the saying you get what you pay for is true, this was a cheap set and it certainly is,especially the tap and die holders and the markings on the dies on some are unreadable. I don't use imperial sizes as a rule but needed two sizes for a job,and as this set had both in it i opted for this as i probably won't use them again after saying all that they did do the job I wanted them for but wi would not recommend for any regular work
