Guhring 9007300052200 Stub Carbide Drill Bit 0.2055in

Product Description

The GUHRING 9007300052200 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in production and machining environments. Built to DIN 6539 standards using micrograin carbide, this bit delivers consistent hole quality in aluminum and other non-ferrous materials. It features a 118-degree faceted point angle, a right-hand spiral flute configuration, and a web-thinned tip to reduce thrust and improve chip evacuation. The straight-cylindrical shank measures 5.22 millimeters in diameter, and the overall tool length is 62.00 millimeters. It is sold as a single unit and suits both CNC machining centers and manual drill press setups.

This drill bit belongs to the GUHRING Series 730 and is intended for general-purpose drilling applications, with a primary focus on aluminum workpieces. Its stub-length body provides added rigidity compared to jobber-length bits, making it well-suited for short-hole drilling, fixture work, and applications where tool deflection must be minimized. The 3xD flute-to-diameter ratio and 26.00-millimeter flute length support efficient chip removal at moderate depths. Machinists and tool-and-die professionals working in job shops, production lines, and aerospace component manufacturing will find this bit appropriate for tight-tolerance work.

Key Features

• Solid micrograin carbide construction for wear resistance and dimensional accuracy
• DIN 6539 specification for consistent geometry and interchangeability
• 118-degree faceted point with web thinning to reduce entry thrust
• Stub-length design improves rigidity and reduces deflection in short-hole applications
• Bright/uncoated finish compatible with coolant-free aluminum drilling
• Diameter tolerance class h8 for close-fit hole sizing

Compatibility

Designed as a general-purpose stub-length drill bit suitable for use in CNC machining centers, drill presses, and multi-spindle machines accepting a straight-cylindrical shank. Primary workpiece material rating is aluminum; consult GUHRING application data before use on ferrous or abrasive materials.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank diameter compatibility with the collet or chuck system before use. Do not exceed the maximum drilling depth of 0.7150 inches in a single pass without retracting to clear chips.
