Kennametal 4079274 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The KENNAMETAL 4079274 is a solid carbide corner radius end mill designed for high-performance milling in demanding material applications. With a 1/2 inch cutting diameter, a 0.0600 inch corner radius, and four right-hand spiral flutes, it delivers both roughing and finishing capability in a single tool. The AlTiN PVD coating provides thermal resistance and wear protection at elevated cutting temperatures. A 38-degree high helix angle promotes efficient chip evacuation and reduces cutting forces. This tool is installed by CNC machinists and tool-and-die professionals running vertical or horizontal machining centers.

This end mill is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials in both roughing and finishing operations. The 1-1/4 inch length of cut and 3 inch overall length support extended-reach applications where toolholder clearance is limited. The straight-cylindrical 1/2 inch shank fits standard end mill toolholders. It is a single-end, centercutting design, enabling both plunge entry and lateral passes. The series UADE designation identifies it within the KENNAMETAL extended-reach solid carbide end mill family.

Key Features

• 0.0600 inch corner radius reduces stress concentration and extends tool life on hardened and abrasive materials
• AlTiN PVD coating provides high-temperature oxidation resistance for dry and semi-dry cutting
• 38-degree high helix angle promotes aggressive chip evacuation in deep-cavity milling
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Extended-reach design with 1-1/4 inch LOC and 3 inch OAL for deeper pockets and cavities
• Submicron carbide grade substrate for improved hardness and edge retention in hard materials

Compatibility

Designed for use with standard end mill toolholders. Rated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H).

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Secure the shank fully within the toolholder to the recommended gauge-line depth before tightening — insufficient engagement increases runout and reduces tool life. Verify spindle and toolholder runout with a dial indicator before the first cut. Do not exceed the tool manufacturer's recommended cutting parameters for the specific workpiece material and machine spindle power.
