Description
The Widin Carbide Corner Radius End Mill is a versatile cutting tool designed for mold and die manufacturing, precision machining, and applications requiring accurate corner radii. With a 4 mm diameter and a corner radius of 0.3 mm, it delivers clean, consistent corners and pockets while maintaining efficient material removal.
Equipped with a variable index geometry and a 4-flute design, this end mill optimizes edge distribution for smoother cuts and easier chip evacuation. The long shank provides extended reach for deep grooves and complex cavities, making it suitable for a wide range of molds, dies, and precision parts. It’s available in a wide range of corner radii to match your exact pocket or fillet requirements.
- Variable index geometry: Distributes cutting edges along the flute length to reduce cutting forces and improve chip evacuation, delivering smoother cuts and greater tool life in mold and die work.
- 4-flute design for reliable performance: Balances rigidity and finish quality, enabling steady material removal and consistent surface results in demanding materials.
- Long shank for deep grooves: Provides extended reach to access deep pockets and complex cavities, reducing setup changes and improving process stability.
This end mill helps you achieve precise corner radii and smooth finishes across mold, die, and precision components. The carbide construction offers long tool life and wear resistance, while the combination of variable index geometry and long reach minimizes chatter and downtime, accelerating overall throughput. With reliable rigidity, efficient chip control, and a flexible range of corner radii, it supports consistent results, reduced rework, and higher productivity in both high-speed milling centers and traditional machining setups.
