Carmex Vertical Milling CMT Three Flute Insert - Threading (C1811WMT7) is a versatile vertical milling insert designed for threading, grooves, chamfers, and more. It’s ideal for engineers, buyers, tradespeople, hobbyists, and non-technical customers who need reliable, repeatable results from a single insert.

Powered by ground-profile inserts for high precision and performance, this system supports high machining parameters and delivers a high-quality surface finish. The solid, accurate clamping method enables full repeatability, the same insert can be used for right-hand or left-hand threads, and the toolholders include a weldon shank and coolant bore. Chamfer inserts are also available.

• Ground-profile inserts for high precision: Delivers consistent thread forms and smooth surface finishes, even at higher speeds and feed rates, for reliable threading, grooves, and chamfer work.
• Bidirectional threading with one insert: Uses the same insert for both right-hand and left-hand threads, reducing stocking needs and simplifying setup.
• Weldon shank with coolant bore: Provides secure, repeatable clamping in toolholders with integrated coolant delivery, improving chip control and tool life.

This combination of precise geometry, flexible threading capability, and robust tooling helps streamline production, shorten setup times, and deliver consistent results across a range of vertical milling threading applications.
