The Carmex Spiral Mill Threading Insert is an ISO metric threading solution designed for a wide range of metalworking tasks. Its spiral design enables smooth cutting at high feed rates, helping you complete threads faster with consistently clean finishes. Built to handle everything from small components on compact machines to heavy-duty milling on high-power centers, this insert is a versatile choice for diverse shop environments.

• Spiral, high-feed cutting for speed and efficiency: The spiral geometry delivers a smooth cutting action at elevated feed rates, reducing machining time and improving surface finish across threading, roughing, and finishing tasks.
• Flexible insert capacity with optimal indexing: Spiral fluted toolholders hold 1 to 9 inserts in a compact cutting diameter, and a unique clamping method ensures reliable, repeatable indexability with minimized vibration and chatter.
• MT7 Sub-Micron TiN-coated inserts for broad material use: Inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), providing wear resistance and dependable performance across a wide range of materials.

This combination of fast, smooth cutting, versatile indexing, and durable, general-purpose inserts translates to reliable threading results and quiet, predictable operation. The system supports precise finishes from threading through roughing and finishing, while the MT7 TiN-coated inserts extend tool life and reduce the need for frequent changes. For shops seeking a single, adaptable solution that performs consistently on multiple materials and applications, this spiral mill threading insert offers a trusted, efficient path to higher productivity.
