    • Cheap alternative to far more expensive 6-jaw chucks
Size: 6" 6-Jaw
It was a far better build than I expected. Like many others, I had to disassemble completely, remove a significant amount of grit and crud from the device, reoil, and assemble it. This will not be utilized on a lathe. I am mounting it to a pallet system for my CNC mill.

    • SAN OU / CME 6" 6-jaw plain back lathe chuck - much better than expected
Size: 6" 6-Jaw
I bought this chuck for working with thin-wall cylindrical workpieces hoping the runout would be better than what some reviewers had reported. I received the unit, completely disassembled, de-burred, re-lubricated and re-assembled it, about an hour or two well spent. I left about 0.001 allowance on the backing plate registration boss and indicated the chuck in before tightening the 3 mounting screws. Doing that eliminated about 0.0005 initial runout. In practice runout at 3/8” work diam. is less than 0.001, runout at 3/4” diam. is less than 0.0005 (!), and runout at 1.25” diam. is less than 0.0015. Of course, it depends to a degree on which pinion(s) you use to tighten and how you set the material in the jaws but if I’m willing to spend a couple minutes with an indicator I can get really good results. Overall I’m pleased with this chuck. SAN OU is a large Chinese drill and lathe chuck manufacturer. I have two other chucks made by this company and neither is as good as this one. Due to variability in sample quality I'm sure your mileage could vary from my results. ... show more
