The Carmex Spiral Mill Threading Insert for NPS - H15-14NPSMT7 is a versatile, indexable tool designed for threading and milling tasks. It supports both small-part work on compact machines and heavy-duty milling on larger equipment, delivering fast, smooth cutting and reduced cycle times across threading, end milling, roughing, and finishing.

• Fast, smooth cutting at high feed rates: Spiral flute design enables aggressive material removal with a calm cutting action, helping you complete threads and profiles quickly without sacrificing finish quality.
• Optimized indexability and reduced vibration: A unique clamping method keeps inserts precisely positioned, minimizing chatter and extending tool life in demanding production environments.
• MT7 Sub-Micron TiN-coated inserts for broad material compatibility: The MT7 grade with TiN multilayer coating provides reliable performance across materials (ISO K10–K20), delivering consistent finishes in threading, roughing, and finishing.

The Carmex Spiral Mill Threading Insert helps you streamline production while delivering precise, repeatable results. Its spiral geometry and robust clamping reduce vibration and allow higher cutting forces, which translates to faster cycles and less downtime. The MT7 TiN-coated inserts maintain edge sharpness and wear resistance across materials, helping you achieve consistent thread profiles and high-quality finishes from first part to last. With a single tool and insert family capable of threading, roughing, and finishing, you can simplify setups, shorten changeovers, and boost overall workflow efficiency.
