Customer Reviews for VEVOR 3-Jaw Lathe Chuck, 5'', Self-Centering Lathe Chuck, 0.1-5 in/2.5 -125 mm Clamping Range with T-key Fixing Screws Reversible Jaws, for Lathe 3D Printer Machining Center Milling Drilling Machine

see no problem with this chuck. Since several reviews indicated a malfunction because of debris inside the chuck, I immediately disassembled it upon receipt. Disassembly was simple. One review stated the jaws didn't close evenly. I think those jaws were removed and were not reassembled in the correct order. I found one small chip inside which would have never caused a problem. The chuck was well oiled, wrapped in plastic, and packaged securely. I am in the process of turning the backing plate, so I can not yet attest as to the trueness of the jaws, but, I don't foresee a problem. The OD of the chuck is larger than 6". It measured 6.424". There is one plastic piece attached. It seems to be a "dust cover" on the back side and has no mechanical function. The jaws are numbered, (1,2,3) but, the chuck itself is not numbered. I plan to just number stamp it myself. I can see this chuck giving years of service. I feel I got a good deal.

This was a perfect replacement for my table to lathe. It was a little stiff, but I disassembled it, a thorough cleaning, and lubricated it. It was spot on and the runout was pretty accurate (within .001"). I'm looking at one of their 4 jaw chucks now...

he quality of the chuck is good, but bought a vevor brand wood lathe and had trouble getting the t bar to mount. Now I have this 4 inch 3jaw chuck that does not have the correct size t handle. I will post a video later. Update, I contacted vevor about the chuck key, and they quickly fixed the problem. If you have any issues, I recommend contacting them because I contacted Amazon about it and it went nowhere.
