Guhring 9006600015000 Cobalt Micro Drill Bit 0.0591 in

Product Description

The GUHRING 9006600015000 is a cobalt micro drill bit designed for precision drilling in small-diameter applications. Built to DIN 1899 standards, this bit features a 118-degree faceted point angle with web thinning for clean entry and reduced thrust. The TiN coating extends tool life by increasing surface hardness and reducing friction. At 0.0591 inches in diameter with a 1.181-inch overall length and a spiral flute design, this bit is suited for close-tolerance work in metalworking environments. Right-hand cutting direction and a straight-cylindrical shank make it compatible with standard drill chucks and collet holders. Licensed machinists and toolroom technicians are the primary users of this type of precision micro drill.

This drill bit is intended for use on aluminum as its primary workpiece material, with titanium alloy listed as a secondary application material. The Series 660 designation places it within a micro-drill family built for high-accuracy, small-diameter hole making in production machining, toolroom, and aerospace fabrication contexts. The 5xD flute-to-diameter ratio supports drilling depths up to 0.285 inches, making it appropriate for through-holes and blind holes in thin stock or precision components. Straight-cylindrical shank diameter is 2.00 millimeters, fitting standard micro-drill chucks and precision collets.

Key Features

• Cobalt construction provides heat resistance and durability in hard and abrasive materials
• TiN coating reduces friction and extends cutting edge life
• 118-degree faceted point with web thinning for accurate entry and reduced walking
• Right-hand spiral flute promotes efficient chip evacuation
• Tapered web configuration adds rigidity at the small diameter
• Conforms to DIN 1899 specification for consistent dimensional accuracy

Compatibility

Designed for use on aluminum (material code K, M, N, P) as the primary workpiece material and titanium alloy (material code S) as a secondary workpiece material. Fits standard micro-drill chucks and precision collets accepting a 2.00-millimeter straight-cylindrical shank.

Installation Notes

This tool is installed and operated by machinists using drill presses, CNC machining centers, or precision hand-held drilling equipment. Before tool changes, ensure the spindle is fully stopped and the machine is in a safe state. Use appropriate coolant or cutting fluid where permitted by machine setup, noting that this bit does not support coolant-through operation. Confirm chuck or collet runout is within tolerance before drilling to protect the small-diameter cutting edge from breakage.
