Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steels and other exotic alloys. With a 6 mm diameter and a 0.5 mm corner radius, it creates clean internal corners and smooth outer surfaces, making it ideal for precision pockets, fillets, and contour work. Its 5-flute, variable-helix geometry helps manage chip flow and reduces vibration for more consistent finishes in demanding materials.
Engineered for engineers, machinists, and hobbyists, this end mill delivers reliable performance across tough materials. The optimized rake angle, tailored to the workpiece characteristics, combines with a sharp carbide edge to produce precise results with minimal cutting forces and surface distortion.
- Unequal index flutes for efficient chip evacuation: The alternating flute spacing improves chip clearance, reduces heat buildup, and supports higher feed rates for a smoother, more consistent surface finish.
- High-hardness carbide with wear resistance: Built to withstand stainless and exotic alloys, the cutting edge resists wear for longer tool life and stable dimensions through repeated use.
- 5-flute, variable-helix design for stability: The combination minimizes chatter and vibration, delivering reliable, top-quality finishes even in demanding contouring and radii work.
With this end mill, you can efficiently produce precise 0.5 mm radius corners and complex profiles, reducing tool changes and rework. The robust carbide construction and thoughtful geometry translate to dependable, repeatable results, improved surface finish, and longer tool life—keeping production running smoothly with fewer interruptions.
