Kennametal 6767730 Corner Radius End Mill 1 in 6 Flute KOR6

Product Description

The KENNAMETAL 6767730 is a solid carbide corner radius end mill engineered for high-performance milling in demanding material applications. Designed for the KOR6 series, this single-end, centercutting tool features a 1 inch cutting diameter, a 5 inch length of cut, and a 0.06 inch corner radius that reduces stress concentration at the cutting edge. The 6-flute configuration with a close pitch and high helix angle promotes efficient chip evacuation and surface finish quality. An AlTiN PVD coating delivers elevated heat resistance and wear protection, making this tool well-suited for aggressive finishing passes at elevated cutting speeds. Submicron carbide grade construction contributes to edge stability across extended production runs.

This end mill is designed for finishing operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is commonly used in aerospace, die and mold, and general machining environments where tool life and surface finish consistency are critical. The Weldon flat shank and 1 inch shank diameter allow secure clamping in standard end mill holders. Compatible toolholding systems listed in input data include EM-CV Form AD and EM IN-HSK Form A holders. The extra-long length of cut and 7.5 inch overall length support deep-pocket and long-reach milling applications where standard-length tooling cannot reach.

Key Features

• 1 inch cutting diameter with 0.06 inch corner radius for reduced edge chipping in hard materials
• 6 flutes with close pitch and high helix angle for improved surface finish and chip flow
• AlTiN PVD coating for thermal and wear resistance in steel, stainless, cast iron, superalloys, and hard materials
• Extra-long 5 inch length of cut enables deep-pocket and long-reach milling
• Centercutting design allows plunge entry capability
• Weldon flat shank provides positive anti-pullout engagement in standard toolholders
• Submicron carbide grade for edge stability and consistent performance in finishing operations

Compatibility

Compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems. Intended for use in finishing applications on 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 or CNC setup technician. Secure the Weldon flat shank in a matching end mill holder torqued to the toolholder manufacturer specification before spindle operation. Confirm runout with a dial indicator before beginning cuts, particularly given the extra-long reach of this tool. Always verify spindle direction is set to right-hand rotation to match the right-hand flute and cutting direction of this end mill.
