Kennametal 5351818 Corner Radius End Mill 1/2 in 6 Flute Altin

Product Description

The KENNAMETAL 5351818 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding materials. Built to the UJDE series specification, it features a 1/2 inch mill diameter, a 0.03 inch corner radius, and six helical flutes ground with a close pitch and high helix angle of 38 degrees. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting at elevated speeds. This single-end, centercutting tool is well suited for licensed machinists and toolroom professionals running CNC machining centers or manual mills with proper toolholding setups.

This end mill is intended for finishing cuts in steel, stainless steel, superalloys, titanium, and hard materials. Its 1-1/4 inch length of cut and 3 inch overall length make it practical for cavity work, profiling, and shoulder milling in both job shop and production environments. The straight cylindrical shank is compatible with standard end mill holders. The submicron carbide grade and AlTiN coating combination addresses the heat and abrasion demands common when machining high-strength alloys and hardened workpieces.

Key Features

• Solid carbide submicron grade construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating for elevated temperature resistance and extended tool life
• 6 helical flutes with close pitch and 38-degree high helix for efficient chip evacuation in finishing passes
• 0.03 inch corner radius reduces stress concentration at the cutting edge and improves surface finish
• Centercutting design allows plunge entry in addition to peripheral and slot milling
• Right-hand cut, right-hand flute configuration; no coolant-through, no chipbreaker, no variable helix

Compatibility

Rated for use in steel, stainless steel, superalloys, titanium, and hard materials (material codes P, M, S, H). Designed for use with standard end mill holders. Shank diameter is 1/2 inch with a straight cylindrical shank profile.

Installation Notes

Installation and tool changes must be performed by qualified machining professionals with the machine in a fully powered-down or e-stopped state. Seat the shank fully in the holder and torque the retention screw or collet nut according to the toolholder manufacturer specifications. Verify runout at the cutting edge before engaging the workpiece. Do not exceed the recommended depth of cut or feed rate for the workpiece material and machine spindle rating.
