Widin Carbide Square End Mill For Mold & Die - 4 Flute Variable - 6.5mm

The Widin Carbide Square End Mill for Mold & Die is a high-performance cutting tool designed to deliver precision in mold and die machining. With its square end and four-flute geometry, it handles pockets, slots, and contours with consistent accuracy.
This tool is built for versatility on steels commonly used in tooling, offering a broad cutting diameter range (0.8 mm to 25.0 mm) and a tight diameter tolerance to ensure repeatable results every time.

• Wide cutting diameter range with tight tolerance: Enables you to tackle a broad set of tasks—from fine pockets to larger cavities—without tool changes. It covers 0.8 mm to 25.0 mm diameters and maintains a +0/-0.03 mm tolerance for precise, repeatable cuts in mold and die components.
• Variable-index flutes with tuned helix angles: The staggered flute arrangement reduces chatter and resonance during cutting. With a 29° helix on the first flute and 31° on the second, it delivers smoother cuts, improved finish, and longer tool life in demanding materials.
• W-coated carbide for durability and stability: The premium W coating paired with high-wear resistant carbide enhances tool life and machining stability, especially on mold/die work below 55 HRc and on pre-hardened steel, alloy steel, and carbon steel.

This combination of range, stability, and coating means you can complete complex mold and die components with fewer tool changes, less rework, and more consistent results across batches. The Widin end mill supports faster setups, cleaner finishes, and longer tool life—helping you boost productivity and maintain high-quality tolerances across your toughest steel projects.
