The Carmex Spiral Mill Threading Insert, Unified series H23E20UNMT7, is a versatile threading and milling tool designed for both precision small-part work and demanding high-power milling. Its spiral design enables smooth cutting with a high feed rate, helping you reduce cycle times without compromising finish quality.

Optimized for threading, end milling, roughing, and finishing, this insert solution is ideal for machine shops, job shops, and maintenance teams that demand reliable performance across a wide range of materials.

• Efficient, high‑feed spiral cutting: The spiral geometry delivers smooth, consistent material removal at high feed rates, cutting machining time and enabling faster production without sacrificing surface finish.
• Flexible insert capacity with reliable indexing: Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, and the unique clamping method ensures optimal indexability for quick, repeatable tool changes.
• Durable, broadly compatible MT7 inserts: Inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10–K20), delivering wear resistance and reliable performance across a wide range of materials for threading and milling tasks.

This tool supports smoother workflows, fewer setup interruptions, and consistent results across threading, roughing, and finishing operations. With its robust design and universal insert grade, it helps you maintain productivity, extend tool life, and achieve reliable, high-quality finishes in diverse applications.
