The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool designed for mold builders, die makers, engineers, and machinists. Its 4-flute geometry and tapered neck reduce cutting forces and chatter, producing smoother cuts and better surface finishes.

With a corner radius of R0.3 to maintain fillet integrity in complex cavities, the tapered neck increases rigidity for deep-groove work. It is offered in multiple specifications to let you choose the optimal effective length for your machining project.

• 4-Flute design for smooth, consistent cutting: The four-flute geometry balances material removal with finish quality, reducing chatter and delivering cleaner surfaces on mold and die workpieces.
• Tapered neck for added rigidity: The tapered effective length increases stiffness and stability during deep-groove machining, minimizing deflection and helping you hold tighter tolerances with less tool wear.
• Corner radius geometry for precise mold/die edges: The R0.3 corner radius preserves fillet geometry in complex cavities, reducing edge chipping and delivering repeatable radii in molded parts.

Designed for mold and die applications, this end mill helps you achieve precise corners, smoother surfaces, and longer tool life across a range of materials. The combination of four flutes, a tapered neck, and a compact corner radius reduces vibration, supports efficient cutting, and enables consistent results, time after time.
