Widin Carbide Square End Mill For Mold & Die - 4 Flute High Helix (45°) - 4mm x10mm

The Widin Carbide Square End Mill is a precision tool designed for mold and die work. With a 4-flute, 45-degree high-helix geometry, it clears chips efficiently and delivers clean, accurate cuts across a range of tasks. It supports cutting diameters from 1.0 mm to 20.0 mm, giving you flexibility to switch between finishing and roughing without changing tools.

Built for durability, the end mill uses premium carbide and a W coating that enhances wear resistance and stability. It’s optimized for mold and die machining below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel, with a tight diameter tolerance of +0/-0.03 mm to ensure consistent results project after project.

• Wide cutting diameter range (1.0–20.0 mm): Enables multiple tasks with a single tool, reducing tool changes and setup time.
• Precise diameter tolerance (+0/-0.03 mm): Delivers repeatable, accurate cuts for tight-tolerance mold features and finishes.
• 45° high-helix with W coating: Improves chip evacuation, lowers cutting load, and extends tool life in hard steels.

Whether you’re shaping cores, finishing cavities, or pre-machining mold inserts, this end mill helps you complete jobs faster with consistent finishes and fewer rework cycles. The durable carbide core and protective coating resist wear, while the optimized geometry maintains stable performance across the range of materials used in mold and die work. Rely on this tool for reliable results, long life, and predictable performance across demanding applications.
