Mitsubishi 10548585 Extra Length Carbide Drill Bit

Product Description

The MITSUBISHI 10548585 is a carbide extra length drill bit designed for high-performance deep hole drilling in demanding industrial and machining applications. Measuring 0.2087 inches (5.30 mm) in diameter with a 140-degree split point and X-thinning geometry, this bit delivers precise entry and reduced thrust across a wide range of workpiece materials. The TiAlN coating provides thermal resistance and extended tool life under high-speed cutting conditions. With an overall length of 6.1024 inches and a 3.9370-inch flute length, this MVS Series bit is engineered for machinists and tooling professionals working in production or job shop environments.

This drill bit is suited for deep hole drilling, cross hole drilling, stack drilling, and general drilling operations. Its coolant-through design supports chip evacuation and heat management at depth, making it effective in applications where tool life and hole quality are critical. Primary workpiece material is steel, with secondary suitability across stainless steel, superalloys, titanium, cast iron, hardened steel, carbon steel, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, structural steel, tempered steel, and iron.

Compatibility

Designed for use in deep hole drilling, cross hole, stack drilling, and standard drilling operations. Suitable for primary workpiece materials coded P (steel) and secondary materials coded P, M, K, and N per ISO specification designation. Part of the Mitsubishi MVS Series.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with CNC or manual drilling equipment. Power down and lock out the spindle before securing or removing the bit from the chuck or collet. Coolant-through capability requires a compatible machine spindle and coolant delivery system to function as intended. Always verify spindle speed and feed rate recommendations for the target workpiece material before commencing operation.
