Guhring 9006600003000 Micro Drill Bit 0.0118 in Cobalt

Product Description

The GUHRING 9006600003000 is a cobalt micro drill bit designed for precision drilling in demanding materials. Built to DIN 1899 standards, this bit features a 118-degree faceted point angle and a TiN (titanium nitride) coating that extends tool life in high-wear applications. The straight-cylindrical shank measures 1.00 mm in diameter, and the overall length is 0.984 inches. The spiral flute geometry follows a 5xD flute-to-diameter ratio, promoting chip evacuation in shallow, tight-tolerance bores. Licensed machinists and tool-and-die professionals reach for this series when micron-level accuracy is required in production environments.

This drill bit is rated for primary use in aluminum and non-ferrous materials (ISO material codes K, M, N, P) and is also suited for titanium alloy workpieces (ISO code S). The right-hand cut spiral flute and web-thinned, tapered web configuration make it appropriate for CNC machining centers, drill presses, and precision hand-held spindle applications where hole diameter tolerance must be held tight. Maximum drilling depth is 0.057 inches (1.45 mm), making it appropriate for shallow micro-bore applications in aerospace, electronics, and precision mechanical components.

Key Features

• Cobalt construction provides heat resistance and rigidity for hard and abrasive workpiece materials
• TiN coating reduces friction and increases surface hardness for extended tool life
• 118-degree faceted point angle with web-thinned, tapered web for accurate entry and reduced thrust
• Right-hand spiral flute promotes reliable chip evacuation in shallow micro-bore cuts
• DIN 1899 specification ensures dimensional consistency across the Series 660 product line
• Diameter tolerance of +0.000 to -0.004 mm supports tight-tolerance hole requirements

Compatibility

Designed as a Series 660 DIN 1899 micro drill bit rated for aluminum, non-ferrous metals (ISO codes K, M, N, P), and titanium alloys (ISO code S); confirm spindle collet or chuck accepts a 1.00 mm straight-cylindrical shank before installation.

Installation Notes

Installation and use should be performed by qualified machinists familiar with micro-tooling practices. Secure the straight-cylindrical shank in a precision collet or chuck rated for 1.00 mm shanks and verify runout before drilling. At this diameter, excessive feed pressure or misalignment will cause bit breakage; follow the machine manufacturer's recommended feed and speed parameters for the workpiece material. Ensure the workpiece is rigidly fixtured and the spindle is fully stopped before changing tooling.
