Kennametal 6767679 Corner Radius End Mill 3/4in 6 Flute

Product Description

The KENNAMETAL 6767679 is a solid carbide corner radius end mill engineered for high-performance metal removal in demanding machining environments. Built to KOR6 series specifications, it features a 3/4-inch mill diameter, a 0.06-inch corner radius, and six flutes with a close pitch configuration and high-helix spiral geometry. The AlTiN PVD coating provides heat resistance and extended tool life when cutting hard and abrasive materials. At 5 inches overall length with a 2.25-inch length of cut, this single-end, centercutting tool is suited for finishing passes where edge integrity and dimensional accuracy are critical.

This end mill is designed for right-hand cutting and right-hand flute direction. It accepts a Weldon flat shank at 3/4-inch diameter and is specified for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is classified for finishing-grade material removal and is compatible with ISO material categories P, M, K, S, and H. Coolant-through is not supported on this tool.

Key Features

• Solid carbide submicron-grade substrate for rigidity and wear resistance
• AlTiN PVD coating rated for steel, stainless, superalloys, and hard materials
• Six-flute close-pitch design optimized for finishing passes
• 0.06-inch corner radius reduces stress concentration at cutting edges
• Weldon flat shank for positive drive and reduced slippage in the holder
• Centercutting geometry allows plunge entry into the workpiece

Compatibility

Designed for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems as specified by the manufacturer. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H).

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout requirements. Confirm the Weldon flat is properly seated and engaged with the setscrew before operation. Verify spindle speed, feed rate, and depth of cut parameters against KENNAMETAL KOR6 series application data before use. Do not exceed the rated length of cut or use this tool for roughing passes beyond its finishing-grade designation.
