Carmex Spiral Mill Threading Insert - Metric/ISO - H17I2.5ISOMT7

The Carmex Spiral Mill Threading Insert (Metric/ISO - H17I2.5ISOMT7) is a high‑performance threading and milling tool system built around a spiral flute design. It enables smooth cutting at high feed rates, dramatically reducing cycle times, and is suitable for a wide range of applications—from small components on compact machining centers to heavy‑duty work on powerful milling machines.

The system uses spiral fluted toolholders that can hold 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures optimal indexability and repeatable results. Inserts are MT7 sub‑micron grade with Titanium Nitride multi‑layer coating (ISO K10‑K20), delivering wear resistance and a high‑quality finish across threading, end milling roughing, and finishing operations.

• Smooth cutting at high feed rates: The spiral flute design enables fast, efficient material removal with reduced machining time and smooth operation across threading and milling tasks.
• Flexible insert capacity with precise indexability: Holds 1 to 9 inserts in a compact cutting diameter, with a unique clamp that ensures reliable index positioning and repeatable results.
• Durable MT7 inserts with TiN coating for universal materials: Sub‑micron MT7 inserts with TiN multi‑layer coating provide long wear life and consistent finishes across a wide range of materials.

Together, these features deliver faster cycle times, fewer tool changes, and reliable, repeatable thread quality and milling finishes. The spiral design reduces vibration and chatter, while the MT7 coating and geometry support durable performance across materials, helping you streamline workflows and improve overall productivity in production environments.
