Kennametal 4046365 Corner Radius End Mill 10mm 4 Flute Carbide

Product Description

The KENNAMETAL 4046365 is a solid carbide corner radius end mill designed for high-performance milling in demanding metalworking applications. With a 10 mm cutting diameter, 3 mm corner radius, and 15 mm length of cut, this tool is built for both roughing and finishing operations in a single setup. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting ferrous and hard materials. Four right-hand spiral flutes with a high helix angle promote efficient chip evacuation, and the centercutting geometry allows plunge entry. The extended reach design with a 30 mm reach length and 9.40 mm neck diameter gives access to deeper features while maintaining rigidity.

This end mill is suited for machining steel, stainless steel, cast iron, and hard materials in CNC milling centers, machining cells, and tool room applications. The straight cylindrical shank is compatible with ER single angle standard collets for secure, concentric clamping. The short flute length-to-diameter ratio supports stable cutting in production environments where surface finish and dimensional accuracy are critical. It is appropriate for use by machinists and manufacturing engineers working with ISO material groups P, M, K, and H.

Key Features

• AlTiN PVD coating for heat resistance and extended tool life in hard and ferrous materials
• 3 mm corner radius reduces stress concentrations and improves surface finish at part edges
• Centercutting design enables plunge milling and ramp entry operations
• Extended reach with 30 mm reach length and 9.40 mm neck diameter for deep-feature access
• Submicron carbide grade substrate for toughness and wear resistance
• Compatible with ER single angle standard collets for repeatable runout control

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the collet and collet nut are clean and free of debris before mounting; verify runout with a dial indicator after clamping. Confirm machine spindle is fully stopped and locked out before tool changes. Follow the machine tool manufacturer guidelines and applicable shop safety procedures for cutting tool installation and speed and feed selection.
