The Widin Carbide Corner Radius End Mill is a high-feed-rate cutting tool designed for mold and die work. With a 12 mm diameter, 110 mm overall length, and an R1 corner radius, it delivers aggressive material removal with precise, stable performance in tough materials. Its 4-flute design and 45° helix angle optimize chip evacuation and enable reliable high-speed machining, making it a versatile choice for engineers, machinists, and hobbyists tackling demanding mold projects.

• 45° helix for efficient chip evacuation: The 45-degree angle guides chips away from the cutting edge and promotes faster material removal while controlling heat, helping maintain tool life in high-speed operations.
• 4-flute design for stability: Four flutes provide rigidity and balance, reducing deflection for smoother cuts and more consistent finishes on tough materials.
• Corner radius options for mold and die: Versatile corner radii (including R1) let you match feature geometry precisely, enabling stronger fillets and better part quality without extra tool changes.

This end mill helps you optimize workflow by combining high-speed capability, durability, and precise corner radii into one tool. With this, you can shorten cycle times, minimize tool changes, and achieve repeatable, high-quality finishes on molds and dies—even in demanding materials—giving you greater confidence in every run.
