Description
Mill-Thread Insert – ISO 5.5 mm Pitch, Internal
The 40 I 5.5 ISO MT7 Mill-Thread Insert is engineered for internal threading of ISO metric profiles on CNC milling machines using helical interpolation. Designed for a coarse 5.5 mm pitch, this insert is ideal for producing strong, wide threads in heavy-duty or large-diameter components. With a size 40 body, 20 mm height, and 6.3 mm thickness, it ensures excellent rigidity, chip evacuation, and thread form accuracy during high-load cutting conditions.
Made from Carmex’s advanced MT7 carbide grade, the insert provides excellent wear resistance, heat tolerance, and extended tool life across production applications. It is fully compatible with the SR series toolholders from Carmex available in single, twin, and multi-insert options, with carbide shank and internal coolant features to enhance tool stability and machining efficiency.
