Kennametal 6113086 Corner Radius End Mill 6 Flute Altin

Product Description

The KENNAMETAL 6113086 is a solid carbide corner radius end mill designed for finishing operations in demanding metalworking applications. Built on the UJDE series platform, it features a 0.5 inch mill diameter, a 0.03 inch corner radius, and six flutes with a high helix angle of 38 degrees. The AlTiN physical vapor deposition coating provides thermal and oxidation resistance, making this tool well suited for high-temperature cutting conditions. It is a single-end, centercutting design with right-hand flute direction and right-hand cutting direction. Machinists and tooling specialists in production environments rely on this geometry for consistent surface finishes and controlled corner blend on tight-tolerance features.

This end mill is engineered for finishing cuts in steel, stainless steel, superalloys, titanium, and hard materials. Its long-length configuration, with a 1.5 inch length of cut and 3.5 inch overall length, supports reach into deeper pockets and cavities where standard-length tools fall short. The close pitch, six-flute layout is optimized for light chip loads at higher surface speeds. It mounts directly into standard straight-bore end mill toolholders. This tool is intended for use in CNC machining centers handling aerospace, medical, energy, and precision industrial components where workpiece material hardness and heat generation are primary concerns.

Key Features

• 0.03 inch corner radius blends sharp corners to reduce stress concentration and improve tool life in hard materials
• Six-flute close pitch design supports high feed rates and superior surface finish in finishing passes
• AlTiN PVD coating provides oxidation resistance and hardness retention at elevated cutting temperatures
• Submicron solid carbide grade delivers rigidity and edge integrity in stainless steel, superalloys, and titanium
• 38-degree high helix angle promotes smooth chip evacuation and reduced radial cutting forces
• Centercutting geometry allows plunge entry and ramping operations without a pre-drilled pilot

Compatibility

Designed for use with standard straight-bore end mill toolholders. Suitable for machining steel, stainless steel, superalloys, titanium, and hard materials. Part of the KENNAMETAL UJDE series.

Installation Notes

Installation is performed by qualified machinists or CNC tooling setup personnel. Ensure the machine spindle is fully stopped and the tool path program is verified before mounting. Seat the 0.5 inch straight cylindrical shank fully in the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Confirm runout with a dial indicator before initiating any cutting cycle, particularly given the corner radius geometry which is sensitive to axial misalignment.
