Description
Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision cutting tool designed for challenging alloys. With a 3 mm diameter and a 0.5 mm corner radius, this 4-flute end mill uses a variable helix to improve cutting stability and surface finish. The unequal index flutes optimize chip flow, helping you achieve clean, consistent results on stainless steels and exotic materials.
- Unequal index flutes for chip control: Improves chip evacuation and reduces heat buildup, helping maintain a smooth surface finish on stainless and exotic alloys.
- Durable 4-flute carbide design: High-hardness cutting edge delivers long tool life and reliable performance when cutting tough materials.
- Variable helix with corner-radius versatility: Reduces vibration and chatter for stable cutting; supports various corner radii to match different pocket geometries and radii requirements, including the 0.5 mm radius on this model.
This end mill helps you finish faster with fewer passes, thanks to efficient chip control and a durable, wear-resistant cutting edge. It delivers repeatable, high-quality results in stainless and exotic workpieces, improving workflow and reducing downtime across a range of precision machining tasks.
