Well then i found that the screw for the collar of one bit was stripped the first time i tried to take it off

It measures the bits with mm instead of inch and it doesnt show the cutaway view of the bits so its kind of difficult for me to quickly find the one i need i actually have to go to website and open the photos online then find the one at the same position from my box

I decided to bite bullets and hope the quality of the bits over weights the inconvenience from label

Update 1seller contacted me explained that the label error was due to the shipping error from factory but they dont have solution to fix it except for offering free return
