The Carmex Spiral Mill Threading Insert (Unified) H32I12UNMT7 is a versatile spiral-threading tool system designed for threading, end milling, roughing, and finishing tasks. It’s built for a wide range of machines—from compact machining centers to high‑power milling centers—providing smooth cutting at high feed rates to reduce total machining time.

Spiral fluted toolholders accommodate 1 to 9 inserts in a small cutting diameter, while a unique clamping method ensures optimal indexability. The MT7 sub‑micron inserts feature a Titanium Nitride multi‑layer coating (ISO K10–K20) for broad material compatibility and durable, high‑quality finishes.

• Smooth, high‑feed cutting: Spiral design enables a smooth cutting operation at high feed rates, reducing machining time and boosting productivity.
• Flexible, multi‑insert design: Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, enabling efficient setup and tailored performance for threading, roughing, and finishing.
• Durable MT7 TiN‑coated inserts: Sub‑micron MT7 inserts with Titanium Nitride multi‑layer coating (ISO K10–K20) deliver long tool life and reliable finishes across materials.

This system helps you achieve consistent threading and milling results with fewer tool changes, smoother operation, and excellent surface finishes. Its versatility, durable coatings, and easy indexability support faster setups, higher throughput, and reliable performance across a wide range of materials and applications.
