The Carmex Spiral Mill Threading Insert — Unified system (H19I8UNMT7) is a versatile spiral-threading tool designed for a wide range of threading and milling tasks. It’s built for both small components on compact machining centers and heavy-duty work on high-power milling machines, delivering smooth cutting at high feed rates and significantly reduced cycle times.

• Efficient spiral cutting for fast, consistent threads: The spiral flute design enables a smooth cutting action at high feed rates, reducing machining time while delivering reliable threading, roughing, and finishing passes across materials.
• Flexible insert indexing with reduced vibration: Spiral fluted toolholders hold 1 to 9 inserts in a compact cutting diameter, and a unique clamping method ensures optimal indexability while minimizing vibration and chatter.
• Coated MT7 inserts for broad material compatibility: Inserts use MT7 sub-micron grade with Titanium Nitride multi-layer coating (ISO K10–K20), delivering wear resistance and consistent finishes on a wide range of materials.

This tooling supports a streamlined workflow with quick insert indexing, durable wear resistance, and the ability to consistently produce clean threads and high-quality surfaces across varied applications. By combining adaptability, reliable performance, and a finish-ready toolkit, it helps you boost productivity, reduce downtime, and achieve repeatable results from job to job.
