The Carmex Spiral Mill Threading Insert, Unified model H19I12UNMT7, is a flexible spiral milling and threading system designed to cover a broad range of machines and applications. It’s ideal for tasks from threading small components on compact centers to heavy-duty milling on high-power machines, delivering fast, dependable results.

Its spiral design enables smooth cutting at high feed rates, reducing machining time without sacrificing finish. The toolholder accommodates 1 to 9 inserts in a compact cutting diameter, and a unique clamping method ensures optimal indexability—helping minimize downtime and vibration while delivering a high-grade finish in threading, end milling roughing, and finishing.

• High-efficiency spiral design: Enables smooth cutting at high feed rates, cutting cycle times and boosting productivity across a wide range of workpieces.
• Flexible insert capacity with precise indexing: 1–9 inserts in a compact diameter with a unique clamp that ensures reliable indexability and quick tool changes, reducing downtime.
• MT7 sub-micron TiN-coated inserts: MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10–K20) provides broad material compatibility and wear resistance for threading and milling.

This spiral mill threading insert system helps you streamline workflows, shorten setup times, and achieve reliable, repeatable results across threading and milling tasks. The combination of high-feed cutting, reduced vibration, indexed inserts, and TiN-coated MT7 inserts means less downtime, fewer tool changes, and consistent finishes—from threading to roughing and finishing—on a wide range of materials.
