Guhring 9006600013500 Micro Drill Bit 0.0531 in Cobalt

Product Description

The GUHRING 9006600013500 is a cobalt micro drill bit designed for precision drilling in tight-tolerance applications. Built to DIN 1899 specification, it features a 0.0531-inch diameter, a 118-degree faceted point, and a TiN (titanium nitride) coating that extends tool life in demanding materials. The spiral flute geometry promotes chip evacuation, and the web-thinned, tapered web configuration reduces entry force at the cutting edge. Overall length is 0.984 inches with a 1.50 mm straight-cylindrical shank. This bit is suited for machinists, tooling technicians, and precision fabricators working with small-diameter holes in production or maintenance environments.

This micro drill bit is rated for primary use in aluminum and non-ferrous metals (material codes K, M, N, P) and secondary use in titanium alloys (material code S). The 5xD flute-to-diameter ratio and 0.294-inch maximum drilling depth make it appropriate for shallow, high-precision bores in CNC machining centers, drill presses, or similar setups where concentricity and hole quality are critical. It is sold individually but requires a minimum order quantity of 10 units.

Key Features

• 0.0531-inch cutting diameter with a tight tolerance of +0.000 to -0.004 mm
• 118-degree faceted point angle with web-thinned, tapered web for reduced thrust
• TiN coating for improved wear resistance and surface hardness
• Cobalt tool material handles elevated cutting temperatures in tough alloys
• Straight-cylindrical shank at 1.50 mm for secure collet or chuck retention
• Conforms to DIN 1899 specification for micro drill geometry

Compatibility

Designed as an OEM-specification micro drill bit per DIN 1899, suitable for use in standard 1.50 mm straight-shank collets and micro-drill chucks on CNC machining centers and precision drill presses.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with micro-diameter tooling. Ensure the spindle and collet are clean and properly torqued before seating the shank. At this diameter, runout control is critical — verify TIR with an indicator before drilling. Avoid side-loading or peck-drilling beyond the rated maximum depth of 0.294 inches to prevent breakage.
