Kennametal 6676485 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The KENNAMETAL 6676485 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. Built to the H1TE series specification, this single-end tool features a 3/8 inch diameter, a 0.015 inch corner radius, and four right-hand spiral flutes with a 36-degree helix angle. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting ferrous and hard materials at elevated speeds. A Weldon flat shank ensures positive drive and minimal runout in compatible toolholders. This end mill handles both roughing and finishing passes in a single setup.

This tool is suited for CNC machining centers and milling operations in job shops, production facilities, and tool rooms where steel, stainless steel, cast iron, superalloys, titanium, and hard materials are common workpiece materials. The centercutting design allows plunge entry, and the corner radius geometry reduces stress concentration at the cutting edge, extending edge life on abrasive materials. Compatible toolholder formats listed by the manufacturer include EM-CV Form AD and EM IN-HSK Form A holders.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance
• AlTiN PVD coating rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials
• 0.015 inch corner radius reduces edge chipping and improves surface finish at workpiece corners
• Centercutting design permits direct plunge milling without a pre-drilled entry hole
• 36-degree right-hand helix promotes efficient chip evacuation and smooth cutting action
• Weldon flat shank provides positive drive and resists pullout in high-feed applications

Compatibility

Designed for use with EM-CV Form AD and EM IN-HSK Form A toolholders as specified by the manufacturer. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials per KENNAMETAL H1TE series application guidelines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured to the rated torque specification of the toolholder manufacturer before operating. Inspect the Weldon flat engagement and setscrew condition prior to each use. Follow the toolholder manufacturer and machine tool OEM guidelines for runout tolerance and maximum overhang length.
