Description
The Widin Carbide End Mill is a 4-flute neck-type square-edge cutter designed for demanding milling tasks. With a 4 mm diameter, it excels in pockets, slots, and profiles on hard materials, making it a reliable choice for engineers, machinists, and hobbyists alike. Built to handle high-hardened workpieces, this tool delivers dependable performance in challenging environments.
- Hard material capability (up to HRc70): Engineered to machine very hard steels and alloys, reducing the need for tool changes and enabling you to complete tough jobs with consistent results.
- Neck-type 4-flute square-edge design: Provides improved rigidity and a smooth cut, while efficient chip evacuation minimizes clogging and delivers a cleaner finish—especially helpful on deep pockets and challenging contours.
