Kennametal 3580803 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The KENNAMETAL 3580803 is a solid carbide corner radius end mill designed for high-performance material removal in steel, superalloys, and titanium. It features a 0.5-inch mill diameter, a 0.03-inch corner radius, and five flutes with a high-helix, right-hand spiral configuration. The AlTiN PVD coating provides thermal resistance and extended tool life under demanding cutting conditions. With a 1.25-inch length of cut and a 3-inch overall length, this is a single-end tool built for both roughing and finishing operations. It is intended for use in professional CNC machining environments with standard end mill toolholders.

This end mill is suited for milling steel and high-temperature alloys including superalloys and titanium in production machining applications. The UDDE series geometry supports normal pitch cutting on CNC vertical and horizontal machining centers. A straight cylindrical shank with a 0.5-inch diameter fits standard collet and hydraulic toolholders. The tool is not center-cutting and does not support coolant-through capability, so it is best applied in applications where flood or mist coolant is delivered externally.

Key Features

• AlTiN PVD coating for high heat resistance and extended tool life in ferrous and exotic alloy machining
• Five-flute, high-helix spiral geometry for efficient chip evacuation and surface finish
• 0.03-inch corner radius reduces stress concentration and improves edge durability at workpiece corners
• Solid submicron carbide substrate for rigidity and wear resistance
• Designed for both roughing and finishing material removal in a single tool
• Straight cylindrical shank compatible with standard end mill toolholders

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece materials are steel, superalloys, and titanium (material codes P and S). Suited for CNC machining centers requiring a 0.5-inch shank diameter collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder bore and collet are clean and within tolerance before seating the shank. Verify spindle direction is set to right-hand rotation before engaging the cut. Do not use this tool for plunge cutting, as it is not center-cutting.
