Kennametal 3660424 Roughing Finishing End Mill 3/8 in

Product Description

The KENNAMETAL 3660424 is a solid carbide roughing finishing end mill designed for aggressive material removal followed by a quality finish cut in a single tool. Built from micrograin solid carbide, it measures 3/8 inches in diameter with a 3/4 inch length of cut and a 2-1/2 inch overall length. The 38-degree helix angle promotes efficient chip evacuation, and the bright uncoated finish suits a wide range of workpiece materials. Machinists and tool and die professionals install this end mill in CNC machining centers and manual mills requiring a right-hand cutting, single-end tool with a straight shank.

This end mill fits standard applications in job shops, tool rooms, and production environments where a single tool must handle both roughing passes and finishing passes. The three-flute, square-end geometry with centercutting capability allows plunge entry and full slot milling. The regular-length, straight shank with a 3/8 inch shank diameter accommodates common collet and end mill holder systems. No extended reach is required for the typical workholding setups this tool is intended to serve.

Compatibility

Designed as an OEM-style solid carbide roughing finishing end mill for use in CNC machining centers and manual mills accepting a 3/8 inch straight shank with standard collets or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before mounting or removing any cutting tool. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use and discard any tool showing edge deterioration to avoid workpiece damage or tool breakage.
