Description

The Carmex Spiral Mill Threading Insert for BSPT threading (H15-14BSPTMT7) is a versatile spiral-mill tool designed for a wide range of threading and milling tasks. It delivers smooth cutting at higher feed rates, reducing cycle times and boosting productivity on both small machining centers and high-power milling machines. The spiral design helps minimize vibration, delivering consistent, high-quality finishes across threading, roughing, and finishing applications.

  • Smooth cutting at high feed rates: The spiral geometry enables fast material removal with reduced machining time, while suppressing vibration for reliable, consistent results even on demanding jobs.
  • Flexible, indexable insert system: Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, and the unique clamping method ensures optimal indexability for quick setup and efficient tool life.
  • Durable MT7 TiN-coated inserts: Inserts use MT7 Sub-Micron Grade with a Titanium Nitride multi-layer coating (ISO K10-K20), providing broad material compatibility and a high-grade finish across threading, roughing, and finishing operations.

This combination delivers a robust threading solution suitable for everything from precision small-part work to heavy-duty production. The integrated spiral design, reliable indexability, and durable MT7 inserts help you complete more parts per shift with fewer tool changes, while maintaining excellent surface quality across a variety of materials.
