Guhring 9064050016000 Micro Drill Bit 1.60mm Carbide

Product Description

The GUHRING 9064050016000 is a solid carbide micro drill bit engineered for precision drilling in demanding materials. Built to Series 6405 specifications, it features a 1.60 mm (0.0630 inches) diameter with a TiAlN coating that extends tool life in high-heat cutting environments. The 140-degree faceted point angle promotes accurate entry and reduces walking on hardened or abrasive workpiece surfaces. With a straight-cylindrical shank measuring 4.00 mm in diameter and an overall length of 52.00 mm, this bit integrates into standard CNC and conventional drill setups used by machinists and tool-and-die professionals. Coolant-through design supports chip evacuation during deep micro-hole operations.

This drill bit is suited for precision machining applications in job shops, aerospace component manufacturing, and general metalworking environments. It performs in cast iron, stainless steel, and steel as primary workpiece materials, with secondary capability in aluminum and titanium alloys. The 5xD flute-to-diameter ratio and a maximum drilling depth of 11.00 mm make it appropriate for through-holes and blind holes in small, tight-tolerance parts. Right-hand cutting direction is standard for conventional spindle rotation setups.

Key Features

• Solid carbide construction, material grade K40, for rigidity and wear resistance in micro-diameter drilling
• TiAlN coating reduces thermal wear and extends tool life in ferrous and hard alloy materials
• 140-degree faceted point with web-thinned geometry for accurate entry and reduced thrust force
• Coolant-through design for effective chip evacuation and heat management at depth
• Straight-cylindrical 4.00 mm shank for compatibility with standard collet and chuck systems
• Right-hand spiral flute, regular spiral type, for consistent chip flow in supported materials

Compatibility

Designed for use in cast iron, stainless steel, and steel as primary workpiece materials, with secondary suitability for aluminum and titanium alloys. Primary workpiece material codes K, M, and P; secondary codes N and S per ISO classification.

Installation Notes

Installation and use should be performed by qualified machinists familiar with micro-diameter tooling. Ensure the spindle and workpiece are fully secured before engaging the drill to prevent bit deflection or breakage at this diameter. Verify coolant supply lines are clear and delivering flow before starting coolant-through operations. Micro drill bits are sensitive to runout — confirm collet or chuck concentricity with a dial indicator before production runs.
