Description
Widin Carbide Square End Mill for Mold & Die is a high-performance milling tool designed to tackle demanding mold and die applications. It covers a cutting diameter range from 1.0 mm to 20.0 mm and maintains a tight tolerance of +0/-0.03 mm, delivering precise, repeatable results across a wide range of workpieces. This end mill is built for engineers, machinists, and shops that demand reliable, consistent cutting performance in challenging steels and tooling tasks.
Engineered for reliability, the tool uses a variable-index 4-flute design with helix angles of 29° and 31° to reduce chatter and vibration, extending tool life and delivering smoother finishes. Its gash tooth shape helps prevent flute chipping under heavy loads, increasing durability in mold and die work. The W coating further enhances longevity, helping the end mill resist wear and maintain sharpness longer, while its capability to machine materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel, makes it a versatile choice for a wide range of molds and dies.
- Variable-index 4-flute design for stable cutting: The 4-flute geometry with 29° and 31° helix angles minimizes chatter, improves cutting stability, and extends tool life for smooth, predictable performance.
- Gash tooth geometry to prevent flute chipping: Durable edge geometry reduces flute chipping under heavy loads, delivering reliable durability in demanding mold and die operations.
- W-coated carbide for wear resistance: Premium carbide with a W coating offers enhanced wear resistance and longevity, capable of machining materials below 55 HRc, including pre-hardened, alloy, and carbon steels.
This end mill combines precise tolerancing, vibration control, and long-lasting wear resistance to help you complete mold and die projects faster, with fewer tool changes and less rework. It supports consistent feature definition, better surface finishes, and dependable performance across a broad range of steels, making it a trusted choice for professional shops and serious hobbyists alike.
