Description

The Widin Carbide End Mill is a compact, high-precision tool designed for demanding profiling and slotting tasks. Featuring a ball-nose tip and 3 flutes, it delivers smooth curved contours and consistent finishes on small-diameter workpieces. With a tapered neck, this end mill reduces vibration and chatter for stable cuts during deep grooves and angled surfaces, helping you achieve accurate results in challenging geometries.

Designed for harsh machining environments, it uses a newly developed carbide substrate and coating that support dry cutting and high-speed operation. The tool is built to handle hardened materials up to HRc70, pairing robust performance with reliable durability. Its 2 mm diameter and 20 mm overall length make it ideal for intricate work and tight tolerances.

  • Tapered neck for reduced vibration: The tapered neck minimizes tool chatter during deep grooves and sloped surfaces, delivering stable cuts and longer tool life.
  • Ball-nose geometry for smooth contours: The ball-tip design enables precise, high-quality curved surfaces and fine detailing with consistent finishes on complex profiles.
  • Hard-material capability with advanced coating: Engineered for hard materials up to HRc70, with a coating optimized for dry and high-speed cutting to improve durability and performance in demanding applications.

This end mill helps you complete intricate parts faster with repeatable accuracy. The combination of a precise carbide core, resilient coating, and tapered neck reduces downtime from chatter and wear, accelerates setup and relocation between features, and consistently delivers the reliable, high-quality finishes your projects require.
