With a 4 mm diameter, 120 mm overall length and a ball nose radius of 2.0 mm, it delivers accurate contours and smooth finishes across complex shapes. Its 4 mm shank fits typical tool holders, making it a versatile choice for engineers, machinists, and hobbyists alike.

Built with a high-strength cutting edge achieved through an optimized rake angle, this end mill delivers consistent cutting performance and longer tool life under demanding machining conditions. The tool is offered in a wide range of specifications, allowing you to select the exact option that fits your needs—different sizes, flute lengths, and coatings—while maintaining dependable results.

  • 2-Flute Ball Nose for Precise Contouring: Enables accurate contouring, profiling, and slotting with smooth surface finishes and efficient material removal.
  • Optimized Rake Angle for Durable Cutting Edge: Provides strong cutting performance and extended tool life, reducing downtime on tough materials.
  • Wide Range of Specs with 4 mm Shank: Choose from multiple sizes and flute lengths, with coatings available, and a 4 mm shank for secure, versatile integration with standard tool holders.

This combination supports repeatable, high-quality results across mold and die projects, helping you streamline setups, improve throughput, and achieve precise finishes from start to finish.
