Kennametal 3660428 Corner Radius End Mill 0.5in 2 Flute Carbide

Product Description

The KENNAMETAL 3660428 is a solid carbide corner radius end mill designed for milling operations in non-ferrous metal applications. It features a 0.5-inch mill diameter, a 0.06-inch corner radius, and a 1.25-inch length of cut. The 3-inch overall length and straight cylindrical 0.5-inch shank make it compatible with standard end mill toolholders. With 2 flutes, a high helix angle of 45 degrees, and a coarse pitch, this end mill is configured for roughing material removal. It is single-ended, centercutting, and carries a bright uncoated finish. Licensed HVAC, machining, and metalworking professionals working with non-ferrous materials will find this part suited for high-volume stock removal passes.

This end mill is intended for use in non-ferrous metal machining environments, including aluminum, brass, copper, and similar materials. The ABDF series designation, submicron carbide grade, and right-hand flute and cutting direction make it a standard fit for CNC machining centers and manual milling setups where centercutting entry and corner radius profiles are required. It is sold as a single-end tool and is not configured for coolant-through delivery.

Key Features

• 0.06-inch corner radius for blended edge profiles in non-ferrous milling
• Solid carbide submicron grade construction for wear resistance and edge retention
• 2-flute, high helix (45 degrees) geometry optimized for chip evacuation in non-ferrous metals
• Centercutting design allows plunge entry without a pre-drilled hole
• Bright uncoated finish suited for applications where coating adhesion to workpiece is a concern
• Straight cylindrical shank compatible with standard end mill toolholders

Compatibility

Designed for use with standard end mill toolholders. Optimized for primary use in non-ferrous metal workpiece materials per series ABDF specifications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per standard shop safety procedures. Ensure the toolholder bore and shank diameter match before securing the tool to the specified clamping torque listed by the toolholder manufacturer. Verify runout with a dial indicator after mounting to confirm proper seating. Do not exceed the tool manufacturer recommended cutting parameters for the workpiece material and machine spindle.
