Guhring 9064050020000 Micro Drill Bit 2mm Solid Carbide

Product Description

The GUHRING 9064050020000 is a solid carbide micro drill bit designed for precision drilling in demanding metalworking applications. Built to Series 6405 standards, it features a 2.00 mm diameter, a 140-degree faceted point angle, and a TiAlN coating that extends tool life in high-heat cutting conditions. The straight-cylindrical shank measures 4.00 mm in diameter, and the overall length is 56.00 mm with a 16.00 mm flute length and a maximum drilling depth of 13.60 mm. Coolant-through capability supports chip evacuation and thermal management during deep micro-drilling operations. This drill bit is installed by machinists and tool-and-die professionals working on precision components.

This drill bit is suited for use in CNC machining centers and precision drilling fixtures where tight tolerances and consistent hole quality are required. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary workpiece materials include aluminum and titanium alloy. The web-thinned design reduces entry force and improves centering accuracy in difficult-to-machine materials. The right-hand cutting direction and spiral flute geometry support standard CNC and manual drilling setups across a wide range of material grades.

Key Features

• Solid carbide construction, K40 material grade, for rigidity and wear resistance in hard materials
• TiAlN coating provides thermal and oxidation resistance at elevated cutting temperatures
• 140-degree faceted point angle with web-thinned tip reduces thrust force and improves hole entry
• Coolant-through design supports internal coolant delivery for chip flushing and heat control
• Flute-by-diameter ratio of 5xD with 13.60 mm maximum drilling depth for controlled micro-bore applications
• Diameter tolerance of m7 ensures consistent fit for precision bore applications

Compatibility

Designed for use with CNC machining centers and precision drilling equipment capable of accepting a 4.00 mm straight-cylindrical shank. Primary workpiece materials are cast iron, stainless steel, and steel; secondary materials include aluminum and titanium alloy.

Installation Notes

Installation and tool changes should be performed with the machine fully powered down and locked out per applicable safety procedures. Secure the straight-cylindrical shank in a compatible collet or drill chuck to the equipment manufacturer's specified clamping torque range. Verify coolant-through passages are clear before use if internal coolant is employed. Micro drill bits are brittle at small diameters — avoid side loading, improper feed rates, or running the tool in a worn or misaligned spindle.
