Mitsubishi 10516775 Micro Drill Bit 2.30mm Solid Carbide

Product Description

The MITSUBISHI 10516775 is a solid carbide micro drill bit designed for very small hole drilling in demanding production environments. Built to MVS Series specifications, it features a 145-degree drill point angle with X-thinning geometry that reduces thrust force and improves centering on entry. The TiAlN coating provides thermal resistance and extended tool life when cutting ferrous materials at elevated surface speeds. At 0.0906 inches (2.30 mm) in diameter with a 2.9291-inch overall length, this bit suits precision drilling operations where tight tolerances and consistent hole quality are required. Installation is performed by machinists and CNC operators working in metalworking and precision manufacturing applications.

This micro drill bit is rated for use in steel as its primary workpiece material. It is also suited for stainless steel, superalloys, titanium, hardened steel, copper, cast iron, carbon steel, brass, aluminum, and aluminum alloy applications. The right-hand cutting direction and straight-cylindrical shank make it compatible with standard drill chucks, collet holders, and CNC machining center spindles. Maximum drilling depth is 0.1969 inches (5.00 mm), and the 2xD flute-by-diameter ratio supports chip evacuation in shallow-to-moderate depth holes. This bit is appropriate for both manual and automated drilling cycles where micro-diameter accuracy is critical.

Key Features

• 2.30 mm (0.0906 inches) cutting diameter for very small hole drilling
• 145-degree drill point angle with X-thinning and parallel web configuration for reduced entry thrust
• TiAlN coating for heat resistance and extended tool life in ferrous and hard materials
• Coolant-through design supports internal coolant delivery for chip flushing and heat management
• Solid carbide construction provides rigidity and dimensional stability at small diameters
• Straight-cylindrical shank at 3.00 mm (0.1181 inches) diameter fits standard toolholding systems
• ISO-standard geometry; right-hand spiral fluting for reliable chip evacuation

Compatibility

Designed for use in steel, stainless steel, superalloys, titanium, hardened steel, copper, cast iron, carbon steel, brass, aluminum, and aluminum alloy workpieces. Fits standard straight-bore drill chucks and collet holders accepting a 3.00 mm shank diameter.

Installation Notes

This bit is intended for use by machinists and CNC technicians in controlled machining environments. Ensure the toolholder bore is clean and the shank is fully seated before tightening to eliminate runout. Verify spindle speed and feed rate are appropriate for the workpiece material and diameter before initiating a cut. Do not exceed the rated maximum drilling depth of 5.00 mm per pass without a peck-drilling cycle to clear chips and prevent bit deflection or breakage.
