Kennametal 4067268 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The KENNAMETAL 4067268 is a solid carbide corner radius end mill engineered for high-performance metal removal in demanding machining environments. Built to the HPHV series specification, it features a 5/8 inch cutting diameter, a 0.06 inch corner radius, and a 2.25 inch length of cut on a 5 inch overall length platform. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting ferrous and hard materials at elevated speeds. With a Weldon flat shank and right-hand flute spiral, it suits CNC milling setups requiring both roughing and finishing capability in a single tool pass.

This end mill is intended for use in steel, stainless steel, cast iron, and hard material applications in both roughing and finishing operations. The long-reach design and 2.25 inch reach length make it well suited for deep-cavity milling, shoulder milling, and contour work where standard-length tools cannot reach the workpiece. It is a single-end, center-cutting tool, making plunge entry possible. It is compatible with Kennametal toolholding systems including EM-CV Form AD and EM IN-HSK Form A holders.

Key Features

• 0.06 inch corner radius reduces stress concentration and improves edge life at workpiece transitions
• AlTiN PVD coating for high-temperature resistance when machining steel, stainless steel, and hard materials
• Submicron carbide grade substrate for toughness and wear resistance
• Long-reach extended geometry with 2.25 inch length of cut for deep-cavity access
• Weldon flat shank provides positive drive and prevents tool pullout under high feed loads
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand spiral with high helix style for efficient chip evacuation

Compatibility

Compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems. Designed for machining steel, stainless steel, cast iron, and hard materials in CNC milling applications requiring long-reach solid carbide tooling.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Secure the Weldon flat shank in a compatible holder torqued per the holder manufacturer specification before spindle startup. Confirm runout with a dial indicator before production cuts, as excessive runout accelerates corner wear on radius end mills. Always power down and lock out the spindle before changing or adjusting tooling.
