    • 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

    • Wow!!! Very pleasant surprise
Size: 6" 6-Jaw
I honestly was not expecting much out of this chuck. I figured it was just another knock off, inaccurate import, I was very wrong, very precise , works great. I don’t know how I got along without it.

    • 12 thou total runout
Size: 6" 6-Jaw
I bought the 6" 6-jaw chuck and a backplate for my South Bend 10L. The backplate threads were a mess but I had a 2 1/4 x 8 tap and cleaned them up. The chuck was full of grinding grit as expected at this price and I took it apart and cleaned it. When mounted on the lathe the lathe body had about 3 thou runout - not great but OK. However I put various size ground bars in it, and all show 11-13 thou runout - so I'm returning it. Disappointed! ... show more
