Guhring 9003010002600 Cobalt Micro Drill Bit 0.0102 in

Product Description

The GUHRING 9003010002600 is a cobalt micro drill bit designed for precision drilling in small-diameter applications. Built to DIN 1899 specification, this Series 301 bit carries a wire size of 86, equal to 0.0102 inches in decimal, and features a 118-degree faceted point with web thinning for accurate entry and reduced thrust. The overall length is 0.984 inches. The bright, uncoated cobalt construction provides heat resistance and edge retention when working through hard or abrasive workpiece materials. Right-hand spiral fluting efficiently clears chips from the cutting zone during operation.

This micro drill bit is suited for precision work in aluminum, titanium alloy, and similar materials in aerospace, machining, and manufacturing environments. The straight-cylindrical shank seats in standard collets and chucks without modification. With a flute-to-diameter ratio of 5xD and a tapered web configuration, it handles shallow, high-precision bores where dimensional accuracy is critical. Machinists and toolroom technicians working with micro-diameter holes in production or prototype settings will find this bit appropriate for those demands.

Key Features

• Wire size 86 (0.0102 inches) for micro-diameter drilling
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Cobalt tool material provides heat resistance and durability in hard materials
• Tapered web configuration with regular spiral fluting for efficient chip evacuation
• Straight-cylindrical shank with 1.00 mm diameter fits standard collets and chucks
• Conforms to DIN 1899 specification for consistent dimensional standards

Compatibility

Designed as a DIN 1899-compliant micro drill bit for use in CNC machining centers, drill presses, and precision hand tools equipped with collets or chucks accepting a 1.00 mm straight-cylindrical shank. Primary workpiece materials are aluminum and titanium alloy.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel. Secure the shank fully in the collet or chuck before operating spindle at rated speed. Micro drill bits are fragile at this diameter; avoid side loading, excessive feed pressure, or interrupted cuts that could cause breakage. Always follow machine manufacturer guidelines and applicable workplace safety standards when operating at micro-drilling speeds and feeds.
