Widin Carbide Square End Mill For Mold & Die - 4 Flute High Helix (45°) - 12mm x50mm

Widin Carbide Square End Mill for Mold & Die — a precision tool built for demanding mold and die work. This 12 mm diameter, 50 mm overall-length carbide end mill features a 4-flute, 45° high-helix geometry that balances aggressive material removal with smooth, controlled cutting.

Designed for professionals who demand consistency and reliability, it excels on mold steels and pre-hardened alloys, delivering steady performance on steels below 55 HRc and on carbon and alloy grades. The combination of premium carbide and a tough W coating helps resist wear, extend tool life, and maintain stable cutting conditions across tough machining tasks.

• Tight tolerance for precise results: The cutting tolerance of +0/−0.03 mm ensures accurate feature sizes and reduces finishing steps.
• 45° high-helix with 4 flutes for efficient cutting: The 45-degree helix and four flutes reduce cutting load, improve chip evacuation, and support smoother cuts and longer tool life.
• W-coated carbide for durability: Built from premium carbide with a W coating to boost wear resistance and machining stability for mold and die work on steels up to 55 HRc.

This end mill delivers reliable, repeatable performance across a range of mold and die tasks—from forming fine pockets to finishing shallow slots. The robust 12 mm diameter with a 50 mm overall length provides rigidity in standard milling setups, while the optimized geometry and coating help you achieve consistent finishes, reduce downtime, and complete projects with confidence on pre-hardened and alloy steels.
