Carmex Spiral Mill Threading Insert is a metric/ISO threading tool designed for precision threading and end milling. Its spiral flute design enables smooth cutting at high feed rates, helping you reduce machining time and increase productivity on both small machining centers and high‑power milling machines.

Spiral fluted toolholders hold 1 to 9 inserts in a compact cutting diameter, and a unique clamping method ensures optimal indexability. The design reduces vibration and chatter while delivering a high‑grade finish across threading, end milling roughing, and finishing operations. Inserts are MT7 Sub‑Micron Grade with Titanium Nitride multi‑layer coating (ISO K10‑K20), a general‑purpose grade suitable for use with all materials.

• High‑Feed Spiral Design: Smooth cutting at high feed rates reduces machining time and boosts overall productivity.
• Flexible Insert Capacity with Optimal Indexing: 1–9 inserts in a compact diameter with a unique clamp method for reliable indexing and reduced vibration.
• MT7 TiN‑Coated Inserts for Broad Material Reach: Sub‑Micron MT7 with TiN coating provides wear resistance and consistently high finishes across threading and milling tasks (ISO K10–K20).

This combination delivers efficient, repeatable results across a wide range of applications. The tool’s fast, smooth cutting, versatile insert capacity, and durable TiN‑coated inserts help speed setups, reduce downtime, and ensure reliable, high‑quality finishes from threading to finishing on both small components and demanding, high‑power milling workloads.
