Crafted for engineers, shop floor personnel, and enthusiasts alike, it delivers precise, repeatable performance in a compact, versatile tool system.

Ground profile inserts provide high-precision threading with excellent surface quality, even at demanding machining parameters. The solid, accurate clamping method ensures full repeatability and quick setups. The same insert works for both right-hand and left-hand threads, offering flexible use across multiple projects. Toolholders include a Weldon shank and a coolant bore for secure retention and reliable cooling during longer runs.

  • Precision-ground profile for consistent threading: Delivers accurate thread forms and smooth surface finishes at high machining parameters, improving part quality and reducing rework.
  • Solid, repeatable clamping: Ensures stable performance and reliable repeatability across multiple setups, helping you finish jobs faster with less downtime.
  • One insert for both hand directions: Supports right- and left-hand threads with a single insert, simplifying inventory and increasing workplace versatility.

This threaded milling insert system enhances your workflow by pairing precise cutting with dependable clamping and flexible threading capability. The combination of a Weldon-shank toolholder and integrated coolant bore supports smooth operation, longer tool life, and consistent results across demanding threading tasks.
