Kennametal 6086518 Square End Mill 3/4 in 4 Flute Carbide

Product Description

The KENNAMETAL 6086518 is a single-end, four-flute solid carbide square end mill designed for high-performance milling in ferrous and stainless materials. With a 3/4 inch cutting diameter, a 3 inch length of cut, and a TiAlN coating, this tool handles demanding cuts in steel, stainless steel, and cast iron where heat resistance and edge retention are critical. The 30-degree spiral flute geometry promotes efficient chip evacuation and reduced cutting forces. Machinists and tooling technicians working in job shops, maintenance facilities, or production environments will find this end mill suited for slotting, profiling, and peripheral milling operations.

This end mill is built for primary use in steel (P), stainless steel (M), and cast iron (K) workpiece materials, covering the most common ferrous alloy families encountered in CNC milling. The right-hand cut and right-hand flute configuration suits standard vertical and horizontal CNC machining centers. The centercutting design allows plunge entry in addition to conventional peripheral and slot milling, adding flexibility to the tool path. It carries the KC633M material grade designation within the KENNAMETAL 4SE.IS-R-L-X series and is supplied as a single unit with no extended reach or coolant-through features.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance in ferrous materials
• TiAlN coating provides high heat resistance and extended tool life in steel and stainless steel
• 30-degree helix spiral flute promotes smooth chip flow and reduced cutting forces
• Centercutting geometry enables direct plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute configuration for use on standard CNC machining centers
• Single-end design with matched 3/4 inch shank and cutting diameter for direct collet or end mill holder mounting

Compatibility

Designed for use in CNC machining centers and manual milling machines with standard 3/4 inch collets or end mill holders. Rated for primary workpiece materials including steel (P), stainless steel (M), and cast iron (K) per ISO material classification.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the spindle before inserting or removing the tool from any holder. Ensure the shank is fully seated and the holder is torqued to the machine manufacturer's specification using the appropriate collet nut wrench. Inspect the cutting edges for chips or wear before each use, as carbide tools can fail without visible warning if run past service life.
