Description
Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steel and exotic alloys. Featuring a 1.2 mm diameter and a 0.1 mm corner radius in a 4-flute design, it delivers accurate contouring and superior edge quality in challenging materials.
Its 4-flute variable-helix geometry promotes efficient chip evacuation and stable cutting, while carbide construction ensures long-lasting durability and wear resistance for extended tool life in demanding applications.
- 4-Flute Variable Helix for Stable Cuts: The four cutting edges and variable twist work together to evacuate chips quickly, minimize vibration, and maintain consistent material removal across tough materials.
- Corner Radius for Precise Contouring: The 0.1 mm corner radius enables accurate, smooth corners and reduces the risk of chipping or fracture, delivering cleaner, higher-quality finishes.
- Carbide Construction for Durability: Hardened carbide resists wear and heat in stainless and exotic alloys, providing long tool life and dependable performance across jobs.
This end mill helps you improve workflow by reducing tool changes and rework, delivering repeatable, high-quality finishes, and enabling precise geometry in challenging materials. Its durability and excellent chip control make it a reliable choice for professional shops, engineers, buyers, tradespeople, and hobbyists alike.
