Description
The Widin Carbide Square End Mill for Mold & Die is a precision cutting tool designed for demanding mold and die work. Featuring a four-flute square end and a long neck, it delivers stable, accurate performance in tight pockets and deep cavities. The tool supports cutting diameters from 1.0 mm to 12.0 mm with a tight tolerance of +0/-0.03 mm, and the listed size example is 1.2 mm diameter with a 20 mm neck length for compact tool geometry.
This end mill is ideal for mold and die machining on materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel. Built from premium carbide and enhanced with a durable W coating, it combines wear resistance with reliable cutting performance to help you finish parts with consistent edge quality and repeatable results.
- Long-neck, high-stability design: The extended neck provides extra rigidity and reduces tool deflection during deep or aggressive cuts, helping prevent breakage and extend tool life in challenging mold pockets.
- Wear-resistant carbide with W coating: Premium carbide paired with a durable W coating delivers outstanding wear resistance, maintaining sharpness longer and reducing tool wear across demanding machining cycles.
- Tight tolerance across a wide range: +/- 0.03 mm tolerance from 1.0 mm to 12.0 mm ensures precise feature definition and repeatable results, making it reliable for mold cavities and detailed die features.
This combination of durability, precision, and versatility helps you achieve smoother finishes, fewer tool changes, and more consistent part quality. It supports efficient workflows in mold and die production, delivering reliable performance on pre-hardened and alloy steels while helping you reduce downtime and extend tool life.
