Description
The Widin Carbide Corner Radius End Mill for Mold & Die is a 20 mm diameter carbide milling tool with a 0.5 mm corner radius (R0.5) designed specifically for mold and die work. Its 3-flute design reduces cutting load on the end face, helping to minimize wear and extend tool life in demanding milling tasks.
Built for high-speed and high-feed machining, the double radius geometry provides enhanced stability and smoother surface finishes on complex corners. The rake angle is thoughtfully optimized to suit a range of workpiece characteristics, delivering consistently excellent surface quality across challenging mold and die applications.
- Reduced cutting load for longer tool life: The 3-flute configuration lowers the cutting load on the end face, reducing wear and extending tool life in tough milling scenarios.
- Enhanced stability and surface finish: The double radius design improves stability at high speeds and feeds, yielding cleaner corners and better surface quality on molded parts.
- Optimized rake angle for consistent quality: Carefully designed rake angle accounts for typical workpiece behavior, helping you achieve reliable, high-quality surfaces with every pass.
This end mill is a reliable choice for professionals and hobbyists alike, supporting efficient workflows, durable performance, and repeatable results across mold and die projects.
