Carmex Internal ISO Threadmill Insert 40mm/ 1.5mm

Mill-Thread Insert – ISO 1.5 mm Pitch, Internal

The 40 I 1.5 ISO MT7 Mill-Thread Insert is engineered for internal threading of ISO metric profiles on CNC milling machines using helical interpolation. With a 1.5 mm pitch, this insert is ideal for producing standard fine-pitch internal threads in precision-machined or medium-to-large industrial components. The size 40 body, with a 20 mm height and 6.3 mm thickness, ensures maximum cutting stability, accurate thread profile formation, and efficient chip evacuation under continuous-use conditions.

Manufactured from Carmex’s high-performance MT7 carbide grade, the insert offers outstanding wear resistance, thermal stability, and long tool life.
