Description
Widin Carbide Square End Mill for Mold & Die is a precision cutting tool designed for mold and die machining. This 4‑flute end mill features a long-neck design to reach deep pockets and tall features with improved rigidity, and it covers cutting diameters from 1.0 mm to 12.0 mm within a compact 20 mm length. Its square end geometry delivers clean, accurate profiles across a range of applications.
- Long-neck geometry for deeper reach: The extended neck provides clearance for deep cavities and tall features, enhancing stability and reducing the risk of breakage during demanding cuts.
- Broad diameter range with tight tolerance: 1.0 mm to 12.0 mm diameters with a precise +0/-0.03 mm tolerance, enabling consistent part geometry and fewer tool changes across jobs.
- 4‑flute design with W-coated carbide: The 4‑flute geometry ensures efficient material removal and a smooth finish, while the durable W coating and carbide substrate extend tool life for reliable performance in mold and die work.
This end mill is built for reliability in mold and die machining, including applications on steels below 55 HRc, as well as pre-hardened, alloy, and carbon steels. The combination of robust construction, wear-resistant coating, and precise geometry helps improve workflow efficiency, reduces downtime, and supports consistent, high-quality results from prototype milling through production runs.
