Guhring 9006600006000 Micro Drill Bit 0.0236in Cobalt

Product Description

The GUHRING 9006600006000 is a cobalt micro drill bit designed for precision drilling in demanding materials. Built to Series 660 specifications, it features a 118-degree faceted point angle with web thinning on a tapered web configuration, which reduces entry force and improves hole accuracy at small diameters. The bit carries a TiN (Titanium Nitride) coating to extend cutting edge life and reduce friction during drilling cycles. At 0.0236 inches in diameter and 0.984 inches overall length, this drill is suited for machinists, tool-and-die technicians, and precision fabricators working with tight-tolerance applications.

This micro drill bit is engineered primarily for use in aluminum and aluminum alloys, with secondary suitability for titanium alloys. Its straight-cylindrical shank at 1.00 mm diameter seats securely in standard collet chucks and precision drill chucks used on CNC machining centers, drill presses, and manual lathes. The 5xD flute-to-diameter ratio and 3.90 mm flute length allow chip evacuation in shallow-to-moderate depth holes up to 0.118 inches (3.00 mm) maximum drilling depth. Right-hand spiral flute geometry supports conventional clockwise cutting direction.

Key Features

• Cobalt construction with TiN coating for extended tool life in abrasive and high-strength materials
• 118-degree faceted point with web thinning reduces thrust force and improves centering accuracy
• Tapered web configuration supports rigidity at 0.0236 inches diameter
• Maximum drilling depth of 0.118 inches (3.00 mm) with a 5xD flute ratio for efficient chip clearance
• Straight-cylindrical shank compatible with standard collet and precision drill chuck toolholding
• Right-hand cut spiral flute for conventional CNC and manual machine operation

Compatibility

Designed for use in CNC machining centers, drill presses, and precision lathes equipped with collet chucks or precision drill chucks accepting a 1.00 mm straight-cylindrical shank. Primary workpiece materials are aluminum alloys (material code K, M, N, P); secondary application covers titanium alloys (material code S).

Installation Notes

This tool should be installed and operated by qualified machinists or precision fabricators familiar with micro-diameter tooling. Ensure the machine spindle and chuck are clean and free of runout before seating the shank, as concentricity is critical at sub-millimeter diameters. Power down and lock out the machine before changing tooling. Do not exceed the rated maximum drilling depth of 0.118 inches per pass without retracting to clear chips.
