Mitsubishi 662995 Extra Length Carbide Drill Bit 0.3320 in

Product Description

The MITSUBISHI 662995 is a carbide extra length drill bit designed for high-performance drilling in demanding metalworking applications. Measuring 0.3320 inches (8.43 mm) in diameter with a 140-degree drill point angle and a TiAlN coating, this bit delivers heat resistance and extended tool life in tough materials. The helical flute geometry and X-thinning point design reduce thrust load and improve chip evacuation. At 5.0600 inches overall length with a 2.7360-inch flute length, it handles deeper reach applications where standard-length bits fall short. Coolant-through capability supports high-feed operations in production environments. Licensed machinists, tool and die setters, and CNC operators are the primary users.

This drill bit is engineered for cross hole drilling, stack drilling, and general through-hole drilling operations. Its primary workpiece material classification is steel (ISO code P), with secondary suitability for stainless steel, superalloys, titanium, structural steel, tempered steel, hardened steel, cast iron, carbon steel, high strength bronze, copper, brass, aluminum, and aluminum alloys. The 5xD flute-to-diameter ratio makes it well suited for applications requiring extended reach beyond standard jobber lengths in both manual and CNC setups.

Key Features

• Carbide construction with TiAlN coating for heat resistance and extended wear life in ferrous and non-ferrous materials
• 140-degree drill point angle with X-thinning for reduced thrust and improved centering
• Coolant-through design supports high-speed production drilling and chip flushing in deep holes
• Helical flute with right-hand spiral and right-hand cutting direction for standard spindle use
• 5xD flute-by-diameter ratio provides extended reach for cross hole and stack drilling applications
• Cylindrical shank with 0.394-inch shank diameter fits standard drill chucks and collet holders

Compatibility

Part of the MITSUBISHI MVS series. Suitable for use in CNC machining centers and drill presses equipped with compatible collet or chuck toolholding systems. Designed for ISO P, M, and K workpiece material classifications including steel, stainless steel, cast iron, aluminum, and related alloys as specified in supplier documentation.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with cutting tool setup and safe machine operation. Verify that spindle speed, feed rate, and coolant flow are set per the machine tool and toolholder manufacturer specifications before engaging the cut. Secure the cylindrical shank in a properly sized collet or drill chuck and confirm runout is within acceptable tolerance before production use. Always power down the machine and follow lockout/tagout procedures before changing tooling.
