Description

The Widin Carbide End Mill—Ball Nose, 4 Flute, Regular Length, 4 mm diameter—is a high-performance cutting tool designed for precision milling across a variety of materials. Its ball nose profile lets you create smooth, rounded contours and precise shapes, ideal for fillets, slots, and complex curves.

Built from carbide for exceptional durability and wear resistance, this end mill maintains sharpness and consistent performance over many jobs. The 4-flute design provides improved chip evacuation and reduces cutting forces, enabling higher cutting speeds and increased productivity. The regular-length design offers versatility and easy handling for a wide range of milling tasks.

  • Ball Nose Geometry for Smooth Contours: Creates consistent fillets and gentle transitions, delivering smooth surface finishes on curved features across materials.
  • Four-Flute Design for Efficient Chip Evacuation and Higher Speeds: The extra flute improves chip clearance, reduces cutting forces, and enables faster feeds and improved productivity.
  • Carbide Construction with Regular Length for Durability and Versatility: Carbide provides exceptional wear resistance and long tool life, while the regular-length body supports a wide range of depths and applications.

Designed to deliver reliable results, this end mill helps you complete parts faster with fewer interruptions. The combination of ball nose geometry and four-flute design supports precise contours and clean finishes, while carbide durability reduces tool changes and downtime. Its versatility makes it a dependable choice for both prototyping and daily production tasks in standard CNC setups.
