The Carmex Spiral Mill Threading Insert (Metric/ISO) is a versatile threading solution designed for metric threads across a wide range of milling centers. It’s ideal for both compact machines handling small components and high-power mills tackling tougher production work, delivering fast, reliable threading with a smooth cut.

Equipped with MT7 Sub-Micron inserts and a TiN multi-layer coating, this spiral-fluted tool delivers a high-grade finish across threading, end milling, roughing, and finishing. The unique clamping method ensures optimal indexability while reducing vibration and chatter for cleaner, more repeatable results.

• Smooth, High-Feed Cutting: Spiral design enables a smooth cutting operation at high feed rates, reducing machining time and boosting throughput.
• Compact, Indexable Inserts: Spiral fluted toolholders hold 1 to 9 inserts in a comparatively small cutting diameter, with a unique clamping method that enables optimal indexability.
• MT7 Sub-Micron TiN Inserts: Inserts are MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), a general-purpose grade that can be used with all materials for reliable threading, roughing, and finishing.

Together, this spiral threading insert delivers faster cycle times, cleaner threads, and consistent results across a broad range of materials and applications. The combination of vibration reduction, easy indexing, and durable coatings keeps downtime low and tool life high, helping you hit production targets with confidence.
