Kennametal 3580792 Corner Radius End Mill 1/2 in 5 Flute Altin

Product Description

The KENNAMETAL 3580792 is a solid carbide corner radius end mill designed for high-performance milling in steel, superalloys, and titanium. It features a 0.5 inch mill diameter, a 1.25 inch length of cut, and a 0.015 inch corner radius that reduces edge chipping and extends tool life in demanding applications. The AlTiN PVD coating provides thermal resistance and hardness, making it suitable for dry or semi-dry cutting at elevated temperatures. This is a single-end, right-hand cutting tool with a straight cylindrical shank and a high helix angle. It is installed by machinists and toolroom professionals in CNC machining centers using standard end mill toolholders.

This end mill is suited for both roughing and finishing operations on steel, superalloys, and titanium workpieces. The 5-flute geometry with normal pitch and spiral flute type supports chip evacuation while maintaining surface finish quality. It fits into standard end mill toolholders and is a strong choice for production environments where tool consistency and coating durability are priorities. The UDDE series designation identifies it within KENNAMETAL's submicron carbide grade lineup, optimized for difficult-to-machine materials in aerospace, die and mold, and general machining applications.

Key Features

• 0.015 inch corner radius reduces stress concentration and chipping at the cutting edge
• AlTiN PVD coating delivers high thermal hardness for steel and superalloy cutting
• 5-flute design balances material removal rate with chip clearance
• Submicron solid carbide grade provides rigidity and wear resistance
• High helix angle improves cutting action in tough materials
• Capable of both roughing and finishing in a single tool

Compatibility

Designed for use with standard end mill toolholders. Intended for machining steel, superalloys, and titanium. Compatible with CNC machining centers that accept straight cylindrical shank tooling at 0.5 inch shank diameter.

Installation Notes

Install in a clean, properly sized end mill toolholder and torque the retention mechanism to the toolholder specification before operation. Confirm runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear on carbide tools. Power down the spindle and lock out the machine before changing or inspecting the tool. Do not use this tool in a manual milling machine without adequate rigidity and spindle speed control.
