Kennametal 5052002 Corner Radius End Mill 0.5in 3 Flute Carbide

Product Description

The KENNAMETAL 5052002 is a solid carbide corner radius end mill designed for material removal in non-ferrous metal applications. It features a 0.5-inch mill diameter, a 1.5-inch length of cut, and a 0.06-inch corner radius that blends the cutting edge for improved surface finish and edge strength compared to a square end profile. The 3-flute, right-hand spiral geometry with a high helix style supports efficient chip evacuation. The bright uncoated finish makes it well suited for aluminum, copper, brass, and similar non-ferrous workpiece materials. CNC machinists and toolroom operators use this end mill for profiling, slotting, and roughing passes where corner radius geometry is specified.

This end mill fits standard straight-cylindrical end mill toolholders with a 0.5-inch bore. It is a single-end, centercutting tool, meaning it can plunge directly into the workpiece as well as cut on the periphery. The coarse pitch and 3-flute configuration make it appropriate for higher material removal rates in non-ferrous roughing operations on vertical machining centers, horizontal machining centers, and CNC knee mills. The 4-inch overall length gives adequate reach for most standard milling fixtures without sacrificing rigidity.

Key Features

• 0.06-inch corner radius reduces stress concentration at the cutting edge and improves workpiece surface finish
• Solid carbide submicron-grade construction provides hardness and wear resistance for non-ferrous cutting
• 3-flute right-hand spiral design with high helix style promotes chip evacuation in aluminum and soft metals
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Bright uncoated finish eliminates built-up edge risk when machining aluminum and other non-ferrous alloys
• Straight-cylindrical shank fits standard end mill toolholders and collet chucks with 0.5-inch bore

Compatibility

Designed for use with standard end mill toolholders accepting a 0.5-inch straight-cylindrical shank. Intended for non-ferrous metal workpiece materials as indicated by material application code N.

Installation Notes

Installation and tool changes must be performed with the machine spindle stopped and all motion fully arrested. Seat the shank fully into the toolholder or collet to the minimum engagement depth recommended by the toolholder manufacturer before torquing the retention mechanism. Inspect the corner radius and cutting edges for chips or damage before each use, as carbide end mills are brittle and should not be used if edge damage is visible. Follow the machine tool manufacturer and ANSI B11 series guidelines for speeds, feeds, and workholding when setting up milling operations.
