Description

The Widin Carbide End Mill is a 2-flute, long-neck ball-nose milling cutter designed for precision contouring, pockets, and fillets. Built for engineers, machinists, and hobbyists, it delivers accurate geometry and reliable performance in a compact, easy-to-use form.

Its center-cutting design and 30° helix support efficient cutting, clean edges, and smooth surface finishes on deep grooves and sloped surfaces. The tapered neck reduces vibration and chatter, and the adjustable neck length lets you tailor the rake angle for a wide range of parts and setups.

  • Long-neck ball-nose geometry for deep pockets and smooth contours: The extended neck reaches tight corners and deep grooves, while the rounded tip delivers smooth fillets on complex surfaces for consistent part geometry.
  • Center-cutting with 30° helix for clean, precise cuts: Enables plunging and efficient chip evacuation, reducing burn marks and improving edge quality on hard materials.
  • Tolerance and high-hardness carbide for HRc70 materials: With a +0/−0.005 mm tolerance, this cutter maintains tight dimensional control, while a high-hardness carbide core and advanced coating withstand wear during dry, high-speed cutting for longer tool life.

This end mill helps you tackle complex geometries with confidence. The combination of deep-reach neck, smooth ball-nose geometry, and a robust, wear-resistant carbide core translates to faster cycles, fewer tool changes, and consistently accurate pockets, fillets, and ramps. Its dry-cutting capability and high-speed performance reduce setup time and downtime, while the tapered neck and adjustable neck length provide flexibility across a wide range of parts and materials.
