Carmex Spiral Mill Threading Insert - Whitworth - H15-14WMT7

The Carmex Spiral Mill Threading Insert for Whitworth – H15-14WMT7 is a precision spiral milling system designed specifically for Whitworth threading and versatile milling tasks. It suits everything from small components on compact machining centers to demanding, high‑power milling operations, delivering smooth cutting at higher feed rates and shorter cycle times.

Its spiral flute geometry supports 1 to 9 inserts in a compact cutting diameter, while a unique clamping method ensures reliable indexability. The design actively reduces vibration and chatter, helping you achieve clean threads and consistent finishes in threading, end milling, roughing, and finishing. Inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), a general-purpose grade that performs well with all materials.

• Smooth cutting at high feed rates: The spiral design enables a smooth cutting operation at higher feed rates, reducing machining time and boosting throughput on threading and milling tasks.
• Compact, indexable insert capacity: Spiral fluted toolholders hold 1 to 9 inserts in a small cutting diameter, with a unique clamp that ensures optimal indexability and quick, reliable insert changes.
• MT7 Sub-Micron TiN-coated inserts for all materials: MT7 Sub-Micron Grade inserts with Titanium Nitride multi-layer coating (ISO K10-K20) provide wear resistance and broad material compatibility for threading, roughing, and finishing.

Whether you’re an engineer, buyer, or shop-floor professional, this Carmex insert set helps streamline your workflow with reliable performance across a range of applications. The spiral geometry reduces vibration for better surface finish, while the indexable inserts minimize downtime during tool changes. With TiN-coated MT7 inserts designed for durability across materials, you can expect consistent results, easier setup, and improved productivity in both light and heavy milling and threading tasks.
