The Carmex Spiral Mill Threading Insert – Unified – H32E16UNMT7 is a spiral-fluted threading insert designed for smooth cutting and fast material removal. It’s suitable for a broad audience—from engineers and shop-floor technicians to hobbyists—delivering reliable threading, end milling, roughing, and finishing in a single compact tool. Whether you’re working on small components on a compact machining center or tackling heavy-duty milling on a high-power machine, this insert is built to reduce cycle times and improve surface quality.

• Smooth cutting at high feed rates: Spiral geometry enables a smooth cutting operation at high feed rates, helping you achieve faster machining and shorter cycle times without sacrificing finish.
• Flexible, indexable multi-insert design: Spiral fluted toolholders hold 1 to 9 inserts in a compact cutting diameter with a unique clamping method that enables optimal indexability and reduces vibration.
• Durable MT7 Sub-Micron TiN-coated inserts: Inserts are MT7 Sub-Micron Grade with Titanium Nitride multilayer coating (ISO K10–K20), delivering wear resistance and consistent performance across a range of materials.

This combination delivers reliable results across threading, roughing, and finishing applications, helping you maintain productive workflows, reduce downtime, and achieve high-quality, repeatable finishes on a wide variety of parts.
