Carmex Spiral Mill Threading Insert – Unified (H23I24UNMT7) is a versatile spiral-threading system designed for precision threading, end milling roughing, and finishing tasks. Its spiral-fluted design enables smooth cutting at higher feed rates, helping you shorten cycle times and boost productivity across a wide range of machines.

• Spiral design for fast, smooth cutting: Enables higher feed rates with reduced machining time and minimized vibration, delivering cleaner threads and finishes even on challenging materials.
• Flexible, indexable insert system: The spiral toolholder supports 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures reliable indexability and quick, repeatable insert changes.
• Durable MT7 TiN-coated inserts for broad material compatibility: Sub-Micron MT7-grade inserts with Titanium Nitride multi-layer coating (ISO K10–K20) provide wear resistance and consistent threading and milling finishes across a wide range of materials.

Designed to cover everything from small-component work on compact mills to heavy-duty applications on high-power machines, this unified system helps you achieve reliable results, smoother operation, and longer tool life. With quick insert changes, reduced chatter, and proven coating performance, you can streamline workflows, cut downtime, and maintain consistent quality across threading, roughing, and finishing operations.
