Yamawa Spiral tap for hard-to-cut stainless steel

This spiral tap is ideal for drilling blind holes in hard-to-cut stainless steels such as SUS316 and SUS317.
The SU2-SP uses a special shape that leaves a few full threads on the screw section and removes half of the remaining threads.
The special shape of the screw part effectively prevents chipping of the entire thread, reduces tapping torque and frictional resistance, and maintains screw guideability.
The unique groove shape improves chip removal.
For blind hole machining.
Workpiece materials: low carbon steel, medium carbon steel, high carbon steel, alloy steel, stainless steel.
