Description
Introducing the Widin Carbide Square End Mill for Mold & Die—a high-performance 4-flute variable-index tool built for precision in mold and die work. With a wide cutting diameter range from 0.8 mm to 25.0 mm and a tight tolerance of +0/-0.03 mm, it delivers repeatable, accurate cuts across a variety of tasks. The alternating 29° and 31° helix on the first two flutes reduces chatter and vibration, improving tool life and surface finish. Finished with the durable W coating, this end mill offers enhanced wear resistance and machining stability for demanding mold and die applications below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.
- Broad cutting diameter range: Enables you to tackle fine details and larger contours with a single tool, reducing tool changes and streamlining setups.
- Tight, repeatable tolerance: +0/-0.03 mm ensures precise, consistent dimensions across passes, helping parts stay in spec and reduce rework.
- Variable-index geometry with durable coating: The 29°/31° helix reduces chatter for smoother cuts and longer tool life, while the W coating boosts wear resistance and machining stability on tough steels.
This end mill is designed to improve your workflow, delivering reliable performance, cleaner finishes, and longer tool life across mold and die projects. Whether you’re working with pre-hardened steel, alloy steel, or carbon steel, you’ll experience steadier cuts, fewer interruptions, and consistent results that you can trust for production or precision prototyping.
