Guhring 9003010001700 Micro Drill Bit Wire 95 Cobalt

Product Description

The GUHRING 9003010001700 is a cobalt micro drill bit designed for precision drilling in small-diameter applications. Built to DIN 1899 standards, it carries a wire gauge size of 95, which corresponds to 0.0067 inches in decimal, making it one of the finer drill sizes available for close-tolerance work. The 118-degree faceted point with web thinning promotes accurate entry and reduces thrust force. The bright, uncoated cobalt construction provides heat resistance without added coating thickness, keeping the finished hole diameter consistent. This bit is suited to tool-and-die shops, precision machining environments, and specialty fabrication work where exact hole sizing at micro scale is required.

This drill bit is rated for aluminum as its primary workpiece material and titanium alloy as a secondary application. With an overall length of 0.984 inches and a 1.10 mm flute length, it is configured for shallow-depth micro drilling with a maximum drilling depth of 0.033 inches. The straight-cylindrical shank measures 1.00 mm in diameter and seats cleanly in compatible collet chucks or micro drill presses. The 5xD flute-to-diameter ratio and regular spiral flute geometry provide consistent chip evacuation for these tight bore applications. It ships individually but carries a minimum order quantity of 10 units per order.

Key Features

• Wire size 95 (0.0067 inches decimal) for fine-tolerance micro drilling
• 118-degree faceted point with web thinning reduces entry thrust and improves accuracy
• Cobalt tool material with bright, uncoated finish for dimensional consistency
• Right-hand cutting spiral flute with tapered web configuration for controlled chip flow
• Straight-cylindrical shank at 1.00 mm fits standard micro collet systems
• Manufactured to DIN 1899 specification for dimensional conformance

Compatibility

Designed as an OEM-style micro drill bit replacement for Series 301 tooling applications requiring a wire size 95, 1.00 mm shank, straight-cylindrical configuration per DIN 1899.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with micro drill handling. Secure the shank fully in a matched collet or chuck before operation and verify runout is within acceptable tolerance before drilling. Do not exceed the rated maximum drilling depth of 0.033 inches per pass. Use appropriate cutting fluid or coolant for the workpiece material even though this bit does not support through-coolant delivery.
