Guhring 9007300051100 Stub Drill Bit 0.201 in Carbide

Product Description

The GUHRING 9007300051100 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in metalworking and machining applications. Manufactured to DIN 6539 standards, this Series 730 bit features a 0.201 inch (Wire Size #7) cutting diameter, a 118-degree faceted point angle, and a micrograin carbide grade that delivers consistent performance in demanding environments. The straight-cylindrical shank and web-thinned geometry reduce entry force and improve chip evacuation. It is sized and built for use in CNC machining centers, drill presses, and screw machine setups where a short, rigid drill is needed for accurate, repeatable hole placement.

This drill bit is suited for general-purpose drilling in aluminum and similar non-ferrous workpiece materials. Its stub length format provides added rigidity compared to jobber-length bits, making it a reliable choice when drilling close-tolerance holes in production environments. The bright/uncoated finish is appropriate for aluminum where coatings can contribute to built-up edge. Machinists, toolroom technicians, and CNC operators working in light manufacturing, aerospace, and fabrication shops are the primary users of this tool.

Key Features

• Solid micrograin carbide construction for wear resistance and dimensional stability
• 118-degree faceted point with web thinning for reduced thrust and cleaner entry
• Stub length design increases rigidity and minimizes deflection during drilling
• Right-hand spiral flute configuration promotes efficient chip removal
• Bright/uncoated finish optimized for aluminum and non-ferrous materials
• Manufactured to DIN 6539 specification with h8 diameter tolerance

Compatibility

Designed as a general-purpose stub-length carbide drill bit conforming to DIN 6539, suitable for use in standard straight-shank drill chucks and collet holders accepting a 5.11 mm shank diameter.

Installation Notes

Installation should be performed by qualified machinists or toolroom technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Secure the straight-cylindrical shank fully within the chuck or collet to the recommended grip depth to prevent pullout. Follow applicable shop safety procedures and machine manufacturer guidelines when setting speeds and feeds for carbide tooling in aluminum.
