Description
The Widin Carbide Corner Radius End Mill for Mold & Die is engineered for high-speed, high-feed machining in mold and die work. Its 45° helix promotes efficient chip evacuation and stable cutting at demanding feed rates, helping you move from roughing to finishing quickly.
With a 20 mm diameter, 100 mm length, and 4 flutes, this end mill delivers the rigidity and reach needed for complex cavities. A range of corner radius options, including R2, provides versatility to match different mold geometries and minimize secondary operations.
- High-Feed, 45° Helix: Designed for high-speed material removal with efficient chip evacuation, maintaining cutting efficiency and steady performance in tough materials.
- 4-Flute Rigidity: Four-flute geometry delivers enhanced stability and rigidity during cutting, enabling precise, repeatable results even in demanding mold and die work.
- Versatile Corner Radius Options (including R2): A range of corner radii lets you match cavity profiles accurately, reducing finishing steps and enabling tighter tolerances.
This end mill helps you optimize mold and die workflows by combining fast material removal with reliable, consistent results. The carbide construction and optimized geometry reduce tool deflection and chatter, extend tool life, and minimize downtime, so you can complete projects with greater accuracy and predictability—whether you're roughing large cavities or finishing fine radii.
