Guhring 9064000024500 Micro Drill Bit 2.45 Mm Carbide

Product Description

The GUHRING 9064000024500 is a solid carbide micro drill bit engineered for precision drilling in demanding metalworking applications. Built to Series 6400 specifications, it features a 2.45 mm diameter, a 140-degree faceted point, and a TiAlN coating that extends tool life in high-temperature cutting environments. The spiral flute geometry promotes chip evacuation, while the web-thinned point reduces entry force and improves centering accuracy. At 59 mm overall length with a 14.70 mm flute length and a 4.00 mm straight-cylindrical shank, this bit is sized for precision drilling operations where tight tolerances are required. It is installed and operated by machinists and toolroom technicians working on close-tolerance components.

This micro drill bit is suited for drilling cast iron, stainless steel, and steel as primary workpiece materials, with secondary suitability for aluminum and titanium alloys. The 4xD flute-to-diameter ratio and 11.70 mm maximum drilling depth make it appropriate for shallow precision holes in tight-tolerance machined parts. The right-hand cutting direction is standard for conventional CNC machining centers, drill presses, and manual milling setups. It is a practical choice in aerospace, automotive, die-and-mold, and general precision machining environments where micro-diameter accuracy is critical.

Key Features

• 2.45 mm diameter with m7 tolerance for tight dimensional control
• TiAlN coating provides heat and wear resistance in ferrous and hard-metal drilling
• 140-degree faceted point with web thinning reduces thrust force and improves hole entry accuracy
• Solid carbide K40 grade substrate delivers rigidity at micro diameters
• Straight-cylindrical 4.00 mm shank compatible with standard collet and chuck toolholding
• Right-hand spiral flute promotes efficient chip evacuation in short-depth holes

Compatibility

Designed for use with standard collet chucks and drill chucks accepting a 4.00 mm straight-cylindrical shank. Primary workpiece material compatibility includes cast iron, stainless steel, and steel; secondary compatibility includes aluminum and titanium alloys.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with micro-diameter tooling. Secure the shank fully in a collet or drill chuck rated for the spindle speed required by the workpiece material and diameter. At micro diameters, runout control is critical - use a precision collet chuck and verify runout before production drilling. Follow machine tool manufacturer guidelines and applicable shop safety procedures when handling carbide tooling.
