Carmex Spiral Mill Threading Insert – Unified – H15I12UNMT7 is a flexible threading and milling solution built around a spiral flute design. It delivers smooth cutting at high feed rates, reducing machining time on everything from small components on compact machining centers to heavy‑duty milling operations. The spiral toolholder supports 1 to 9 inserts in a compact cutting diameter and uses a unique clamping method that promotes optimal indexability with minimal vibration.

• Efficient spiral cutting: The spiral design enables smooth cutting at high feed rates, helping you complete cycles faster and improve overall productivity on both small parts and demanding milling jobs.
• Compact insert mounting with precise indexing: Spiral fluted toolholders hold 1–9 inserts in a small diameter, with a unique clamp that ensures reliable indexability and easy re‑indexing between passes.
• MT7 TiN-coated inserts for universal use: Sub‑micron MT7 grade with Titanium Nitride multi‑layer coating (ISO K10–K20) delivers durable wear resistance and high‑quality finishes across threading, roughing, and finishing on all materials.

This combination delivers reliable performance across a wide range of applications, helping you maintain consistent thread quality, reduce downtime, and streamline setups. The TiN‑coated MT7 inserts are designed for long life in diverse materials, while the indexable, multi‑insert configuration provides flexibility to adapt to different thread pitches and feature sizes without changing tooling. Choose Carmex spiral mill threading inserts for predictable results, smoother operation, and improved workflow across threading, roughing, and finishing tasks.
