Carmex Vertical Milling CMT Three Flute Insert - Groove Milling - C25W30

The Carmex Vertical Milling CMT Three Flute Insert for Groove Milling (C25W30) is a precision, indexable insert designed for vertical milling applications. Built to tackle threads, grooves, chamfers, and more, it delivers consistent accuracy and clean cuts across a range of materials. The three-flute geometry and ground profile work together to provide stable performance in demanding production environments.

Designed for high parameter machining, this insert offers high surface quality and a solid, accurate clamping method that ensures full repeatability. It can be used for both right-hand and left-hand threads with the same insert, helping simplify tooling inventory. The system pairs with weldon shank toolholders and includes a coolant bore; chamfer inserts are also available to expand capabilities.

• Ground profile for high precision and surface quality: Finely ground geometry delivers tight tolerances and smooth finishes, even at higher speeds and feeds.
• Solid, accurate clamping for full repeatability: A robust locking method minimizes runout, ensuring consistent results across multiple setups and parts.
• One insert, two thread directions: The same insert handles right-hand and left-hand threads, reducing tooling complexity and speeding up changeovers.

This milling insert is crafted to enhance your workflow with reliable performance on groove milling, threading, and chamfering tasks. By combining precision geometry, secure clamping, and versatile thread capability, it helps you achieve repeatable quality, shorter cycle times, and lower tooling overhead—backed by the confidence of trusted Carmex manufacturing.
