Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 8mm x 16mm

The Widin Carbide Square End Mill is a high-performance cutting tool designed specifically for mold and die machining. With a square end and a 4-flute, variable-index geometry, it delivers aggressive material removal while maintaining stable cutting. The tool supports cutting diameters from 1.0 mm to 20.0 mm with a tight tolerance of +0 / -0.03 mm, and it arrives in an 8 mm x 16 mm size for versatile, compact use in tight features.

Its alternating 29° and 31° helix angles help minimize chatter and vibration, extending tool life and delivering steadier cuts. The gash tooth design reduces flute chipping under heavy loads, boosting durability. A W coating further enhances wear resistance and longevity, enabling longer runs between changes. Crafted from premium carbide and engineered for materials below 55 HRc, as well as pre-hardened steel, alloy steel, and carbon steel, this end mill is prepared for demanding mold and die operations.

• Variable-index 4-Flute Design: Staggered flute spacing reduces chatter and vibration, delivering smoother cuts, longer tool life, and more consistent finishes on tough materials.
• Gash Tooth Geometry for Durability: Specially shaped teeth help prevent flute chipping during aggressive passes, improving reliability on high-load jobs.
• W Coated Carbide for Longevity: The protective coating and premium carbide construction reduce wear and friction, enabling longer tool life across a range of steels (including those below 55 HRc).

Using this end mill helps you maintain tighter tolerances, complete jobs faster, and achieve repeatable results across various mold and die applications. Its combination of strength, stability, and wear resistance supports efficient workflows from roughing through finishing, giving you confidence in every cut.
