The Carmex Spiral Mill Threading Insert (Metric/ISO - H32E2.0ISOMT7) is a spiral milling insert system designed for threading, end milling roughing and finishing. It’s built to cover a wide range of applications—from small components on compact machining centers to heavy-duty work on high-power milling machines. The spiral geometry delivers a smooth cutting action at high feed rates, helping you reduce cycle times while maintaining a high-quality finish.

• Smooth, high-feed spiral milling: The spiral design enables a smooth cutting operation at a high feed rate and reduced machining time, boosting productivity across a wide range of parts and machines.
• Flexible, indexable insert holder: Spiral fluted toolholders hold 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures optimal indexability and minimizes vibration and chatter.
• MT7 TiN-coated inserts for broad material compatibility: Inserts in MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20) provide a general-purpose solution that works with all materials and delivers a high-grade finish in threading, roughing, and finishing.

This combination delivers reliable, repeatable results across threading, roughing and finishing tasks. You gain a smoother workflow, shorter cycle times, and a consistent surface finish across a broad range of materials—empowering you to complete jobs faster without compromising quality.
