Mitsubishi 10542699 Carbide Drill Bit 0.2031 in 145 Deg

Product Description

The MITSUBISHI 10542699 is a solid carbide extra-length drill bit designed for high-performance and high-precision drilling in demanding industrial and metalworking applications. Measuring 0.2031 inches (13/64 inch) in diameter with a 145-degree drill point angle and a TiAlN coating, this bit delivers extended tool life and thermal resistance in tough materials. The flute length is 1.0550 inches and the overall length is 2.6300 inches. It features an X-thinned web point for reduced thrust and improved chip evacuation, and is built with coolant-through capability to support high-speed production environments. It is part of the Mitsubishi MVS series.

This drill bit is suited for cross hole drilling, stack drilling, and standard through-drilling operations on steel, stainless steel, cast iron, aluminum, brass, bronze, copper, carbon steel, tempered steel, hardened steel, high strength bronze, structural steel, superalloys, and titanium. The cylindrical shank diameter is 0.236 inches with a shank length of 1.4960 inches. Right-hand cut with a helical, right-hand spiral flute and a parallel web configuration, it is appropriate for CNC machining centers and precision drilling equipment in production and job-shop settings.

Key Features

• Solid carbide construction with TiAlN coating for heat and wear resistance
• 145-degree drill point angle with X-thinned web for reduced entry thrust
• Coolant-through design supports high-speed and deep-hole drilling
• Helical right-hand flute with parallel web configuration for consistent chip flow
• 2-flute design optimized for precision and surface finish
• Maximum drilling depth of 0.4370 inches; 2xD flute-by-diameter ratio

Compatibility

Part of the Mitsubishi MVS series, this drill bit is designed for use with materials coded P, M, K, and N per ISO designation, covering steel, stainless steel, cast iron, non-ferrous metals, and their alloys. Suitable for CNC drilling applications requiring high precision and high performance.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle and tool holder are clean and free of debris before seating the cylindrical shank. Verify that coolant supply lines are active and properly directed when using the coolant-through feature. Follow the machine manufacturer's recommended feed and speed parameters for the workpiece material being drilled.
