The Carmex Vertical Milling CMT Multi Flute Insert – Threading (S350F4UNMT8) is a vertical milling indexable insert designed to handle a wide range of tasks including threads, grooves and chamfers. It pairs with compatible toolholders to deliver precise, repeatable results at higher machining parameters, making it a reliable choice for engineers, machinists, and hobbyists alike.
- Ground-profile inserts for precision: Ground profiles deliver consistent thread forms and excellent surface quality, even at higher machining parameters.
- Rigid, repeatable clamping: Solid, accurate clamping minimizes runout and ensures repeatable results across multiple passes.
- One insert for right- or left-hand threading: The same insert supports both threading directions; toolholders include weldon shank and coolant bore, and chamfer inserts are available for finishing tasks.
With this Carmex vertical milling solution, you gain a versatile, dependable option that streamlines threading and profiling. The ground-profile inserts provide reliable geometry and smooth finishes, while the robust clamping maintains consistency job after job. The universal RH/LH capability, along with coolant-bore toolholders and available chamfer inserts, reduces setup time and inventory needs, helping you speed production and achieve consistent results across a variety of materials and applications.
