Kennametal 4048727 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The KENNAMETAL 4048727 is a solid carbide corner radius end mill designed for demanding material removal in steel, stainless steel, cast iron, and hard materials. Carrying a 1/2-inch mill diameter and a 1/8-inch (0.1200 inch) corner radius, this single-end tool operates in the UCDE series and is suited for both roughing and finishing operations. The AlTiN PVD coating supports high-temperature cutting environments and extends tool life in abrasive workpiece materials. With five flutes and a high helix style, it maintains good chip evacuation and surface finish across a range of cutting conditions. The Weldon flat shank provides positive retention in standard toolholders.

This end mill is intended for use in CNC machining centers and milling applications where corner radius geometry is required to reduce stress concentrations at the base of a cut. It is compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems as noted by the manufacturer. Typical applications include profiling, slotting, and contour milling in ferrous and hard-material workpieces found in aerospace, die-mold, and general metalworking environments. Licensed machinists and CNC operators in production and job-shop settings are the primary installers of this tooling.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for high-temperature cutting in steel, stainless steel, and cast iron
• 1/8-inch corner radius reduces corner chipping and stress concentration in the workpiece
• Five-flute configuration with high helix style supports efficient chip flow and surface finish
• Weldon flat shank provides positive drive and secure retention in collet and end mill holders
• Single-end, right-hand cut and right-hand flute direction; not center-cutting

Compatibility

Designed for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems per manufacturer specification. Intended for machining steel, stainless steel, cast iron, and hard materials (material codes P, M, K, H).

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat shank fully into the holder and engage the set screw against the flat to prevent axial pullout. Verify runout with a dial indicator before initiating a cut, and confirm that cutting parameters match the material grade and coating specification provided by the manufacturer.
