Kennametal 6763960 Corner Radius End Mill 10mm 5 Flute Altin

Product Description

The KENNAMETAL 6763960 is a solid carbide corner radius end mill engineered for high-performance metal removal in demanding machining applications. Part of the KOR5 series, it features a 10 mm cutting diameter, a 0.5 mm corner radius, and five flutes with a high-helix spiral geometry. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting at elevated surface speeds. With a 30 mm length of cut and a 10 mm straight-cylindrical shank, this tool suits both roughing and finishing operations in a single setup. It is installed by machinists and CNC tooling specialists working in job shops, production facilities, and tool rooms.

This end mill is designed for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials — covering ISO material codes P, M, K, S, and H. Its coolant-through capability supports high-speed machining strategies where internal coolant delivery is available. The KOR5 series geometry is optimized for applications requiring tight corner tolerances and smooth surface finishes in difficult-to-machine alloys. It is compatible with ER single-angle standard collets and is supplied as a single-end tool.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for steel, stainless, cast iron, superalloys, titanium, and hard materials
• Five-flute, high-helix spiral design supports both roughing and finishing in one tool
• Coolant-through capability for heat management in deep-pocket and high-speed operations
• 0.5 mm corner radius reduces stress concentration and improves corner finish
• Right-hand cut, right-hand flute direction with normal pitch for predictable chip evacuation

Compatibility

Designed for use with ER single-angle standard collets. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials in CNC milling applications.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Verify spindle and collet runout before seating the shank to avoid premature edge wear. Ensure the tool is fully seated and torqued to the collet nut specification for the ER system in use. Confirm coolant-through lines are clear and delivering adequate flow before engaging a cut in hard or high-temperature alloys.
