Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die work as well as general deep-groove milling. Featuring a 4-flute configuration and a tapered neck, it delivers smoother cuts and refined surface finishes by reducing chatter and improving stability. Suitable for engineers, machinists, toolmakers, and hobbyists, this end mill provides reliable performance and extended tool life in demanding molding applications. Specifications include a 4 mm diameter, 40 mm length, and a 0.2 mm corner radius.

• Chatter reduction and smoother finishes: The 4-flute carbide design with a tapered neck minimizes vibration and tool deflection, producing cleaner cuts and superior surface quality even in tough materials.
• Enhanced rigidity for deep grooves: The tapered effective length increases stiffness, delivering precise, stable cuts in deep grooves and intricate mold/die features.
• Flexible length options for your setup: Available in multiple specifications, allowing you to choose the optimum effective length for your project and maximize tool life and performance.

This end mill helps you achieve consistent, high-quality results with fewer passes and less rework. Its robust carbide construction and thoughtful geometry support accurate corner radii and smooth finishes in mold and die components, improving workflow, reducing downtime, and delivering reliable performance across a range of demanding manufacturing tasks.
