Guhring 9006600002000 Micro Drill Bit Size 92 Cobalt

Product Description

The GUHRING 9006600002000 is a cobalt micro drill bit engineered for precision drilling in demanding production and machining environments. Sized at wire gauge 92 (0.0079 inches decimal equivalent), this bit features a 118-degree faceted point angle with web thinning for accurate entry and reduced thrust on small-diameter work. The titanium nitride (TiN) coating extends tool life by reducing friction and heat buildup at the cutting edge. Overall length is 0.984 inches, with a straight-cylindrical shank diameter of 1.00 millimeter. The spiral flute geometry follows DIN 1899 specification, and the right-hand cut suits standard drill press and CNC spindle setups used by machinists and toolroom technicians.

This micro drill bit is designed for drilling aluminum as its primary workpiece material, and is also rated for titanium alloy as a secondary application. The 5xD flute-to-diameter ratio and 1.50 mm flute length support maximum drilling depths up to 0.047 inches (1.20 mm), making this bit well suited for shallow, tight-tolerance bores in precision components, circuit board fixtures, mold work, and instrument manufacturing. It is part of the GUHRING Series 660 product line, which targets high-accuracy micro-drilling applications in both manual and CNC tooling setups.

Key Features

• Wire gauge size 92 with 0.0079 inch decimal equivalent for precision micro-bore work
• 118-degree faceted point with web thinning reduces walking and improves entry accuracy
• TiN coating lowers cutting friction and extends service life on abrasive and hard materials
• Cobalt construction provides heat resistance beyond standard high-speed steel
• DIN 1899 specification ensures dimensional consistency for interchangeable tooling programs
• Tapered web configuration supports chip clearance in shallow-depth drilling cycles

Compatibility

Designed as an OEM-style replacement or direct tooling addition for precision micro-drilling operations requiring a wire gauge 92, straight-cylindrical shank bit conforming to DIN 1899 standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Secure the straight-cylindrical shank in a collet or precision drill chuck rated for the 1.00 mm shank diameter before operation. Verify spindle runout is within tolerance before running micro-diameter tooling, as excess runout accelerates breakage at this diameter range. Follow shop safety procedures and applicable OSHA machine guarding standards when setting up drill press or CNC equipment.
