Description
The Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision cutting tool designed for challenging materials, featuring a 9 mm diameter and a corner radius of 0.2 mm. It uses four flutes and a variable helix to balance aggressive material removal with consistent corners and smooth finishes.
- Unequal index flutes for improved chip emission: Efficient chip flow and a smoother surface finish when machining stainless and exotic materials.
- High-hardness carbide edge for wear resistance: Durable cutting edge resists wear, extending tool life and maintaining sharpness in tough alloys.
- Four flutes with variable helix for stable cutting: Reduces vibration and chatter, delivering more consistent hole sizes and surface quality.
This combination helps you complete tasks with fewer tool changes, less downtime, and reliable results across demanding materials. The tool’s precise geometry and robust construction support tight tolerances and high-quality finishes, making it a dependable choice for professionals and serious hobbyists alike.
