The Widin Carbide Corner Radius End Mill for Stainless & Exotics is a precision milling tool built to handle tough metals with confidence. It features a 20 mm diameter and a 1.0 mm corner radius, delivering precise corner radii and dependable geometry for demanding applications.

Its 5-flute, variable-helix design enhances chip emission and helps achieve a smooth workpiece surface on stainless steels and exotic alloys. The cutting edge is formed from high-hardness carbide for excellent wear resistance, and the rake-angle design is tailored to the workpiece characteristics to support reliable machining results.

• Unequal Index Flutes for Efficient Chip Emission: The unequal flute spacing promotes effective chip evacuation and contributes to a smoother surface finish on challenging materials.
• High-Hardness Carbide Edge for Wear Resistance: A robust cutting edge maintains sharpness through demanding cuts, delivering consistent performance and long-lasting tool life.
• Optimized Corner Radius and Rake Angle for Superior Surface Finish: The 1.0 mm corner radius combined with a purpose-built rake angle yields excellent machining surfaces and reliable results on stainless and exotic workpieces.

Designed to work across a range of milling tasks—from precision pocketing to finishing tight radii—this end mill helps you achieve consistent, high-quality results with confidence. The combination of chip-friendly geometry, durable carbide, and carefully tuned rake angle supports a reliable workflow and reduces the need for rework, making it a dependable choice for professionals and serious hobbyists alike.
