Kennametal 4046363 Corner Radius End Mill 10mm 4 Flute

Product Description

The KENNAMETAL 4046363 is a solid carbide corner radius end mill designed for high-performance milling in demanding metalworking applications. It features a 10 mm cutting diameter, a 1 mm corner radius, and four right-hand spiral flutes with a high helix angle of 38 degrees. The cutting edge is coated with AlTiN (aluminum titanium nitride) via a PVD process, providing heat resistance and extended tool life during aggressive cuts. With a 15 mm length of cut and an overall length of 76 mm, this single-end, center-cutting tool is built for both roughing and finishing passes in a single setup. Licensed machinists and CNC operators working in production environments are the primary users of this tool.

This end mill is suited for milling steel, stainless steel, cast iron, and hard materials in shop environments requiring tight tolerances and consistent surface finishes. The extended reach design, with a 30 mm reach length and a reduced neck diameter of 9.40 mm, allows access to deeper features and pockets without sacrificing rigidity. It is classified under the F4AS series and is intended for use with ER single angle standard collets. Applications span both roughing and finishing operations on ferrous and hard workpiece materials.

Key Features

• AlTiN PVD coating for high-heat resistance and extended tool life in ferrous and hard materials
• 1 mm corner radius reduces stress concentrations at the cutting edge and improves surface finish
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• Extended reach with 30 mm reach length and 9.40 mm neck diameter for deep-pocket access
• Submicron carbide grade for improved toughness and wear resistance
• Compatible with ER single angle standard collets for secure, repeatable clamping

Compatibility

Designed for use with ER single angle standard collets. Suitable for machining steel, stainless steel, cast iron, and hard materials. Material application codes P, M, K, and H apply.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a locked-out state. Ensure the collet and collet nut are clean and free of debris before seating the shank. Verify runout at the tool tip after clamping to confirm proper seating. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material being cut.
