Guhring 9064000026000 Micro Drill Bit 2.6mm Solid Carbide

Product Description

The GUHRING 9064000026000 is a solid carbide micro drill bit designed for precision drilling in demanding materials. Built to Series 6400 standards, it features a 140-degree faceted point and a TiAlN (titanium aluminum nitride) coating that extends tool life in high-heat applications. The drill measures 2.6 mm in diameter with an overall length of 59 mm and a flute length of 15.6 mm. A web-thinned, tapered web configuration reduces entry force and helps center the drill accurately. The straight-cylindrical shank measures 4 mm in diameter, fitting standard collet chucks and drill chucks used in CNC machining centers and precision drilling operations.

This micro drill is suited for production and maintenance machining environments where tight tolerances are required. The 0.1024-inch (2.6 mm) diameter and a 4xD flute-to-diameter ratio support a maximum drilling depth of 12.4 mm. Primary workpiece materials include cast iron, stainless steel, and steel (ISO material codes K, M, and P). Secondary compatible materials include aluminum and titanium alloys (ISO codes N and S). Right-hand spiral flutes provide efficient chip evacuation during through and blind-hole drilling. This drill is well suited for tool-and-die, aerospace component, and precision manufacturing work.

Key Features

• Solid carbide construction in material grade DK460UF for rigidity and wear resistance in hard materials
• TiAlN coating improves heat resistance and extends tool life in steel and stainless steel applications
• 140-degree faceted point reduces thrust force and improves self-centering on entry
• Web-thinned, tapered web lowers cutting resistance and supports accurate hole positioning
• Right-hand spiral flutes promote reliable chip evacuation in blind and through holes
• Diameter tolerance of plus 0.002 to plus 0.012 mm supports close-tolerance hole requirements

Compatibility

Designed for use in CNC machining centers and precision drilling equipment with collet or chuck systems that accept a 4 mm straight-cylindrical shank. Primary workpiece materials are cast iron, stainless steel, and steel. Secondary workpiece materials include aluminum and titanium alloys.

Installation Notes

This drill bit is installed and serviced by machinists and CNC operators. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the collet or chuck. Verify runout and collet condition before use, as excessive runout will reduce tool life and hole accuracy. Do not exceed the recommended maximum drilling depth of 12.4 mm without confirming chip evacuation is adequate for the application.
