Description

Carmex Spiral Mill Threading Insert – Metric/ISO, model H23I1.5ISOMT7, is a precision spiral milling tool designed for threading and end milling tasks. It’s built for a wide range of users—from engineers and buyers to tradespeople and hobbyists—delivering fast, reliable cutting with a clean, high-quality finish on a variety of materials.

  • Smooth, high‑feed cutting: Delivers efficient threading and milling at high feed rates, reducing cycle times and machining time while minimizing vibration and chatter for stable, consistent results.
  • Flexible insert carrier and precise indexing: Spiral fluted toolholders hold 1 to 9 inserts in a compact diameter with a unique clamping method, enabling reliable indexability and quicker, repeatable setups.
  • Durable MT7 TiN-coated inserts: Inserts use MT7 Sub‑Micron Grade with Titanium Nitride multilayer coating (ISO K10–K20), delivering long tool life and consistently high-quality finishes across all materials.

This insert equips shops to tackle both light-day precision threading and tougher milling workloads with confidence. The combination of spiral geometry, versatile insert capacity, and a hard-wearing coating translates to reduced downtime, steadier operations, and dependable performance from small machines to high‑power milling centers.
