Kennametal 7077023 Corner Radius End Mill 6 Flute Altin

Product Description

The KENNAMETAL 7077023 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding materials. It features a 0.5-inch diameter, a 2-inch length of cut, and a 0.0300-inch corner radius across six flutes. The AlTiN PVD coating provides heat and wear resistance, making this tool well-suited for dry or semi-dry cutting conditions at elevated surface speeds. It is a single-end, centercutting tool with a right-hand cut and right-hand flute direction, a high helix style, and close pitch geometry. Licensed machinists and toolroom professionals are the primary installers and operators.

This end mill is engineered for finishing passes on steel, stainless steel, superalloys, titanium, and hard materials. The HA3A series geometry and submicron carbide grade are selected for applications where edge life and surface finish consistency are critical. It is intended for use in standard end mill toolholders and is suited to CNC machining centers running close-tolerance finishing programs. The short flute-length classification and spiral flute type contribute to rigidity and reduced deflection in deep-reach finishing scenarios.

Key Features

• 0.0300-inch corner radius reduces stress concentrations at part edges and extends tool life in finishing cuts
• AlTiN PVD coating enhances performance in steel, stainless steel, superalloys, titanium, and hard materials
• Submicron carbide grade provides consistent edge integrity at high surface speeds
• Six-flute, close-pitch design increases feed rate capability during finishing operations
• High helix style improves chip evacuation and reduces cutting forces
• Centercutting capability allows direct plunge entry without a pre-drilled hole

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece materials are steel, stainless steel, superalloys, titanium, and hard materials as designated by material codes P, M, S, and H.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder is clean and within specified runout tolerance before seating the shank. Power down and lock out the spindle before changing or inspecting the tool. Verify that cutting parameters, including spindle speed and feed rate, are appropriate for the workpiece material and machine rigidity before initiating a cut.
