Guhring 9003010005300 Micro Drill Bit Wire 75 Cobalt

Product Description

The GUHRING 9003010005300 is a cobalt micro drill bit designed for precision drilling in demanding materials. Built to DIN 1899 standards, this Series 301 bit measures 0.984 inches in overall length with a wire gauge size of 75 (0.0209 inches decimal), making it suited for small-diameter, high-accuracy work. The 118-degree faceted point with web thinning reduces entry force and helps maintain positional accuracy on difficult surfaces. The tapered web configuration and bright uncoated finish are well-matched to applications where chip evacuation and dimensional control are priorities. HVAC, plumbing, and electrical tradespeople working with aluminum or titanium alloy components will find this bit appropriate for fixture drilling, panel work, and precision tapping prep.

This micro drill bit is intended for right-hand cutting operations in aluminum as its primary workpiece material, with titanium alloy as a secondary application. The spiral flute type and 5xD flute-to-diameter ratio support consistent chip removal at shallow depths. Maximum drilling depth is 0.103 inches (2.61 mm), making this bit appropriate for thin-stock and sheet material applications in both residential and light commercial trade environments. It ships individually (package quantity of 1) and is available in multiples of 10 per order.

Key Features

• Wire gauge size 75 (0.0209 inches decimal diameter) for tight-tolerance micro drilling
• 118-degree faceted point with web thinning for reduced entry force and accurate positioning
• Cobalt tool material for heat resistance in aluminum and titanium alloy cutting
• Straight-cylindrical shank with 1.00 mm shank diameter for standard chuck compatibility
• Bright/uncoated finish suitable for aluminum and non-ferrous workpieces
• Conforms to DIN 1899 specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-fit micro drill bit for applications conforming to DIN 1899 Series 301 standards, primarily in aluminum (material codes K, M, N, P) and titanium alloy (material code S) workpieces.

Installation Notes

Install this bit in a compatible drill press, CNC machine, or precision hand drill with a chuck rated for the 1.00 mm straight-cylindrical shank. Always power down or de-energize the drilling equipment before changing bits. Drill diameter tolerance is +0.000 to -0.004 mm, so verify chuck runout before use to maintain hole accuracy. At this diameter, low feed rates and appropriate cutting fluid for the workpiece material help prevent bit breakage.
