The Widin Carbide Corner Radius End Mill is a precision cutting tool designed specifically for mold and die work. With a 1 mm cutting diameter, a 40 mm length, and a 0.1 mm corner radius, this 4‑flute end mill is built to handle tight radii and intricate features with dependable accuracy.

Its 4-flute configuration and tapered neck are purposefully chosen to reduce chatter when cutting high‑strength materials, delivering smoother cuts and improved surface finishes. The tapered effective length adds rigidity and stability, making it well suited for deep groove machining and longer reaches without sacrificing precision.

• 4-Flute Design for Efficient, Smooth Cutting: Enables steady material removal with reduced vibration, helping you achieve cleaner finishes and reliable chip evacuation across mold and die work.
• Tapered Neck for Improved Rigidity and Deep Groove Performance: Increases stability and minimizes deflection during deep cuts, maintaining dimensional accuracy and better surface quality.
• 1 mm Ø x 40 mm Length with R0.1 Corner Radius: Supports tight corner radii in molds and dies while reducing stress concentrations, promoting longer tool life and durable, precise fillets.

Designed for consistent, high‑quality results in mold and die applications, this end mill helps you complete precision tasks faster, with fewer passes and less rework. Its combination of small diameter, rigid geometry, and a gentle corner radius delivers reliable performance under demanding production conditions, giving you confidence in every cut.
