Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 1mm x 1mm

Widin Carbide Square End Mill for Mold & Die is a high-performance cutting tool designed for precision moldmaking and die work. It covers a broad cutting diameter range from 1.0 mm to 20.0 mm with a tight tolerance of +0/-0.03 mm, enabling accurate results across small slots and larger pockets. The square end geometry, paired with premium carbide, delivers clean, stable cuts in demanding applications.

Coated with a W coating and built on a durable carbide substrate, this end mill is engineered for wear resistance and long tool life. It can machine materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel, without sacrificing accuracy or surface finish.

• Variable-index four-flute design: Provides balanced, aggressive material removal with smoother cutting action across a wide range of diameters, helping extend tool life and reduce vibration.
• Dual-helix geometry for stability: Helix angles of 29° and 31° are staggered to dampen chatter and maintain cutting efficiency, delivering steadier cuts on mold features and die cavities.
• Gash tooth design with W coating: Gash tooth geometry helps prevent flute chipping, while the W coating enhances wear resistance and longevity when machining hard steels and alloys.

This end mill is designed to help you complete tight tolerances and fine finishes with fewer tool changes. The combination of a robust four-flute geometry, optimized helix angles, and the durable coating delivers reliable performance, improved stability, and consistent results across mold and die work—from small features to larger pockets—keeping your workflow efficient and productive.
