Widin Carbide Square End Mill For Mold & Die - 4 Flute Variable - 8mm

Widin Carbide Square End Mill for Mold & Die — 8mm is a high-performance cutting tool designed for precision mold and die work. This 4‑flute end mill combines toughness with controlled geometry to deliver reliable, accurate results on demanding projects.

It offers a wide cutting diameter range from 0.8 mm to 25.0 mm and a tight diameter tolerance of +0 / -0.03 mm, ensuring repeatable features and minimal rework. The variable-index flute design uses a 29° helix on the first flute and 31° on the second, which helps reduce chatter and vibration while increasing tool life through smoother cutting and better chip evacuation. Crafted from premium carbide and finished with a W coating, it provides excellent wear resistance and stable performance in mold and die work.

• Variable-index flute geometry with two helix angles: Reduces chatter and vibration for smoother cuts, improved surface finish, and longer tool life in demanding mold and die applications.
• Wide diameter range with tight tolerance: Covers 0.8 mm to 25.0 mm cutting diameters with +0 / -0.03 mm accuracy for consistent, precise features across multiple tasks.
• Durable carbide with W coating: Delivers enhanced wear resistance and machining stability, helping the tool withstand hard steels used in mold and die work and extend service life.

This end mill supports efficient, repeatable performance in mold and die machining on materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel. By combining precise geometry, versatile sizing, and durable construction, it helps you finish complex molds faster, with fewer tool changes and less rework, while maintaining high-quality finishes across demanding projects.
