. Always ensure the machine spindle and chuck are fully stopped and locked out before changing tooling. Carbide bits are brittle compared to high-speed steel; avoid side-loading or using in hand-held drills, which risk chipping the cutting edge. Verify chuck runout is within acceptable limits before production use to protect both the bit and the workpiece.
