Description
The Widin Carbide Square End Mill for Mold & Die is a precision cutting tool designed for mold and die work, including pre-hardened steels. It covers a cutting diameter range from 1.0 mm to 12.0 mm with a tight tolerance of +0/-0.03 mm, helping you achieve consistent, accurate pockets, slots, and features with fewer passes.
Crafted from the finest raw materials and finished with a durable W coating, this end mill is built for longevity and stable performance across demanding jobs. A long transition between the shank and neck provides extra strength where the tool is most prone to stress, reducing breakage during heavy cuts.
- Long-neck transition design: Extends tool life by improving rigidity and clearance at the neck, helping prevent breakage during deep pockets and aggressive milling.
- Durable W-coated carbide: The W coating enhances wear resistance, delivering longer tool life and more stable performance in challenging materials.
- Wide diameter range with tight tolerance: 1.0–12.0 mm cutting diameters with a +0/-0.03 mm tolerance enable precise, repeatable results across multiple features and parts.
This end mill helps you streamline mold and die production by delivering accurate geometry with fewer tool changes and less rework. Its robust construction and wear-resistant coating stand up to repeated cycles in alloy, carbon, and pre-hardened steels, improving overall throughput and reducing downtime.
