The Widin Carbide Square End Mill for Mold & Die is a precision two-flute miniature milling tool designed for demanding mold and die work. Crafted from high-quality carbide and finished with a W coating, it delivers clean pockets and accurate slots with dependable performance across a range of materials. Its focus on precision and durability makes it suitable for both professional shops and ambitious hobbyists tackling detailed mold components. Tight diameter tolerance for repeatable precision: This end mill maintains a precise cutting diameter (+0 / -0.012 mm), helping you achieve consistent dimensions and reduce finishing work and scrap in tight-feature applications. Wide cutting diameter range for versatile use: With a cutting diameter range from 0.3 mm to 25.0 mm, you can handle a variety of small to mid-sized features without swapping tools, improving setup speed and throughput. Durable carbide with W coating and two-flute geometry: The carbide core paired with a protective W coating provides enhanced wear resistance and machining stability, while the two-flute design supports efficient chip evacuation and steady cutting on materials below 55 HRc and related steels. This combination of precision, versatility, and durability helps you complete mold and die projects faster with reliable results. Expect smoother finishes, predictable performance across a range of steels and alloys, and longer tool life that reduces downtime and replacement costs.
