Taps were a good price so thought I would give them a try, not even worth the price. Threads on taps pretty much disintegrated as soon as soon as I started to tap into mild steel. Maybe would work for plastic... Also it mentioned in the description 1 taper tap and 1 plug tap of each size/pitch, both of each size were cut exactly the same .

These are really poor quality. They are badly machined and made from low grade steel. I tried one tap on 5mm mild steel plate and the tap completed chewed itself up. I’m contacting vevor for a refund as this is garbage. Avoid these at all costs. Complete waste of time and money.

worst taps ever won't even tap aluminum. some taps do not even have the ends tapered. Tried to get a refund but they offered me 20 bucks, by the time I got to the e mail it was canceled. Also some of the taps are even the wrong diameter the number 10 would not even go in the 10-size hole They made it to the trash can. I have had some good luck with other products but don't buy these
