Iscar 3401331 Square End Mill 0.75in 4 Flute Solid Carbide

Product Description

The ISCAR 3401331 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.75 inch cutting diameter and a 1.5 inch length of cut, this tool removes material efficiently across a range of workpiece materials. The submicron grain carbide substrate provides hardness and edge retention under demanding cutting conditions. A TiAlCN coating reduces heat buildup and extends tool life in dry or semi-dry machining. This end mill is installed and operated by machinists and CNC programmers working in job shops, production facilities, and tool rooms.

This end mill suits general-purpose and high-performance milling applications on machining centers and CNC mills. The centercutting geometry allows plunge entry directly into the workpiece. The 38-degree spiral flute helix promotes efficient chip evacuation and smooth cutting action. The variable index flute spacing reduces chatter and improves surface finish in slotting, profiling, and contouring operations on ferrous and non-ferrous metals.

Key Features

• Solid carbide construction with submicron grain substrate for hardness and wear resistance
• TiAlCN finish for thermal protection and extended tool life
• 4-flute, 38-degree spiral helix for efficient chip evacuation and reduced vibration
• Centercutting design allows direct plunge milling without pre-drilling
• Variable index flute spacing minimizes chatter in demanding cuts
• Right-hand cut, right-hand flute configuration for standard CNC mill spindle compatibility

Compatibility

Designed for use in standard 0.75 inch diameter end mill holders, collet chucks, and shrink-fit toolholders on CNC machining centers and manual mills. No specific model compatibility was stated in the product data.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and the machine in a safe, locked-out state. Secure the shank fully within the toolholder to the recommended grip depth before tightening. Verify runout with a dial indicator after installation to ensure concentricity. Consult the machine tool manufacturer guidelines and applicable shop safety standards before operation.
