Kennametal 6086570 Square End Mill 3/16 in 4 Flute

Product Description

The KENNAMETAL 6086570 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 3/16 inch mill diameter and 4-flute spiral geometry at a 30-degree helix angle, it delivers efficient chip evacuation and a smooth finish on ferrous materials. The TiAlN coating provides thermal resistance and extended tool life in high-speed cutting conditions. The single-end configuration and right-hand cut with right-hand flute make it a standard choice for CNC machining centers and manual mills operated by machinists and tool-and-die professionals.

This end mill is suited for milling steel, stainless steel, and cast iron in both roughing and finishing passes. The centercutting design allows for direct plunge entry, making it versatile for slot milling, profiling, and pocket work. With a 3/4 inch length of cut and 2-1/2 inch overall length, it fits standard small-diameter toolholding setups where reach and rigidity are both priorities. The KC633M material grade and TiAlN finish are optimized for harder workpiece materials and elevated cutting speeds without coolant-through requirements.

Key Features

• Solid carbide construction in material grade KC633M for rigidity and wear resistance
• TiAlN coating for high-temperature performance and extended tool life on ferrous materials
• 4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute for standard CNC and manual mill spindle compatibility
• Single-end configuration with matched 3/16 inch shank and mill diameter for minimal runout

Compatibility

Designed for milling steel, stainless steel, and cast iron workpieces. Compatible with standard 3/16 inch collets and toolholders on CNC machining centers and manual vertical mills. Series 4SE.IS-R-L-X.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill toolholding and runout specifications. Seat the shank fully in the collet or toolholder and torque the retention hardware per the toolholder manufacturer specifications before operation. Verify spindle direction matches the right-hand cut orientation of this tool before engaging the workpiece. Coolant-through is not supported on this tool; apply flood or mist coolant externally as needed based on the material and feed conditions.
