Kennametal 7077003 Corner Radius End Mill 6 Flute Altin

Product Description

The KENNAMETAL 7077003 is a solid carbide, single-end corner radius end mill designed for high-performance finishing in demanding materials. It carries a 0.5-inch cutting diameter, a 1-inch length of cut, and a 0.0300-inch corner radius. The 6-flute, close-pitch geometry paired with an AlTiN PVD coating supports extended tool life at elevated cutting speeds. The 38-degree high helix promotes efficient chip evacuation and stable cutting forces. This tool is suited for machinists and tool-and-die shops running finish passes on hard, abrasive, or heat-resistant workpiece materials.

The 7077003 belongs to KENNAMETAL series HA3A and is classified as a long-reach end mill with a 3-inch overall length and a straight cylindrical 0.5-inch shank. It is center-cutting, right-hand flute direction, and right-hand cutting. The tool is optimized for finishing operations in steel, stainless steel, superalloys, titanium, and hard materials. It is intended for use with standard end mill toolholders and is compatible with CNC milling centers and manual knee mills where close-tolerance corner profiling is required.

Key Features

• 6-flute close-pitch design supports smooth surface finish in finishing operations
• AlTiN PVD coating provides thermal resistance for cutting steel, stainless steel, superalloys, titanium, and hard materials
• 38-degree high helix angle promotes chip evacuation and reduces cutting forces
• Submicron solid carbide substrate delivers rigidity and wear resistance
• Center-cutting geometry allows plunge entry when required
• 0.0300-inch corner radius reduces stress concentrations at part corners and extends tool life

Compatibility

Designed for use with standard end mill toolholders. Suitable for CNC milling applications in steel, stainless steel, superalloys, titanium, and hard materials requiring close-tolerance corner radius finishing.

Installation Notes

Installation is performed by qualified machinists. Secure the straight cylindrical shank in a properly sized end mill holder or collet chuck and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before initiating cuts. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
