Widin Carbide Square End Mill For Mold & Die - 4 Flute Variable - 20mm

Widin Carbide Square End Mill for Mold & Die is a high‑performance cutting tool designed for precision work in mold cavities and die components. This 4‑flute, variable‑index end mill leverages carbide technology and a robust coating to deliver reliable, repeatable results in demanding machining tasks. The 20 mm size designation and square end geometry provide a versatile foundation for complex profiles and tight tolerances.

It offers a wide cutting diameter range from 0.8 mm to 25.0 mm, giving you the flexibility to tackle a variety of pockets, slots, and finishing passes without swapped tooling. A tight diameter tolerance of +0 / -0.03 mm ensures consistent accuracy across passes and multiple parts. The variable index flutes—with a 29° helix on the first flute and 31° on the second—help suppress chatter, extend tool life, and maintain smooth, stable cutting even in tougher materials. The W coating further enhances durability, supporting longer tool life and steadier performance in mold and die work.

• Broad cutting range for versatile tasks: Covers a wide spectrum of pocketing and profiling needs (0.8–25.0 mm) so you can complete varied jobs with a single tool.
• Precise and repeatable cuts: Tight tolerance of +0 / -0.03 mm ensures consistent part dimensions across runs and batches.
• Durable, vibration‑resistant design: Variable index flutes with 29°/31° helix and the W coating reduce chatter and wear, delivering stable finishes and longer tool life.

Across mold and die work, including pre‑hardened steels, this end mill maintains accuracy and reliability from first cut to final pass. It’s engineered to handle machining below 55 HRc, making it a dependable choice for producing precise cavities, cores, and features with fewer tool changes, less rework, and better surface quality. Trust in consistent performance, predictable results, and extended tool life to keep your machining workflow efficient and productive.
