Kennametal 4067313 Corner Radius End Mill Head 1 in 4 Flute

Product Description

The KENNAMETAL 4067313 is a solid carbide corner radius end mill head designed for high-performance milling operations in demanding industrial environments. Part of the HARVI HPHV series, this single-end tool features a 1-inch mill diameter, a 2-inch length of cut, and 4 helical flutes with a 38-degree helix angle. The AlTiN coating provides thermal resistance and extended tool life when cutting ferrous and hard materials. The right-hand cutting and flute direction, combined with centercutting capability, make it suitable for slotting, profiling, and ramping operations. Weldon flat shank geometry ensures secure tool holding in compatible chucks and holders. This head is installed and operated by machinists and CNC tooling specialists in job shop and production environments.

This end mill head is suited for milling steel, stainless steel, cast iron, and hard materials in both roughing and finishing applications. The HPHV geometry is optimized for high productivity passes where heat generation and tool deflection are primary concerns. Typical install scenarios include CNC machining centers where modular tooling systems accept replaceable end mill heads, reducing changeover time and tooling costs on the shop floor. The regular length classification keeps the tool rigid under aggressive feed rates.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard material cutting
• AlTiN coating for high-temperature resistance and extended tool life
• 4 helical flutes with 38-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge entry into workpiece material
• Weldon flat shank for positive drive and reduced pullout risk in high-feed applications
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use in modular end mill head systems accepting a 1-inch Weldon flat shank. Compatible primary workpiece materials include steel, stainless steel, cast iron, and hard materials per material codes P, M, and K. Verify holder interface compatibility with your specific tooling system before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine fully powered down and the spindle locked before securing or removing the tool head. Confirm that the holder bore and Weldon flat setscrew engagement meet the tool manufacturer torque guidelines provided in your holder documentation. Inspect the cutting edges and coating for chips or damage before each use. Follow all applicable shop safety protocols and machine tool operating procedures during setup and operation.
