Kennametal 6086565 Square End Mill 9/64 Inch 4 Flute

Product Description

The KENNAMETAL 6086565 is a single-end, four-flute square end mill ground from solid carbide and coated with TiAlN for heat resistance and extended tool life. It carries a 9/64-inch (0.1406-inch) cutting diameter with a 9/16-inch length of cut and a 3/16-inch shank diameter, making it suited for precision slotting, profiling, and peripheral milling in tight-tolerance applications. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation while the TiAlN coating reduces friction and oxidation at elevated cutting temperatures. Licensed machinists and CNC operators working in job shop or production environments install this tool in standard end mill holders or collet chucks.

This end mill is designed for milling steel, stainless steel, and cast iron, covering ISO material groups P, M, and K. Its centercutting geometry allows direct plunge entry into a workpiece, expanding its usefulness for ramp, helical, and plunge operations. The 2-inch overall length keeps the tool compact and rigid, reducing deflection during aggressive side-milling passes. It is a practical choice for CNC machining centers and manual knee mills running tight feature work in ferrous materials.

Key Features

• Solid carbide construction in material grade KC633M for rigidity and wear resistance in ferrous cutting
• TiAlN coating reduces heat buildup and extends tool life when cutting steel and stainless steel
• Four right-hand spiral flutes at 30-degree helix angle for efficient chip evacuation and smooth surface finish
• Centercutting design permits plunge, ramp, and helical entry without a pre-drilled pilot hole
• Single-end configuration with 3/16-inch shank fits standard collet chucks and end mill holders
• No chipbreaker, no variable helix, no coolant-through — optimized for straightforward ferrous milling operations

Compatibility

Rated for primary use in steel, stainless steel, and cast iron (ISO P, M, and K material groups). Part of the KENNAMETAL 4SE.IS-R-L-X series. Designed for use in standard collet systems and end mill holders accepting a 3/16-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or quill is secured before inserting or removing the end mill. Seat the shank fully into the collet or holder to the recommended gauge-line depth and torque the retention mechanism to the toolholder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use; a damaged TiAlN coating indicates the tool should be replaced rather than rerun.
