Description

Widin Carbide End Mill is a compact, precision cutting tool designed for high-accuracy contouring and detailed milling tasks. With a 2-flute, ball-nose geometry and a tapered neck, it delivers smooth cuts and stable performance on curved surfaces and intricate profiles. It’s a versatile choice for engineers, machinists, hobbyists, and fabrication shops tackling molds, prototypes, and complex parts.

Cutting diameter 1.8 mm and neck length 4 mm provide reach into deep pockets and angled surfaces while maintaining rigidity. Crafted from advanced carbide and finished with a durable coating, this end mill supports dry and high-speed cutting and is built to stand up to hard materials up to HRc70, delivering long tool life and consistent performance.

  • Tapered neck for reduced vibration and chatter: Helps stabilize cutting in deep grooves and on sloped surfaces, improving surface finish and extending tool life.
  • Ball nose geometry with 2 flutes: Enables smooth, accurate contouring of complex shapes and efficient chip evacuation for clean finishes on curved features.
  • Hard-wearing carbide with advanced coating: Supports dry and high-speed cutting in tough materials, resisting wear and heat for reliable, repeatable results.

This end mill simplifies demanding work by delivering precise, repeatable results with fewer passes and less downtime. The combination of the tapered neck, robust carbide core, and optimized coating helps you push cutting speeds on difficult profiles while maintaining consistent quality across jobs—from precision molds to intricate prototypes.
