Mitsubishi 662813 Extra Length Carbide Drill Bit 0.4531in

Product Description

The MITSUBISHI 662813 is a solid carbide extra length drill bit engineered for high-performance and high-precision drilling applications. It carries a TiAlN coating and measures 0.4531 inches (29/64 inch) in diameter with an overall length of 4.8860 inches. The helical, right-hand flute geometry runs 2.4450 inches and is paired with an X-Thinned web at a 140-degree drill point for improved chip evacuation and reduced thrust force. Coolant-through capability supports extended tool life in demanding production environments. This bit is sized in the MVS series with a parallel web configuration and cylindrical shank, making it well suited for machinists, tool-and-die professionals, and CNC operators working with tight-tolerance bores.

The 662813 is designed for cross hole drilling, standard drilling, and stack drilling operations. Its primary workpiece material designation is steel (ISO code P), with secondary material compatibility covering stainless steel, superalloys, titanium, structural steel, tempered steel, iron, high-strength bronze, hardened steel, copper, cast iron, carbon steel, bronze, brass, aluminum, and aluminum alloy. This range of material compatibility makes it a practical all-around bit for job shops and production floors handling mixed-material workflows.

Key Features

• Solid carbide construction with TiAlN finish for heat and wear resistance
• 140-degree drill point with X-Thinning for reduced entry thrust and cleaner hole starts
• Coolant-through design supports chip flushing and tool life in deep-hole and high-feed applications
• Helical right-hand flute, 2.4450 inches long, with 3xD flute-to-diameter ratio
• Cylindrical shank, 0.472 inches in diameter, with a shank length of 2.4410 inches
• Right-hand cutting direction; 2-flute configuration for balanced chip load
• Maximum drilling depth of 1.4420 inches

Compatibility

Designed for use in CNC machining centers, drill presses, and manual machine tools accepting a cylindrical shank. Suitable for cross hole, standard, and stack drilling operations across steel, stainless steel, aluminum, cast iron, brass, bronze, copper, and related alloys per ISO material codes P, M, K, and N.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC operator. Secure the cylindrical shank in a properly sized collet or drill chuck before operation and verify runout before beginning a cut. Activate coolant-through flow prior to engaging the workpiece when using through-coolant capability. Inspect the cutting edges for wear or chipping before each use, and replace the bit if edge integrity is compromised to avoid workpiece damage or tool breakage.
