Meet the Carmex Spiral Mill Threading Insert – a metric/ISO threading tool designed for spiral milling that delivers smooth cutting at high feed rates and reduced machining time. Built for a broad range of machines—from compact machining centers to high-power milling centers—it supports threading, roughing, and finishing with a consistently high-quality finish.

• Efficient spiral threading and milling: The spiral design enables fast material removal with smooth cutting at high feed rates, helping you reduce cycle times and boost productivity on everyday jobs and complex components alike.
• Flexible, indexable insert configuration: Spiral fluted toolholders accommodate 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures optimal indexability for reliable, repeatable results.
• MT7 TiN-coated inserts for all materials: Inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), delivering durable performance and general-purpose versatility across a wide range of materials.

This combination of smooth operation, adaptable insert configuration, and robust coating translates into steadier milling performance, reduced downtime, and consistent thread and finish quality across projects. Whether you’re threading small components or tackling heavy-duty milling tasks, you’ll experience reliable results backed by proven tooling design and material standards.
