Kennametal 5351828 Corner Radius End Mill 0.5in 6 Flute

Product Description

The KENNAMETAL 5351828 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials including steel, stainless steel, superalloys, titanium, and hard materials. It carries a 0.03 inch corner radius, a 0.5 inch mill diameter, and six flutes arranged in a right-hand spiral with close pitch. The AlTiN PVD coating supports elevated cutting temperatures and extends tool life in abrasive and heat-resistant workpiece materials. At 4 inches overall length with a 1.25 inch length of cut, this tool is built for finishing passes where surface quality and dimensional accuracy matter. It is single-end and centercutting, allowing plunge entry where needed.

This end mill is suited for finishing applications on steel and stainless steel components, superalloys, titanium, and hard materials in both shop and production environments. The extended reach configuration, with a 2.25 inch reach length and a necked-down diameter of 0.47 inches, allows access to deeper features or stepped pockets without interference. The Safe-Lock shank type is compatible with HC-HSK Form A, HC-CV Form AD, and ER single angle standard collet toolholding systems. It is typically used by machinists and CNC operators running high-speed finishing programs on difficult-to-machine alloys.

Key Features

• AlTiN PVD coating for heat resistance and tool life in steel, stainless, superalloys, and hard materials
• Six-flute close-pitch geometry optimized for finishing and fine surface finish
• 0.03 inch corner radius reduces stress concentration at workpiece edges
• Extended reach design with 2.25 inch reach length and 0.47 inch neck diameter for deep-feature access
• Safe-Lock shank provides positive anti-pullout grip in compatible toolholders
• Centercutting construction permits plunge milling entry
• Submicron carbide grade for consistent edge integrity in hard and abrasive materials

Compatibility

Compatible with HC-HSK Form A, HC-CV Form AD, and ER single angle standard collet toolholding systems. Intended for use in applications involving steel, stainless steel, superalloys, titanium, and hard materials per workpiece material codes P, M, S, and H.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or carousel is in a safe state before mounting or removing the end mill. Use a torque wrench and follow the toolholder manufacturer specifications for collet nut or Safe-Lock setscrew tightening. Confirm runout with a dial indicator after mounting; excessive runout on a six-flute finishing tool accelerates uneven wear and degrades surface finish.
