Carmex Spiral Mill Threading Insert - Metric/ISO - H32I4.0ISOMT7

The Carmex Spiral Mill Threading Insert (Metric/ISO, H32I4.0ISOMT7) is a spiral threading tool designed for precise, efficient thread milling. Its spiral design enables smooth cutting at high feed rates, delivering shorter cycle times across a wide range of work—from small components on compact machines to heavy‑duty milling in high‑power setups.

• Smooth, high‑speed spiral cutting: The spiral geometry enables smooth cutting at high feed rates, reducing machining time and boosting productivity on both small centers and large milling machines.
• Flexible insert count with reliable indexing: Spiral fluted toolholders hold 1 to 9 inserts in a compact diameter, and the unique clamp method ensures optimal indexability with minimal vibration and chatter.
• MT7 TiN-coated inserts for wide material compatibility: Inserts use MT7 Sub‑Micron Grade with a TiN multi‑layer coating (ISO K10‑K20), a general‑purpose grade that delivers consistent threading, roughing and finishing across a broad range of materials.

This combination helps you finish more work in less time: flexible insert configurations, reduced setup and changeover effort, and reliable, repeatable results from threading to finishing. The TiN‑coated MT7 inserts extend tool life under varied materials, while the captive index system minimizes downtime and keeps your workflow moving smoothly.
