Mitsubishi 10516973 Micro Drill Bit 2.30mm Carbide Tialn

Product Description

The MITSUBISHI 10516973 is a solid carbide micro drill bit designed for very small hole drilling in demanding machining applications. Built to MVS Series specifications, it features a 2.30 mm (0.0906 inch) cutting diameter, a 140-degree drill point angle with X-thinning geometry, and a TiAlN coating for extended tool life under high-heat conditions. The two-flute spiral design promotes efficient chip evacuation, and the coolant-through construction supports through-spindle coolant delivery. With an overall length of 74.40 mm (2.9291 inches) and a straight-cylindrical shank, this bit is suited for precision CNC drilling operations where tight tolerances and consistent hole quality are required.

This drill bit is intended for use in machining centers and CNC drilling operations targeting very small diameter holes. Its primary rated workpiece material is steel, and its secondary material compatibility covers stainless steel, superalloys, titanium, hardened steel, copper, cast iron, carbon steel, brass, aluminum, and aluminum alloy. The ISO-standard geometry and TiAlN coating make it a practical choice for production environments handling a range of ferrous and non-ferrous materials. Machinists and tool-room professionals working in aerospace, automotive, and precision manufacturing will find this bit suited to their high-speed, close-tolerance requirements.

Key Features

• Solid carbide construction for rigidity and wear resistance in micro drilling applications
• TiAlN coating extends tool life in high-temperature cutting conditions
• 140-degree drill point angle with X-thinning reduces thrust force and improves centering
• Coolant-through design supports internal coolant delivery for chip flushing and heat control
• Two-flute spiral geometry promotes efficient chip evacuation in deep holes
• Straight-cylindrical shank with 3.00 mm diameter for standard collet or chuck mounting

Compatibility

Designed for use in CNC machining centers and drill presses capable of accepting a 3.00 mm straight-cylindrical shank. Compatible with workpiece materials including steel, stainless steel, superalloys, titanium, hardened steel, copper, cast iron, carbon steel, brass, aluminum, and aluminum alloy per MVS Series ratings.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state. Verify collet or chuck bore matches the 3.00 mm shank diameter before seating the bit. Enable through-spindle coolant when the machine supports it to maximize chip clearing and tool life. Confirm maximum drilling depth does not exceed 16.50 mm (0.6496 inch) for this tool without adjusted feed and speed parameters.
