Carmex Vertical Milling CMT Three Flute Insert - Threading (C18I3TRMT7) is a vertical milling indexable insert designed to handle threading, grooves, chamfers, and more when paired with compatible toolholders. It enables efficient, flexible operations across a wide range of machining tasks.

Ideal for engineers, shop-floor buyers, tradespeople, hobbyists, and non-technical users, it combines ground-profile precision with the ability to run at high machining parameters while maintaining high surface quality. The solid clamping method ensures full repeatability, and the same insert works for either right- or left-hand threads. Toolholders include a weldon shank and coolant bore, and chamfer inserts are available.

• Ground profile inserts for high precision: Delivers tight tolerances and clean thread profiles with consistent results, even at higher machining parameters, helping you achieve better thread quality and surface finish.
• Solid and accurate clamping for full repeatability: Ensures repeatable results across parts, reduces setup time, and minimizes downtime between jobs.
• RH/LH compatibility with coolant-ready toolholders: One insert handles both right- and left-hand threads; toolholders include weldon shank and coolant bore, with chamfer inserts available to expand your capabilities.

Designed to simplify threading operations and expand your machining options, this insert boosts workflow efficiency, delivers reliable performance across jobs, and helps you achieve consistent results from prototype through production.
