Carmex Spiral Mill Threading Insert - Unified - H15I16UNMT7

The Carmex Spiral Mill Threading Insert - Unified - H15I16UNMT7 is a versatile spiral milling insert designed for threading and precision machining. It’s built for a broad range of machines—from compact machining centers to high-powered milling centers—delivering smooth cutting at higher feed rates and shorter cycle times.

Inserts are available in MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20). This general-purpose grade provides reliable performance across materials and, with a unique clamping method, ensures optimal indexability for consistent results.

• Efficient spiral design for fast, smooth cutting: The spiral geometry enables a smooth cutting action at high feed rates, reducing cycle times and delivering clean thread profiles and finishes in threading, end milling roughing, and finishing tasks.
• Flexible insert capacity with precise indexability: Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, and the unique clamping method ensures optimal indexability for repeatable, accurate results with every pass.
• Durable MT7 Sub-Micron Grade with TiN coating: The inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20) for long tool life and reliable performance across all materials.

This spiral threading insert delivers faster cycle times, steadier cuts, and repeatable results across threading, roughing, and finishing tasks. By reducing vibration and offering a stable indexing system, it minimizes downtime and boosts throughput on both small machining centers and high-power milling machines. With MT7 Sub-Micron Grade inserts and TiN coating, you gain long tool life, consistent surface finish, and broad material compatibility—helping you complete jobs more reliably with less maintenance.
