Guhring 9064010016500 Micro Drill Bit 1.65mm Carbide

Product Description

The GUHRING 9064010016500 is a solid carbide micro drill bit designed for precision drilling in demanding industrial and machining applications. At 1.65 mm (0.0650 inches) in diameter, this bit features a 140-degree faceted point angle and a TiAlN (titanium aluminum nitride) coating that extends tool life in high-temperature cutting environments. The straight-cylindrical shank measures 3.00 mm and fits standard precision collet chucks. With an overall length of 52.00 mm and a flute length of 14.90 mm, this drill is built for controlled, accurate entry in tight-tolerance work. It is suited for use by machinists and tool-room technicians working with CNC machining centers, drill presses, and precision fixtures.

This micro drill bit is optimized for primary workpiece materials including cast iron, stainless steel, and steel (ISO material codes K, M, and P). Secondary applications include aluminum and titanium alloys (ISO codes N and S). The 7xD flute-to-diameter ratio supports deeper drilling relative to diameter, and the web-thinned, tapered web configuration reduces thrust force at entry. Maximum recommended drilling depth is 12.90 mm. This tool is intended for production and job-shop environments where small-diameter, high-precision holes are required across a range of metal workpieces.

Key Features

• Solid carbide construction from GUHRING material grade DK460UF for rigidity and wear resistance in micro-diameter tooling
• TiAlN coating improves heat resistance and extends tool life in ferrous and difficult-to-machine materials
• 140-degree faceted point angle reduces walking and improves entry accuracy on flat and curved surfaces
• Web-thinned, tapered web lowers thrust force and reduces the risk of drill deflection at small diameters
• Diameter tolerance of +0.002 to +0.012 mm supports tight-tolerance hole requirements
• Right-hand cutting direction with regular spiral flutes for standard chip evacuation in through and blind holes

Compatibility

Listed under GUHRING Series 6400 and 6401. Compatible with precision collet chucks and drill chucks accepting a 3.00 mm straight-cylindrical shank. Suitable for CNC machining centers and manual drill presses equipped for micro-diameter tooling.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with micro-diameter tooling practices. Ensure the spindle and collet are clean and properly torqued before seating the shank to prevent runout at small diameters. Coolant-through is not supported on this drill; external coolant or minimum quantity lubrication (MQL) should be applied per shop practice. Do not exceed the recommended maximum drilling depth of 12.90 mm without retracting to clear chips.
