Description
Widin Carbide Corner Radius End Mill is a high-precision cutting tool engineered for stainless steel and other exotic alloys. With a 16 mm diameter and a 1.0 mm corner radius (R1.0), it delivers accurate corner geometry while maintaining strong performance in demanding machining scenarios. The 3-flute, double-core design and variable helix reduce vibration and improve chip control for cleaner finishes and reliable results.
This end mill is built for professionals and skilled hobbyists alike, offering consistent results across a range of projects—from precision fixtures to intricate profile work. Its carbide construction provides long wear life under tough cutting conditions, while the unique flute arrangement and double-core geometry promote smooth cutting action and dependable durability.
- Unequal Index Flutes for Efficient Chip Emission: Improves chip control and heat dissipation, helping maintain a clean cut and extend tool life in hard metals.
- Double Core Construction for Anti-Bending Strength: Enhances rigidity and reduces deflection under load, delivering more consistent dimensions and better surface quality.
- Variable Helix with 16 mm x R1.0 Corner Radius for Smooth, Precise Finishes: Minimizes cutting forces and chatter while preserving accurate corner geometry for a professional, smooth finish in stainless and exotic alloys.
This tool supports reliable, repeatable results across jobs, reducing rework and downtime. With its robust construction and thoughtful geometry, it delivers consistent corner radii, smooth finishes, and predictable performance—helping you speed up setups and achieve professional-grade parts with confidence.
