The ones our customers buy most.Description
The Carmex Vertical Milling CMT Three Flute Insert for Threading is a precision vertical milling insert and compatible toolholder system designed to tackle threading, grooves, and chamfers with reliable, repeatable results. It’s built for a wide range of applications—from professional shops to DIY workbenches—delivering consistent performance across materials and production demands.
Featuring ground-profile inserts for high precision and excellent surface quality, the system is engineered to perform at higher machining parameters while maintaining tight tolerances. The solid, accurate clamping enables full repeatability, and the same insert can be used for both right-handed and left-handed threads. Toolholders include a Weldon shank and a coolant bore, and chamfer inserts are also available to expand finishing options.
- Ground-profile inserts for high precision and surface quality: Delivers accurate thread forms and smooth finishes even at higher speeds, helping you meet tight tolerances consistently.
- Solid, repeatable clamping: Ensures stable setups and repeatable results, reducing rework and downtime across multiple production runs.
- Versatile threading with dual-hand capability and coolant-ready toolholders: One insert works for both right- and left-hand threads, while Weldon-shank toolholders with coolant bore support efficient cooling and reliable performance; chamfer inserts are also available for extended finishing options.
These features work together to streamline your workflow, improve throughput, and deliver dependable threading and finishing results. By using a single, repeatable solution for threading, grooves, and chamfers, you can shorten setup times, maintain consistent quality, and keep projects on schedule with confidence.
