Widia 5879223 Square End Mill 1/2 in 4 Flute Carbide

Product Description

The WIDIA 5879223 is a solid carbide square end mill designed for precision metal removal in demanding machining applications. Part of the I4S series, it features a 1/2-inch cutting diameter, a 3-inch length of cut, and a 4-flute helical geometry with a 30-degree helix angle. The bright/uncoated finish suits applications where coating interaction with workpiece materials is a concern. This end mill is sized for use in CNC machining centers and manual mills where rigidity and edge retention are critical. Machinists and toolroom professionals rely on solid carbide construction for longer tool life compared to high-speed steel alternatives.

The 5879223 is suited for cutting steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. The 6-inch overall length and straight cylindrical 1/2-inch shank fit directly into standard collets, end mill holders, and shrink-fit tooling systems. The centercutting capability allows for plunge entry as well as conventional peripheral and slot milling operations.

Key Features

• Solid carbide construction for high rigidity and edge retention in tough materials
• 4-flute helical design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows plunge, slot, and peripheral milling
• Right-hand cut and right-hand flute direction for standard CNC and manual mill setups
• Bright/uncoated finish compatible across a broad range of workpiece materials including superalloys and hard materials
• Straight cylindrical shank fits standard collets and end mill holders without modification

Compatibility

Designed as an OEM-style tooling solution for use in standard 1/2-inch toolholders, collet chucks, and shrink-fit systems on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use the appropriate collet or toolholder torque procedure per the toolholder manufacturer's guidelines. Verify runout with a dial indicator after clamping to confirm concentricity before beginning a cut.
