Carmex Spiral Mill Threading Insert - Unified - H17I14UNMT7

The Carmex Spiral Mill Threading Insert — Unified — H17I14UNMT7 is a versatile spiral cutting system designed for threading and milling in a single, reliable tool. It targets a broad audience—from engineers and machinists to hobbyists—delivering fast, accurate results in both small-part work on compact machines and demanding production on high-power mills. The spiral design promotes smooth cutting at high feed rates, helping reduce overall machining time.

Spiral fluted toolholders hold 1 to 9 inserts in a compact cutting diameter, enabling quick changes and flexibility across a wide range of threading and milling tasks. A unique clamping method ensures optimal indexability, while the design minimizes vibration and chatter to deliver a consistently high-grade finish on threading, roughing, and finishing operations. Inserts are MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10–K20), providing durable performance across different materials.

• Fast, smooth spiral cutting: Enables smooth cutting at high feed rates to shorten cycle times and improve productivity across diverse threading and milling applications.
• Compact, versatile insert housing: Holds 1 to 9 inserts in a small cutting diameter with a unique clamp for reliable indexing and easy setup, suitable for both small centers and heavy-duty machines.
• Durable MT7 TiN-coated inserts: Sub-Micron grade inserts with a TiN multilayer coating deliver long tool life and reliable performance on all materials, from soft metals to tougher alloys.

This unified system helps streamline your workflow by combining threading and milling capabilities in one tool, reducing tool changes and setup time. The combination of spiral geometry, stable indexing, and a robust coating translates to consistent thread quality, fewer reworks, and increased confidence in every operation—whether you’re prototyping a part or running high-volume production.
