Description

Widin Carbide End Mill for Graphite – 3 mm diameter x 20 mm length – is a precision cutting tool designed specifically for machining graphite. It’s well-suited for engineers, machinists, hobbyists, and production shops that need reliable cuts on graphite workpieces. The compact 3 mm size and robust carbide construction make it ideal for tight pockets and fine details without sacrificing durability.

Graphite's properties—high thermal conductivity and low friction—call for a tool that stays sharp and cool under load. This end mill delivers with a four-flute design that enhances chip evacuation, helping prevent clogging and enabling smooth, steady cutting from start to finish.

  • Four-Flute Chip Evacuation: The longer flute count improves chip clearance, reduces clogging, and keeps cutting operations smooth for graphite workpieces.
  • Square Edge for Clean, Precise Cuts: The square-cut geometry delivers sharp, accurate passes and leaves high-quality surface finishes on graphite surfaces.
  • Durable Carbide Construction for Long Tool Life: Carbide resists wear and maintains cutting edge sharpness, helping you complete more runs between tool changes.

This end mill helps you streamline graphite milling by delivering dependable, repeatable cuts with minimal downtime. Its combination of efficient chip evacuation, clean edge quality, and durable construction translates to faster cycle times, better surface finishes, and greater confidence in your machining results across prototypes and production runs alike.
