Widin Carbide Square End Mill For Mold & Die - 4 Flute Variable - 11mm

Introducing the Widin Carbide Square End Mill for Mold & Die - 4 Flute Variable - 11mm, a high-performance cutting tool designed for precision mold and die work. Its broad cutting diameter range from 0.8 mm to 25.0 mm lets you tackle a wide variety of features with a single tool, reducing tool changes and increasing setup efficiency.

Designed with a four-flute variable-index geometry, it uses a 29° helix on the first flute and 31° on the second to reduce chatter, improve finish, and extend tool life. The W coating enhances wear resistance and machining stability, enabling reliable performance in demanding materials such as pre-hardened steel, alloy steel, and carbon steel — particularly for mold and die machining below 55 HRc.

• Wide cutting diameter range: Covers from 0.8 mm to 25.0 mm, allowing a single tool to handle many finishing, profiling, and pocketing tasks without swapping tools.
• 4-flute variable-index design with dual-helix angles: Features a 29° first-flute and 31° second-flute to reduce chatter, improve surface finish, and extend tool life through smoother cutting forces.
• W-coated carbide for durability: The coating boosts wear resistance and machining stability, delivering longer tool life and consistent performance on mold/die steels and common pre-hardened, alloy, and carbon steels.

With a tight diameter tolerance of +0/-0.03 mm, this end mill delivers precise, repeatable cuts that help you maintain tight tolerances across complex mold and die components. The combination of versatile sizing, chatter-damping geometry, and durable coating supports faster cycles, fewer tool changes, and more reliable results in demanding machining workflows.
