Carmex Spiral Mill Threading Insert – Whitworth – H13-19WMT7 is a spiral-fluted threading insert engineered for Whitworth thread forms. It’s designed for a broad range of machining environments, from small components on compact centers to heavy-duty milling on high‑power machines, delivering fast, smooth thread milling with reduced cycle times.

The spiral geometry minimizes cutting effort while maintaining a reliable finish, enabling higher feed rates without sacrificing part quality. The toolholder design accommodates 1 to 9 inserts in a compact cutting diameter, and the innovative clamping method ensures optimal indexability for consistent, repeatable results across multiple passes.

• Smooth cutting at high feed rates: The spiral design delivers efficient material removal with reduced machining time, improving productivity on both small and large parts.
• Efficient indexability with reduced vibration: Spiral toolholders support 1–9 inserts in a compact diameter, with a unique clamping system that maintains precise alignment and minimizes chatter for dependable finishes.
• Durable MT7 Sub-Micron TiN-coated inserts: Sub-Micron Grade inserts with Titanium Nitride multi-layer coating (ISO K10–K20) offer broad material compatibility and extended wear life across diverse materials.

This combination of fast, smooth threading and durable, versatile inserts helps streamline workflows, shorten setup and cycle times, and deliver consistent thread quality across projects. The Carmex Whitworth spiral mill threading insert is built to perform in demanding environments, giving you reliable results and lower long-term tool costs through improved longevity and predictable performance.
