Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for mold and die machining. It features a 20 mm diameter, 100 mm length, and a corner radius of R2, delivering reliable, high-quality finishes across a range of materials for engineers, shop floor operators, moldmakers, and hobbyists alike.
- Four-flute carbide design: Delivers steady cutting performance with efficient chip evacuation, helping you achieve consistent surface finishes in mold and die work.
- Variable index geometry: Reduces vibration and improves chip control for smoother cuts, longer tool life, and better overall machinability.
- Corner radius versatility: Available in multiple corner radius sizes (including R2) to match detailed mold and die features and to deliver precise fillets and finishing.
Designed to streamline your workflow, this end mill maintains tight tolerances and delivers repeatable results across multiple materials and applications. The robust carbide construction, combined with optimized geometry, helps minimize downtime from tool chatter and finish-grade surfaces right off the cut, making it a reliable choice for mold and die projects and other precision milling tasks.
