yes the machining is one thing..source materials are another. I dont know wher DV gets their 5mm tubing, but just about all the stuff on ebay and amazon are Chinese Sources. There can be tolerance variation, but that true now days with most all sources.
I was really surprised when I actually measured my fractional drill bit sets...It never occured to me that the drill bits would not be the actual size. I then discovered they do it on purpose 1) to save a bit of money and 2) so that the finish drill hole wont be oversized. Getting to the actual size is done with reamers $$$!
Why stainless steel tubibg cant be acurately sized, I dont fathom
and why I cant type on the ipad without making typos - Intry try to catch all of them before hitting post...
