Kennametal 4067279 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The KENNAMETAL 4067279 is a solid carbide corner radius end mill designed for demanding metal removal in steel, stainless steel, cast iron, and hard materials. It carries a 3/4 inch mill diameter with a 0.12 inch corner radius, a 1-1/2 inch length of cut, and a 4 inch overall length. The AlTiN PVD coating provides thermal resistance and wear protection suited for high-speed and hard-material applications. With four flutes, a high helix style, a Weldon flat shank, and center-cutting geometry, this tool handles both roughing and finishing operations. Submicron carbide grade construction supports consistent performance under aggressive feed and speed conditions.

This end mill fits single-end toolholding setups and is rated for use in steel, stainless steel, cast iron, and hard workpiece materials designated under material codes P, M, K, and H. The Weldon flat shank and extended reach geometry make it well suited for deep-pocket milling, profiling, and contour work where rigidity and chip evacuation are priorities. Compatible toolholding systems listed in the input include EM-CV Form AD and EM IN-HSK Form A holders. The short length-type classification and right-hand cutting direction are standard for conventional CNC machining center setups.

Key Features

• Solid carbide submicron grade construction for strength and edge retention in hard materials
• AlTiN PVD coating for heat resistance and extended tool life in ferrous and hard-material cuts
• 0.12 inch corner radius reduces stress concentration and extends workpiece edge life
• Center-cutting geometry allows direct plunge entry into the workpiece
• Weldon flat shank provides positive grip and prevents pullout under heavy loads
• Rated for both roughing and finishing material removal in a single tool

Compatibility

Compatible toolholding systems per input data: EM-CV Form AD and EM IN-HSK Form A. Primary workpiece materials are steel, stainless steel, cast iron, and hard materials (material codes P, M, K, H). Part of the KENNAMETAL HPHV series.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and power is isolated before changing tooling. Seat the Weldon flat shank fully into the holder before tightening the set screw to the holder manufacturer specification. Verify runout with a dial indicator after installation and before cutting to confirm proper seating.
