It was completely different from what I bought at tap dies set 2000 yen at home center. After turning the item of the home center once after turning it a half turn, it was a type turning further half turn. Just by slowly turning this product, the screw was torn. I am able to go smoothly, it is very pleasant. I definitely recommend it. I bought a long type because the screw was cut only by half in the screw hole of the compo rack case.
There was already a hole in the mount rack, and originally the thread was cut off, it was cut only partway. Purchased for repair. I had to turn slowly the other taps I used before while turning back many times, but this product kept turning slowly as it was, and the screw had run out. Great. I worked very easily.
