The Carmex Spiral Mill Threading Insert is a metric/ISO threading solution designed for a wide range of milling and threading tasks. Its spiral flute geometry enables smooth cutting at higher feed rates, helping you reduce cycle times and increase shop productivity. Built to perform from small components on compact machining centers to heavy-duty work on high-powered milling machines, this insert system offers reliable performance across diverse applications.

Inserts use MT7 sub-micron grade with a Titanium Nitride multi-layer coating (ISO K10-K20), delivering durable wear resistance and versatile material compatibility. Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, providing flexible setup and fast index changes. A unique clamping method ensures optimal indexability, while the spiral design helps minimise vibration and chatter for a consistently high-quality finish in threading, end milling roughing, and finishing.

• High-efficiency spiral cutting: Smooth, high-feed cutting that reduces machining time and increases overall productivity on threading and milling tasks.
• Flexible insert configuration: Holds 1–9 inserts in a compact diameter with a clamping system that enables quick, precise index changes for different jobs.
• Durable MT7 TiN-coated inserts: Sub-micron MT7 inserts with TiN multi-layer coating deliver long wear life and reliable finishes across a broad range of materials.

This combination of spiral geometry, versatile insert capacity, and robust MT7 TiN-coated inserts helps you achieve repeatable threading accuracy and clean finishes while reducing downtime and rework. The Carmex Spiral Mill Threading Insert is a dependable choice for engineers, machinists, and shop owners aiming for consistent performance and efficient, high-quality results across diverse production needs.
