Kennametal 5351819 Corner Radius End Mill 1/2 Inch 6 Flute

Product Description

The KENNAMETAL 5351819 is a solid carbide corner radius end mill designed for high-performance finishing in demanding metalworking applications. With a 0.5 inch mill diameter, a 0.06 inch corner radius, and six flutes arranged in a right-hand spiral, this tool delivers smooth surface finishes and extended tool life in materials that punish lesser tooling. The AlTiN (aluminum titanium nitride) PVD coating provides heat resistance and hardness at the cutting edge, making it well-suited for dry or semi-dry machining. Close pitch and a high helix style contribute to efficient chip evacuation and reduced chatter during finishing passes. Licensed machinists and CNC operators working in production shops will recognize this as a purpose-built finishing tool for tight-tolerance work.

This end mill is engineered for finishing cuts in steel, stainless steel, superalloys, and titanium, as well as other hard materials. The centercutting geometry allows plunge entry, adding flexibility in complex setups. The straight cylindrical shank fits standard end mill toolholders, making it compatible with the widest range of spindle setups in both vertical and horizontal machining centers. It carries a standard length designation with a 1.25 inch length of cut and a 3 inch overall length, positioning it for general-purpose finishing work where reach and rigidity are balanced. The part is part of KENNAMETAL series UJDE.

Key Features

• Solid carbide submicron-grade construction for rigidity and edge retention in hard materials
• AlTiN PVD coating enhances heat and wear resistance for dry or semi-dry cutting
• Six flutes with close pitch and high helix for smooth finishes and chip evacuation
• Centercutting design allows direct plunge entry without a pilot hole
• 0.06 inch corner radius reduces stress concentration and extends tool and workpiece life
• Right-hand cutting and right-hand flute direction for standard spindle use

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece materials include steel, stainless steel, superalloys, titanium, and hard materials. Part of the KENNAMETAL UJDE series.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and machine is in a safe state before changing tooling. Verify toolholder bore size matches the 0.5 inch shank diameter and that runout is within acceptable limits before beginning a cut. Confirm feeds, speeds, and depth of cut are appropriate for the workpiece material and machine capability before engaging the tool.
