Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 4mm x 8mm

The Widin Carbide Square End Mill is a precision cutting tool designed for mold and die work. Its square-end geometry delivers clean corners and precise features, helping you reproduce complex cavities and sharp edges with confidence.

Specifically built for demanding metals, it covers a wide cutting diameter range (1.0–20.0 mm) with tight tolerance and features a durable W coating that boosts wear resistance. The variable-index 4-flute design with dual helix angles reduces vibration and chatter, delivering stable cuts and longer tool life.

• Wide diameter range and precise tolerance: Covers 1.0–20.0 mm cutting diameters with a tight +0/−0.03 mm tolerance, enabling flexible work on multiple features without swapping tools.
• Variable index 4-flute with dual-helix angles: 29° and 31° helix angles reduce chatter, minimize resonance, and improve stability for smoother finishes and longer tool life on hard metals.
• Gash tooth design with W coating: Gash tooth reduces flute chipping and chattering; the W coating boosts wear resistance for long life when machining materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.

By delivering consistent pocketing, cleaner corners, and lower tool changes, this end mill helps you speed up mold and die projects. The robust carbide core with W coating keeps cutting forces stable, reduces downtime from tool wear, and delivers reliable, repeatable results even on tough steels. Whether you're prototyping or running production, you can trust the Widin end mill to perform with precision and durability across a range of materials.
