THREADING TOOLS

Commonly, for the thread taps, high-speed steel (HSS-PM) achieves excellent performance, and the fine-grain structure provides better strength and tool resistance during production to achieve a longer lifespan and durability. 

For thread mills and indexable thread inserts, we always use the ultra-fine grain cemented carbide matrix to ensure sharpness and toughness. Our carbide thread mills can machine hardened materials up to HRC 65 while maintaining the thread shape and tool lifespan.

Tapping and thread milling are both common in CNC machining, but they are different in application scenarios. Tapping tools are suitable for high-speed tapping and small-batch production, but they are lacking in flexibility. However, thread milling cutters can better control large-diameter or deep threads. Moreover, thread milling is also suitable for precision threading where thread sizes require adjustments.

Best threading tools for stainless steel should feature exceptional resistance to tool wear and built-up edge.  To achieve improved flexibility and durability, we recommend you use solid carbide thread mills for CNC thread milling of heat-resistant alloys. Indexable thread turning inserts are well-suited for creating external threads. You can choose solid carbide thread mills with optimized rake angle and chip evacuation to extend tool life.

In CNC tapping operations, you should choose the correct thread tapping tools with suitable cutting parameters to avoid tap breakage.

Remember to adopt the  proper tapping drill size to provide enough chip space. For blind holes, you can select spiral flute taps, while choosing spiral point taps for machining through holes. Using the proper cutting speeds and feed rates is crucial for preventing excessive torque, and  efficient internal coolants or cutting fluid can also decrease heat generation.
