The Carmex Spiral Mill Threading Insert — Unified, model H13I12UNMT7 — is a versatile spiral milling insert designed for threading and finishing tasks. Built for everything from compact machining centers to high‑power milling setups, it delivers fast, clean cuts and helps shorten cycle times.

Its spiral geometry, compact insert carrier, and robust clamping provide reliable indexability, reduced vibration, and a high‑quality finish across threading, roughing, and finishing passes. This makes it a solid choice for engineers, machinists, and hobbyists who demand consistent results.

• High‑feed, smooth cutting: The spiral design delivers gentle cutting action at high feed rates, reducing cycle times and minimizing vibration for cleaner threads and surfaces.
• Flexible insert capacity with reliable indexing: Spiral toolholders hold 1 to 9 inserts in a compact diameter; the unique clamping method ensures optimal indexability and repeatable results.
• MT7 TiN‑coated, general‑purpose inserts: Sub‑Micron MT7 grade with Titanium Nitride multi‑layer coating (ISO K10–K20) provides wear resistance and dependable performance across all materials.

This spiral insert system enhances productivity by enabling fast, accurate threading and finishing, while its durable coating and indexing precision help maintain consistency across jobs. Whether you’re enabling small‑lot precision work or heavy‑duty milling, you can rely on steady performance, longer tool life, and a high‑quality finish from start to finish.
