The Carmex Spiral Mill Threading Insert (Metric/ISO) is a versatile threading and milling solution designed for a wide range of machines—from small machining centers to high‑power milling centers. Its spiral geometry delivers a smooth cutting action, helping you finish jobs faster with consistent results.

The spiral design enables smooth cutting at high feed rates and shorter machining times. Toolholders hold 1 to 9 inserts in a small cutting diameter, and a unique clamping method ensures optimal indexability, reducing vibration and chatter for reliable, repeatable results. Inserts are MT7 Sub‑Micron Grade with Titanium Nitride multi‑layer coating (ISO K10-K20), a general purpose grade suitable for all materials.

• High‑speed, smooth cutting with reduced vibration: Spiral geometry enables a smooth cutting action at high feed rates, lowering cycle times while minimizing vibration and chatter for cleaner threads and better finishes.
• Flexible, compact multi‑insert design: Spiral fluted toolholders hold 1 to 9 inserts in a small cutting diameter, with a unique clamp for optimal indexability and quick setup across diverse job sizes.
• MT7 Sub‑Micron TiN‑coated inserts for universal materials: MT7 Sub‑Micron Grade inserts with a Titanium Nitride multi‑layer coating (ISO K10‑K20) provide wear resistance and consistent finishes on a wide range of materials.

By combining threading and milling capabilities in one spiral tool, this insert system helps you reduce tool changes, shorten setup times, and increase throughput. The design minimizes vibration, supports a broad material range with a durable TiN coating, and delivers reliable, high‑quality finishes on threads, roughing, and finishing operations—giving you a dependable solution for both precise small parts and demanding production runs.
