Meet the Carmex Vertical Milling CMT Multi Flute Insert – Grooving – SG350FW40TMT8. This vertical milling insert system is designed for machinists, engineers, and fabricators who need precise grooves, accurate threads, and clean chamfers using a single, adaptable platform.
Ground-profile inserts deliver consistent geometry for high-precision results, even under demanding cutting conditions. The solid clamping method minimizes runout and ensures full repeatability, while a single insert can handle both right- and left-hand threads, reducing setup time and inventory. The accompanying toolholders feature a Weldon shank and a coolant bore, and chamfer inserts are available for fast, reliable bevel work.
- Ground-profile inserts: Tight tolerances and carefully shaped profiles maintain precise geometry for threads, grooves, and chamfers, delivering high surface quality at higher cutting speeds.
- One insert for both thread directions: Simplifies stocking and reduces tool changes by allowing the same insert to cut right- or left-hand threads with consistent performance.
- Rigid, coolant-ready toolholders: Weldon-shank holders with coolant bore provide stable clamping, efficient chip evacuation, and reliable coolant delivery for longer tool life and cleaner finishes.
This vertical milling system empowers you to streamline workflows, cut more parts per shift, and achieve repeatable, high-quality results across threading, grooving, and chamfering tasks. By combining precision inserts, versatile threading capability, and robust toolholders, you can reduce downtime, simplify tooling inventory, and maintain tight tolerances with confidence.
