Mitsubishi 663200 Extra Length Carbide Drill Bit 0.2570in

Product Description

The MITSUBISHI 663200 is a carbide extra length drill bit designed for precision drilling in demanding industrial and metalworking applications. The 663200 features a 0.2570-inch cutting diameter, a 140-degree split point with X-Thinning geometry, and a TiAlN coating that extends tool life under high-heat cutting conditions. With a flute-by-diameter ratio of 8xD and a maximum drilling depth of 2.1030 inches, this bit handles deep-hole work where standard-length tooling falls short. The helical flute design with right-hand spiral and right-hand cutting direction promotes efficient chip evacuation and reduces heat buildup during extended cuts. Licensed machinists, tool-and-die professionals, and precision drilling operations are the primary installers of this bit.

The MITSUBISHI 663200 is built for cross hole drilling, stack drilling, and standard through-hole drilling in production and job-shop environments. Its primary workpiece material designation is steel (ISO P), and it is rated for use across a broad range of secondary materials including stainless steel, superalloys, titanium, structural steel, tempered steel, hardened steel, iron, cast iron, carbon steel, high strength bronze, bronze, brass, copper, aluminum, and aluminum alloys. The cylindrical shank with a 0.315-inch shank diameter seats in standard collet and drill chuck toolholding systems. This bit is classified as high performance and high precision grade per Mitsubishi tooling designations.

Key Features

• 0.2570-inch cutting diameter with 140-degree X-Thinned split point for reduced thrust and accurate entry
• TiAlN coating improves heat resistance and extends tool life in ferrous and difficult-to-machine materials
• 8xD flute-by-diameter ratio enables deep-hole drilling up to 2.1030 inches maximum depth
• Coolant-through design delivers cutting fluid directly to the cutting edge for improved chip flushing and thermal control
• Helical right-hand flute with parallel web configuration promotes consistent chip evacuation and bore quality
• Cylindrical shank compatible with standard collet chucks and drill holders

Compatibility

Designed for use in CNC machining centers, drill presses, and similar machine tool setups where MVS-series extra length carbide drill bits are specified. Suitable for toolholding systems accepting a 0.315-inch cylindrical shank.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the cylindrical shank fully in the collet or drill chuck and verify runout with a dial indicator before production drilling. Follow the tool manufacturer's recommended speeds and feeds for the workpiece material being machined.
