Guhring 9003010009100 Micro Drill Bit Wire 64 Cobalt

Product Description

The GUHRING 9003010009100 is a cobalt micro drill bit designed for precision drilling in demanding materials. Sized at wire gauge 64 (0.0358 inches diameter), it features a 118-degree faceted point with web thinning and a tapered web configuration for accurate starting and reduced thrust. The overall length is 0.984 inches with a spiral flute and a straight-cylindrical shank measuring 1.50 mm in diameter. Manufactured to DIN 1899 specification, this bit is built for right-hand cutting in a Flute-by-Diameter ratio of 5xD, making it well suited for high-precision micro-drilling operations in metalworking environments.

This drill bit is intended for use in precision machining applications where small-diameter, tight-tolerance holes are required. Primary workpiece material is aluminum, with secondary suitability for titanium alloys. The cobalt construction provides elevated heat resistance, making it appropriate for both production and toolroom settings where repeated cycling or harder alloys are encountered. It is typically installed in CNC machining centers, drill presses, or precision hand-held equipment by machinists and tool-and-die professionals.

Key Features

• Wire size 64 (0.0358 inches) diameter for micro-precision drilling
• Cobalt tool material for improved heat and wear resistance over standard HSS
• 118-degree faceted point with web thinning for accurate entry and reduced walking
• Spiral flute with tapered web configuration promotes chip evacuation in shallow holes
• Bright/uncoated finish suitable for aluminum and non-ferrous machining
• Conforms to DIN 1899 specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-fit micro drill bit for applications requiring wire gauge 64 tooling per DIN 1899 in straight-shank collet or chuck systems.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with micro-diameter tooling. Ensure the spindle and chuck or collet are clean and concentric before seating the straight shank to minimize runout. Micro drill bits are fragile at this diameter - secure workpieces firmly and use appropriate feed rates to avoid deflection or breakage. Disconnect power to any machine tool before changing tooling.
