Meet the Widin Carbide Corner Radius End Mill for Graphite (WGR502) — a precision cutting tool designed for machinists and engineers working with graphite. Its 2-flute neck-type design and small corner radius deliver stable, clean cuts with durable carbide performance.

  • Diameter x Overall Length: 4 mm diameter with 20 mm overall length for versatile reach in graphite components.
  • Flute Count: 2 flutes optimized for efficient chip control and smooth, consistent cutting in graphite.
  • Neck Type: Neck-type geometry increases stability and rigidity during milling in tight pockets and challenging geometries.
  • Corner Radius: Corner radius of R0.2 minimizes edge chipping and yields precise radii on graphite parts.
  • Material: Solid carbide construction delivers excellent wear resistance and extended tool life in graphite applications.
  • Application Focus: Specifically engineered for graphite materials, including electrodes and carbon-based components, where heat and friction are considerations.
  • Chip Evacuation: Geometry supports efficient chip removal to maintain cut quality and reduce re-cutting risks.

This end mill is ideal for operators seeking dependable, long-lasting performance when shaping graphite. The combination of a sturdy neck design, two sharp flutes, and a precise 0.2 mm corner radius helps produce accurate profiles, smooth finishes, and repeatable results across repetitive tasks and tight tolerances. Use in graphite machining where clean radii and controlled cutting forces matter, and expect consistent tool life with reduced risk of breakage.
