Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steel and exotic materials. With an 8 mm cutting diameter and a 0.2 mm corner radius, it delivers controlled radii and clean, accurate corners for demanding machining tasks.
Built as a carbide end mill with four flutes and a variable helix, it is designed for stable cutting, efficient chip evacuation, and smooth finishing across hard materials and exotic alloys.
- Unequal index flutes for improved chip emission and surface finish: The uneven flute spacing promotes efficient chip evacuation and helps produce a smoother finish on the workpiece, even in challenging materials.
- 4-flute design with variable helix for stability: The combination of four flutes and a variable helix provides steadier cuts and reduces vibration, resulting in consistent, high-quality surfaces.
- High-hardness carbide edge for wear resistance: A hard cutting edge delivers excellent wear resistance, extending tool life when machining stainless and exotic alloys and maintaining reliable performance over time.
This tool helps you finish corners cleanly, reduce downtime from tool changes, and deliver repeatable, professional results across a range of stainless and exotic materials.
