I used it to machine M14 screws into M13 and it worked. The sharpness of the dice was very good.

I was in trouble because I couldn't get this size of this maker I was looking for, but it is a great help for Monotaro.

I bought the spiral tap M22P1.5 in advance, so I bought it to make a set with the tap. It is said that stainless steel cannot be threaded because the material of the die is SKS, but I think that it is sufficient because it is mainly used for threading brass and gunmetal. In terms of price, taps and dies are generally quite expensive at this diameter, so it was very helpful to me when purchasing for DIY purposes. It was cheap but the finish was beautiful.

I was worried about the accuracy because the price is cheap, but I am satisfied because I was able to use it without problems.
