Mill-Thread Insert – ISO 4.0 mm Pitch, Internal
The 40 I 4.0 ISO MT7 Mill-Thread Insert is engineered for internal threading of ISO metric profiles on CNC milling machines using helical interpolation. Designed for a 4.0 mm pitch, this insert is suited for creating coarse internal threads in larger components across industrial and mechanical applications. With a size 40 profile, 20 mm height, and 6.3 mm thickness, the insert ensures high rigidity, accurate thread form, and efficient chip control during demanding cutting operations.
Manufactured from Carmex’s high-performance MT7 carbide grade, this insert delivers excellent durability, wear resistance, and thermal stability, even under high-stress conditions. To maximize performance, it integrates seamlessly with SR series toolholders available in single, twin, and multi-insert formats, including internal coolant channels and carbide shanks for precision and long service life.
