The Carmex Spiral Mill Threading Insert is a unified threading insert system designed to deliver smooth cutting and high feed rates across a broad range of milling and threading tasks. It’s suitable for everything from precision small-component work on compact machines to demanding, high-power milling operations. The spiral design minimizes vibrations and chatter, helping you achieve faster cycle times and consistent results.

• Smooth, high-feed cutting: The spiral geometry enables a fast, clean cut with reduced vibration, lowering cycle times and improving surface quality across threading, roughing, and finishing.
• Compact, multi-insert holders: Spiral toolholders accommodate 1 to 9 inserts in a small cutting diameter, offering flexible setups and efficient index changes for continuous production.
• MT7 Sub‑Micron TiN coated, universal grade: Sub-micron TiN multi-layer coating (ISO K10–K20) provides broad material compatibility and long insert life, suitable for a wide range of materials and applications.

This system is built for reliability and versatility. With its durable coating and a unique clamping method that ensures precise indexability, you can depend on consistent performance from threading through end milling roughing and finishing. The result is a streamlined workflow, fewer tool changes, and dependable, high-quality finishes on a wide array of parts.
