Kennametal 6086583 Square End Mill 5/16 in 4 Flute Carbide

Product Description

The KENNAMETAL 6086583 is a solid carbide square end mill designed for high-performance material removal in demanding machining environments. With a 5/16-inch mill diameter and 4-flute geometry, this single-end tool delivers efficient chip evacuation and a clean square shoulder profile. The 1/2-inch length of cut and 30-degree helix angle are well-suited for general-purpose milling, slotting, and profiling operations. A titanium aluminum nitride (TiAlN) coating from the KC633M material grade provides heat resistance and extended tool life when cutting ferrous and hard materials. The tool weighs 0.08 pounds and has an overall length of 2 inches.

This end mill is intended for use on steel, stainless steel, and cast iron workpieces, covering primary material codes P, M, and K. It is appropriate for CNC machining centers and manual mills where a right-hand cutting, right-hand spiral flute tool is required. The center-cutting capability allows plunge entry. Typical applications include finish profiling, side milling, and slot cutting in production and job-shop environments. It is part of the KENNAMETAL 4SE.IS-R-L-X series and is sold as a single-end tool in fractional inch sizing.

Key Features

• Solid carbide construction with KC633M material grade for rigidity and wear resistance
• TiAlN coating for elevated heat resistance during steel and stainless steel cuts
• 4-flute, right-hand spiral geometry with 30-degree helix for efficient chip flow
• Center-cutting design allows direct plunge entry into workpiece material
• 5/16-inch shank diameter matches mill diameter for straightforward collet setup
• Single-end tool with 1/2-inch length of cut and 2-inch overall length

Compatibility

Designed for machining steel, stainless steel, and cast iron. Suitable for use with standard 5/16-inch ER collets and compatible toolholding systems on CNC or manual milling machines. Part of the KENNAMETAL 4SE.IS-R-L-X series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked out per machine-specific procedures. Ensure the collet and toolholder are clean and free of chips before seating the shank. Verify runout after installation to protect both the tool and the workpiece. Follow the machine manufacturer and cutting tool manufacturer guidelines for feed rate and speed selection based on material and depth of cut.
