The Carmex Spiral Mill Threading Insert – Unified – H32E18UNMT7 is a high‑performance spiral milling insert designed to simplify threading and milling tasks across a broad range of machines and materials. From small-part work on compact machining centers to heavy‑duty processing on high‑power mills, this tool is engineered to deliver fast, smooth cuts with precise results.

Its spiral flute design and compact toolholder enable efficient chip evacuation and reduced vibration. The system supports 1 to 9 inserts in a small cutting diameter and uses a unique clamping method to ensure reliable indexability, so you can switch jobs quickly while maintaining consistent finishes in threading, roughing, and finishing passes.

• Smooth, high-feed spiral design: Delivers smooth cutting at high feed rates, reducing cycle times and enabling efficient threading, end milling roughing, and finishing across a wide range of materials.
• Flexible, multi-insert toolholder (1–9 inserts): Holds 1 to 9 inserts in a compact cutting diameter with a unique clamping method for optimal indexability, enabling quick setup and reduced downtime between jobs.
• MT7 Sub-Micron TiN-coated inserts: Inserts are available in MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), a general‑purpose grade that delivers wear resistance across all materials.

Designed for reliability and versatility, this insert helps you speed up production while ensuring repeatable results. The combination of spiral cutting, durable TiN‑coated MT7 inserts, and flexible insert housing supports consistent finishes, fewer tool changes, and improved overall workflow on threading and milling applications.
