Description
Widin Carbide Square End Mill for Mold & Die is a high‑performance milling tool designed for demanding mold and die work. Sized at 4 mm x 10 mm, it features a 4‑flute, variable‑index design to deliver powerful cutting across a range of workpieces. Its cutting diameter range spans 1.0 mm to 20.0 mm with a tight tolerance of +0/−0.03 mm, giving you precise results across different applications.
The tool uses variable index flutes with dual helix angles of 29° and 31°, which help reduce chatter and resonance, extending tool life and providing stable, consistent cuts. A gash tooth shape is incorporated to prevent flute chipping, enhancing durability and reliability. The W coating further boosts wear resistance and longevity, making it well suited for challenging mold and die operations on materials below 55 HRc, including pre‑hardened steel, alloy steel, and carbon steel.
- Wide cutting range with tight tolerance: Delivers precise, repeatable cuts from 1.0 mm to 20.0 mm diameter with +0/−0.03 mm accuracy for versatile mold and die applications.
- Variable index 4‑flute design with dual helix: 29° and 31° helix angles reduce chatter and resonance, improving stability and extending tool life during heavy or continuous cutting.
- Gash tooth and W coating for durability: Gash geometry minimizes flute chipping while the W coating strengthens wear resistance, enabling reliable performance on steels below 55 HRc, including pre‑hardened, alloy, and carbon steels.
This end mill is built for professionals who value consistent performance, reduced downtime, and dependable results in demanding mold and die projects. Its combination of precise sizing, chatter‑mitigating geometry, and wear‑resistant coating helps you finish parts faster with fewer reworks, supporting smoother workflows and improved overall machining outcomes.
