These S339J ST300 spiral fluted taps are purpose-built for stainless steel threading, covering metric sizes M3, M4, M5, M6, M10 and M12. Made of premium high-performance tool steel, they deliver stable precision performance for both CNC machining centers and manual operations.
The optimized spiral flute design ensures efficient upward chip evacuation, effectively eliminating chip clogging common in stainless steel tapping. Precision-ground thread profiles guarantee consistent dimensional accuracy, clean burr-free threads and superior workpiece surface finish.
Widely applicable for austenitic stainless steel and high-alloy metals, they feature excellent wear resistance and extended service life. They boost threading productivity, cut tool change frequency and lower overall tooling costs for industrial workshops.
