Description

Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steels and other exotic alloys. With a 25 mm diameter and an R1.0 corner radius, this 5-flute end mill delivers strong corners and smooth, clean finishes across demanding materials. The tool’s 5-flute geometry and variable helix help balance cutting forces and reduce vibration, making it a reliable choice for professional shops and serious DIY projects alike.

  • Unequal-index flutes for superior chip control: This flute arrangement promotes efficient chip evacuation and minimizes built-up edge, helping you achieve smoother surface finishes on stainless and exotic materials.
  • 5-flute, variable-helix carbide edge for balanced cutting: The combination of a high-hardness carbide edge with a variable-helix design reduces chatter, supports higher feed rates, and delivers consistent wear life in tough alloys.
  • Corner radius geometry (R1.0) for stronger corners and better finishes: The precise corner radius reinforces edge strength, improves radii accuracy, and reduces stress at the corners for durable, repeatable results.

This end mill is engineered to streamline your workflow by delivering reliable performance, reducing rework, and producing consistent surface quality in stainless and exotic materials. The thoughtful combination of chip control, wear resistance, and precise corner geometry helps you finish jobs faster with confidence, making it a dependable addition to any CNC or manual milling setup.
