Kennametal 6086576 Square End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The KENNAMETAL 6086576 is a solid carbide square end mill designed for precision milling in ferrous materials including steel, stainless steel, and cast iron. The 0.25-inch cutting diameter pairs with a 0.5-inch length of cut and a 30-degree helix angle to deliver efficient chip evacuation and clean edge geometry on demanding workpiece materials. The TiAlN coating provides thermal resistance and wear protection during high-temperature cutting passes. This is a single-end, center-cutting tool, meaning it can be used for plunge entry as well as peripheral and slot milling operations. It is suited for use in CNC machining centers and manual mills where tight tolerances and surface finish quality are required.

This end mill is designed for shop floor and production use in applications involving steel, stainless steel, and cast iron workpieces. It is well-suited for slotting, profiling, and pocketing operations in both job shop and production environments. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling passes. The 0.25-inch shank diameter fits standard collet chucks and end mill holders commonly used in CNC and manual milling setups.

Key Features

• TiAlN coating for elevated thermal and wear resistance in ferrous machining
• 30-degree helix angle promotes smooth cutting action and effective chip removal
• Center-cutting geometry allows direct plunge entry without a pre-drilled hole
• Solid carbide construction provides rigidity and dimensional stability under load
• 4-flute design balances material removal rate with surface finish quality
• Right-hand cut and right-hand flute configuration for standard milling operations

Compatibility

Rated for primary use on steel, stainless steel, and cast iron workpieces per material grade KC633M in the 4SE.IS-R-L-X series. Compatible with standard 0.25-inch collet chucks and end mill holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Ensure the collet or end mill holder is clean and free of debris before seating the shank to the full grip depth. Verify runout with a dial indicator after clamping, as excessive runout accelerates tool wear and degrades surface finish. Follow machine manufacturer guidelines and applicable shop safety procedures when setting speeds and feeds for carbide tooling.
