The Carmex Spiral Mill Threading Insert (Metric/ISO) is a high-efficiency threading tool designed to deliver clean threads and smooth milling finishes. Suitable for a broad range of machines—from small precision centers to heavy‑duty mills—it supports fast, stable cutting and reduces overall machining time.

• Smooth, high-feed threading: The spiral flute geometry enables a smooth cut at high feed rates, reducing cycle times and boosting productivity on both small components and demanding applications.
• Compact, versatile insert array: Spiral toolholders hold 1 to 9 inserts in a small cutting diameter, with a unique clamping method that ensures optimal indexability and repeatable results.
• Coated MT7 inserts for broad material reach: Inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10–K20), delivering wear resistance and lower friction for reliable threading, roughing, and finishing across many materials.

By choosing this spiral milling system, you gain faster production cycles, reduced downtime from quick indexing and setup, and consistent, high-quality results across threading and finishing operations. The MT7 coated inserts provide durable performance across a wide material range, helping you improve workflow, cut cycle times, and minimize rework with every job.
