The Widin Carbide Corner Radius End Mill is a high-precision cutting tool designed for machinists who need reliable corner radii in hard-to-machine materials. With an 8 mm diameter, a 0.3 mm corner radius, and a long shank, it delivers deep-access performance for challenging grooves and pockets.

  • Diameter: 8 mm
  • Corner Radius: R0.3 for precise, clean radii in corners
  • Flutes: 4-flute design for efficient chip evacuation and rigidity
  • Material: Carbide for hardness, wear resistance, and long tool life
  • Shank: Long shank for enhanced reach in deep grooves and pockets
  • Cutting Edge Geometry: Optimized corner-radius edge for stability and consistent finishes on high-hardness workpieces

This end mill excels where precision and reliability matter most—machining tough materials with tight radii and deep geometric features. The aggressive yet controlled edge geometry minimizes deflection, reduces chatter, and helps you achieve smooth, repeatable finishes. The long reach expands your tool-access footprint, enabling accurate operations in recessed or hard-to-reach areas without compromising stability or surface quality.
