Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 3mm x 8mm

The Widin Carbide Square End Mill is built for mold and die work, delivering precise, efficient cutting across a range of sizes. Its four-flute, square-end geometry and variable-index design minimize vibration, helping you achieve clean edges on hard steels and complex cavities.

With a cutting diameter range of 1.0 mm to 20.0 mm and a tight tolerance of +0/-0.03 mm, this end mill adapts to many workpieces while maintaining consistent accuracy. The tool features dual helix angles (29° and 31°) to reduce chatter, a gash tooth profile to prevent flute chipping, and a W coating that boosts wear resistance for demanding mold and die applications, including materials below 55 HRC, pre-hardened steel, alloy steel, and carbon steel.

• Variable-index four-flute design with dual helix angles: Reduces chatter and resonance for stable, smooth cutting, improving tool life and finish on challenging mold and die work.
• Gash tooth geometry for durability: Specifically crafted to prevent flute chipping, enhancing reliability and reducing downtime in tough cutting conditions.
• W-coated carbide for longevity: The coating improves wear resistance and heat tolerance, helping maintain sharpness and finish when machining hard alloys and steels.

This end mill is purpose-built to streamline mold and die workflows. By combining broad cutting range, tight dimensional control, and a robust coating, it delivers consistent performance across a variety of steels and pre-hardened materials, helping you finish jobs faster with fewer tool Changes and less rework.
