JIS B-4430 & Form C 35° SP Explained:
The JIS B-4430 standard is a Japanese Industrial Standard that defines the specifications and tolerances for threading tools like this tap. Form C describes the chamfer style, which is typically used for blind holes because the chamfer is only 2-3 threads long. The designation 35° SP stands for "Spiral Point" with a rake angle of 35°, which allows for efficient chip evacuation forward, making it easier to cut threads in blind holes.
