Widin Carbide Corner Radius End Mill for Mold & Die is a versatile 4-flute cutting tool engineered for the demands of mold and die manufacturing. With a 16 mm diameter and a corner radius of R1, this long‑shank end mill excels at deep pocketing, fillets, and rounded features where precision and reach matter. Designed for engineers, machinists, toolmakers, and hobbyists alike, it delivers predictable performance across a variety of materials.

Its variable index geometry optimizes cutting edge distribution, reducing cutting forces and improving chip evacuation for smoother, more efficient machining. The long shank design provides the reach needed for deep grooves and hard-to-access features, making setup more flexible and reducing tool deflection in challenging pockets.

• Variable index geometry for smoother cutting: Optimized edge distribution lowers vibration, reduces load on each edge, and improves chip evacuation for cleaner finishes and longer tool life.
• 4‑flute carbide design for rigidity and efficiency: Increased tool stiffness combined with efficient material removal supports stable cuts and better surface quality in mold and die work.
• Long shank with corner radius R1 for deep pockets: Extended reach and a precise corner radius enable accurate fillets and deep groove machining with minimal deflection.

Whether you’re prototyping, finishing, or producing high‑volume molds, this end mill helps you achieve repeatable tolerances, smooth corners, and reduced downtime. The carbide construction offers wear resistance for long life in tough materials; the long shank enables deeper cavity work without sacrificing rigidity; and the efficient chip removal minimizes heat buildup, helping you maintain consistent results from start to finish.
