The Carmex Spiral Mill Threading Insert (Metric/ISO) H32I1.5ISOMT7 is a high‑performance threading and milling insert designed for a wide range of metalworking tasks. Its spiral geometry allows smooth, stable cuts at higher feed rates, helping you reduce cycle times whether you’re using compact CNC centers or powerful high‑throughput mills.

Designed for versatility, this system accommodates 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures reliable indexability. The result is reduced vibration and chatter and consistently high‑quality finishes across threading, roughing, and finishing operations.

• Spiral geometry for fast, smooth cutting: Enables higher feed rates and shorter machining times while maintaining stable cutting forces for cleaner, more precise threads.
• Flexible insert capacity with reliable indexing: Holds 1–9 inserts in a compact diameter and uses a unique clamping mechanism to ensure repeatable, easy index changes and consistent results.
• MT7 TiN‑coated inserts for durability: Sub‑micron MT7 grade with a Titanium Nitride multi‑layer coating (ISO K10–K20) delivers wear resistance across materials and a reliable finish in threading, roughing, and finishing tasks.

Together, the spiral design, versatile insert capacity, and durable MT7 coating help you complete more parts with fewer interruptions. Expect faster cycle times, smoother operation, and repeatable, high‑quality results—from threading basic external and internal threads to finishing passes on mixed materials. This toolset is built to fit demanding shop environments, providing dependable performance and consistent finishes day after day.
