Kennametal 6086584 Square End Mill 5/16 in 4 Flute Carbide

Product Description

The KENNAMETAL 6086584 is a solid carbide square end mill designed for precision milling in steel, stainless steel, and cast iron. It features a 5/16-inch cutting diameter, a 13/16-inch length of cut, and a 2-1/2-inch overall length. The 4-flute, single-end design with a 30-degree helix angle and spiral flute geometry promotes efficient chip evacuation and smooth cutting action. A TiAlN coating provides thermal resistance and extended tool life in demanding ferrous metal applications. The centercutting capability allows for direct plunge entry without a pilot hole.

This end mill is suited for general-purpose milling operations on CNC machining centers and manual knee mills. Typical applications include slotting, profiling, and shoulder milling in steel and stainless steel workpieces. The right-hand cut, right-hand flute configuration is standard for most vertical and horizontal milling setups. The KC633M material grade is engineered for performance in P, M, and K workpiece material categories as defined by ISO cutting material classification.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• TiAlN coating for elevated-temperature performance and extended tool life
• 4 spiral flutes with 30-degree helix angle for improved chip flow
• Centercutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute for standard milling spindle compatibility
• Single-end design; material grade KC633M in the 4SE.IS-R-L-X series

Compatibility

Designed as a direct-fit replacement end mill for standard 5/16-inch collets, end mill holders, and shrink-fit toolholders used in CNC and manual milling applications on steel, stainless steel, and cast iron workpieces.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked before changing tooling. Verify collet or holder bore matches the 5/16-inch shank diameter and that the tool is seated and torqued to the toolholder manufacturer's specification. Do not exceed the recommended depth of cut or feed rate for the workpiece material and tool diameter.
