Iscar 3401349 Square End Mill 1 in 4 Flute Solid Carbide

Product Description

The ISCAR 3401349 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 1-inch mill diameter and a 2-inch length of cut, it handles slotting, profiling, and peripheral milling in a wide range of ferrous and non-ferrous materials. The 4-flute, right-hand spiral geometry delivers efficient chip evacuation and surface finish quality. A TiAlCN coating improves heat resistance and extends tool life in demanding cutting conditions. This end mill is intended for use by machinists and tooling professionals operating CNC or manual milling equipment.

This end mill suits job shops, production machining facilities, and maintenance departments performing precision metal removal. Its 38-degree helix angle promotes smooth cutting action and reduces chatter during side milling and full-slot operations. The variable index design helps suppress vibration for improved finish consistency. With a 1-inch shank diameter and 4.5-inch overall length, it fits standard R8, CAT, BT, and HSK toolholders commonly found in vertical and horizontal machining centers.

Key Features

• 1-inch mill diameter with 2-inch length of cut for deep profiling and slotting
• Solid carbide submicron-grade construction for rigidity and wear resistance
• TiAlCN coating for elevated temperature performance and extended tool life
• 38-degree helix angle for smooth chip flow and reduced cutting forces
• Variable index flute spacing to minimize vibration and improve surface finish
• Center-cutting capable, allowing plunge entry into workpiece material

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 1-inch bore milling toolholders on CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tooling setup personnel. Power down and lock out the machine spindle before changing tooling. Seat the shank fully in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.
