Deskripsi
Mill-Thread Insert – UN 4 TPI, Internal
The 40 I 4 UN MT7 Mill-Thread Insert is specifically designed for internal threading of Unified National (UN) profiles on CNC milling machines using helical interpolation. Designed to cut at 4 TPI, this insert delivers accurate and stable performance for large-pitch Unified threads in heavy-duty mechanical and industrial components. With a size 40 profile, 20 mm height, and 6.3 mm thickness, it provides excellent tool rigidity, clean thread forms, and reliable chip evacuation during deep or large-diameter threading operations.
Manufactured from Carmex’s high-performance MT7 carbide grade, the insert ensures superior wear resistance, dimensional accuracy, and consistent tool life across demanding production cycles. For optimal results, it is compatible with Carmex’s full range of SR series toolholders—available in single, twin, and multi-insert designs, including options with internal coolant and reinforced carbide shanks for added stability and precision.
