Guhring 9024630016100 Carbide Stub Drill Bit 0.0635 in

Product Description

The GUHRING 9024630016100 is a solid carbide screw machine length (stub) drill bit designed for precision drilling in tight-clearance applications. Built to DIN 6539 standards and produced in Series 2463, this bit measures 0.0635 inches (Number 52 wire gauge) in diameter with an overall length of 1.339 inches. The 118-degree faceted point and web-thinned geometry reduce entry force and improve chip evacuation. The coated finish extends tool life in demanding production environments. This bit is installed and used by machinists, tool-and-die professionals, and precision fabrication shops requiring tight-tolerance hole quality.

This stub-length drill bit is suited for close-tolerance drilling operations where a standard-length bit would flex or chatter. The reduced flute length of 0.394 inches provides added rigidity, making it appropriate for use in CNC machining centers, drill presses, and manual machines working aluminum and other non-ferrous materials. The straight-cylindrical shank seats directly in standard chucks and collets without adapters. Maximum drilling depth is 0.299 inches, consistent with the 3xD flute-to-diameter ratio of this series.

Key Features

• Solid carbide construction with coated finish for extended tool life
• 118-degree faceted drill point with web-thinned geometry for reduced entry force
• Stub length design adds rigidity and reduces deflection in short-reach applications
• Right-hand cut, regular spiral flute for effective chip removal
• Straight-cylindrical shank fits standard chucks and collets without adapters
• Manufactured to DIN 6539 specification, Material Grade K40

Compatibility

Designed as a general-purpose stub-length carbide drill bit for use in aluminum and similar non-ferrous workpiece materials. Compatible with standard chucks and collets accepting a 1.61 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Ensure the machine spindle and chuck are fully stopped and de-energized before inserting or removing the bit. Carbide tooling is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper feed rates, or dropping the bit on hard surfaces. Verify chuck or collet runout is within acceptable limits before drilling to prevent premature breakage on a bit of this small diameter.
