Kennametal 4067281 Corner Radius End Mill Head 3/4in

Product Description

The KENNAMETAL 4067281 is a solid carbide corner radius end mill head designed for high-performance milling in demanding metal-cutting applications. Part of the HPHV series, it features a 3/4 inch mill diameter, a 0.030 inch corner radius, and four flutes with a right-hand cutting direction. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting steel, stainless steel, cast iron, and hard materials. At 4 inches overall length with a 1.625 inch length of cut, this single-end tool is built for both roughing and finishing passes. A Weldon flat shank ensures positive drive in compatible toolholders.

This end mill head is suited for milling operations on steel, stainless steel, non-ferrous metals, and hard materials in industrial machining environments. The variable index geometry and medium helix spiral flute design support chip evacuation and stable cutting across a range of workpiece materials. It is intended for use with compatible toolholders and is well-suited to CNC machining centers where consistent surface finish and material removal rate matter. The centercutting capability allows for plunge milling when required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material cutting
• AlTiN PVD coating rated for steel, stainless steel, cast iron, and hard materials
• 0.030 inch corner radius reduces stress concentration and extends tool life at corners
• Variable index flute geometry helps minimize chatter and vibration
• Centercutting design enables plunge entry without a pre-drilled hole
• Weldon flat shank provides positive engagement in standard toolholders

Compatibility

Designed for use with compatible toolholders accepting a 3/4 inch Weldon flat shank. Manufacturer catalog number HPHV750S4163R030 can be used to confirm fitment with KENNAMETAL HPHV series tooling systems.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and spindle locked. Torque the toolholder set screw to the toolholder manufacturer specification against the Weldon flat. Inspect the shank and toolholder bore for chips or damage before seating the tool. Verify runout with a dial indicator before initiating a cut.
