Kennametal 3580867 Corner Radius End Mill Head 5 Flute

Product Description

The KENNAMETAL 3580867 is a solid carbide corner radius end mill head designed for high-performance milling in demanding metalworking applications. Measuring 0.375 inches in mill diameter with a 2.5-inch overall length, this single-end tool features five flutes with a right-hand cutting direction and a 0.030-inch corner radius. The AlTiN PVD coating provides thermal resistance and extended tool life across both roughing and finishing operations. It carries KENNAMETAL material grade KC643M and belongs to the UCDE series, making it a purpose-built solution for machinists and tooling technicians working in production and job-shop environments.

This end mill head is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The close pitch, variable index design helps reduce chatter and vibration during heavy material removal, while the center-cutting geometry allows plunge entry. Standard length construction and a straight-cylindrical shank at 0.375 inches diameter make it compatible with conventional toolholders used in CNC milling centers handling both roughing passes and finish contour work.

Key Features

• Solid carbide construction with AlTiN PVD coating for heat and wear resistance
• Five-flute, close-pitch variable index geometry reduces vibration during cuts
• 0.030-inch corner radius protects the cutting edge and improves surface finish
• Center-cutting capability allows direct plunge milling
• Right-hand spiral flutes with medium helix angle for balanced chip evacuation
• Rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO P, M, K, S, H)

Compatibility

Designed for use with standard toolholders accepting a 0.375-inch straight-cylindrical shank. Compatible toolholder fitment should be verified against shank diameter tolerance h6 and the specific toolholder specification. Part of the KENNAMETAL UCDE series; catalog number UCDE375J5BRB.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before seating or removing the end mill head. Verify toolholder bore cleanliness and confirm shank engagement depth meets toolholder manufacturer requirements before operation. Do not exceed the cutting parameters recommended for the material grade and coating classification.
