Guhring 9006600010500 Micro Drill Bit 0.0413in Cobalt

Product Description

The GUHRING 9006600010500 is a cobalt micro drill bit designed for precision drilling in tight-tolerance applications. Built to DIN 1899 specification, it features a 118-degree faceted point with web thinning and a tapered web configuration that reduces entry force and improves centering accuracy. The TiN coating extends tool life in abrasive materials. At 0.0413 inches in diameter with a 0.984-inch overall length, this is a small-diameter, high-precision tool suited for machinists, toolroom technicians, and production line operators working with close-tolerance drilled features. The straight-cylindrical shank measures 1.50 mm in diameter for secure collet retention in standard micro-drill chucks.

This drill bit is primarily intended for use on aluminum and non-ferrous materials (material codes K, M, N, P) and is rated as a secondary option for titanium alloys (material code S). It is well suited to CNC machining centers, drill presses, and precision hand-held drilling equipment where small-diameter holes are required. The 5xD flute-to-diameter ratio and 6.80 mm flute length accommodate a maximum drilling depth of 0.206 inches (5.23 mm), making it appropriate for shallow, precise through-holes and blind holes in production and prototype environments.

Key Features

• Cobalt construction provides heat resistance and strength for hard and abrasive materials
• TiN coating reduces wear and improves surface finish in aluminum and non-ferrous workpieces
• 118-degree faceted point with web thinning improves self-centering and reduces drill wander at small diameters
• Tapered web configuration supports chip evacuation in spiral flute design
• Right-hand cut, straight-cylindrical shank compatible with standard collet-style micro-drill holders
• Built to DIN 1899 specification for dimensional consistency across production runs
• Diameter tolerance of +0.000 to -0.004 mm supports tight-tolerance hole requirements

Compatibility

Designed for use with standard collet chucks and micro-drill holders accepting a 1.50 mm straight-cylindrical shank. Primary workpiece materials are aluminum and non-ferrous metals; secondary workpiece material is titanium alloy. Part of the Guhring Series 660 micro-drill line built to DIN 1899.

Installation Notes

Secure the shank fully into the collet before engaging the spindle, and verify runout is within acceptable limits for the diameter being used. At 0.0413 inches, bit deflection and breakage risk increase significantly with side loading or misalignment, so ensure the workpiece is rigidly fixtured. Use appropriate cutting speeds and feeds for the workpiece material per the machine tool manufacturer and Guhring published parameters. Handle and store micro drill bits individually to prevent tip damage.
