SANOU K72 Lathe Chuck 80/100/125mm 4 Jaw Independent Hardened Reversible Tool
A part of the review has been auto-translated.
The unit arrived well packaged & protected. No rust issues, but I did have to clean a decent amount of oil & a bit more machine fouling than I believe should be acceptable on any type of part being labeled precision. The chuck mounted up to my existing Little Machine Shop adapter plate. The first item i tossed in the chuck was a piece of 6mm Brass Round Bar & with not much effort I was able to have it centered to 0.0005" My only complaint is 2 of the 4 chuck jaws were not completely machined & they stopped short of completely facing off the face of the jaws. Pictures included will show the facing issue which I will turn & Face again on my own. At this point it is a product I would definitely purchase again in the future.
Real product is way BETTER than displayed one. I ordered 100mm size. Very well machined. But mounting (back) side is different, than on photos - 4 holes 90 deg instead of 3holes 60 deg.
