Introducing the Carmex Spiral Mill Threading Insert (Metric/ISO) H45I1.5ISOMT7. This spiral-thread insert is designed for threading and end-milling tasks across a wide range of machines, from compact CNC centers to high‑power milling setups. The spiral geometry enables smooth cutting at higher feed rates, helping reduce cycle times and deliver clean, consistent threads. It’s built for engineers, toolmakers, and workshops that need reliable performance on diverse materials.

• Efficient spiral design for fast, smooth cutting: The spiral flute geometry enables high feed rates with reduced machining time, delivering reliable threading and superior surface finish across both small components and heavy-duty applications.
• Flexible, indexable 1–9 insert configuration: Spiral toolholders accommodate 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures optimal indexability and quick, downtime‑saving tool changes.
• MT7 Sub-Micron TiN-coated inserts for broad material compatibility: Inserts feature MT7 Sub‑Micron grade with Titanium Nitride multi‑layer coating (ISO K10‑K20), offering wear resistance and long tool life for threading across a wide range of materials.

Together, these features translate to faster cycle times, consistent thread quality, and dependable performance in both production and prototyping environments. The Carmex spiral insert supports precise, repeatable results—from threading to roughing and finishing—helping you streamline workflows, reduce downtime, and achieve high-quality finishes across materials.
