Mini Lathe Chuck Set, Z011 Extension Three Four Jaw Chuck and Connecting Rod Set, Electric Drill Chuck(Type B)

This thing is really cute yet solidly built. I immediately cleaned out the chips left in from the manufacturer and greased the scroll gear before first use. I like it, it operates smoothly and it clamps solidly enough. The main issue i had with getting the run-out down from 0.006" to 0.003" was the thread insert that goes between the 3-jaw chuck plate and the drill's chuck. The thread is a loose fit and when the nut clamps, it causes an ever so slight deflection. If I had a perfectly flat nut, then it might work, but I don't have one matching this thread nor do I have a way to turn it (which is why I bought this in the first place lol). Overall, useful if you don't need a really high accuracy and are doing something like sanding, turning, facing things. I think I will keep it. It is few bucks cheaper on Alipay but you then have to wait almost a month to get it and if you have issues... well it's just not worth the hassle or time for me, so I say good ol' Amazon sellers are the better choice for sanity's sake. Also, my drill press has 0.002" runout, so that is why I said 0.003" even though you can see 0.005" total run-out. I reclamped on my plastic part a few times and got it down to 0.003 runout TOTAL. Just takes some patience I guess. Better do all machining in one go though because I don't think you will get the same clamping twice.

GREAT FOR CHUCKING A PART QUICKLY IN A DRILL. GREAT PRICE FOR WHAT IT IS. IT IS MOSTLY ALUMINUM NOT CARBON STEEL. NON ALUMINUM ARE LIKELY UNOBTAMIUM. SMOOTH SCROLL CHUCK. SURPRISING MACHINING FOR THE PRICE. THIS IS NOT A PRECISION TOOL. HAS 0.010" RUNOUT AT 1.0". HAS BEEN AWESOME FOR QUICKLY CHUCKING HARDWARE IN A DRILL FOR CLEANING. A LITTLE BETTER THAN ANY GIMICK TOOL YOU DIDNT KNOW YOU NEEDED.

Just as others said, this thing wobbles and shakes more than a square tire! Skip on it, just a waste of money, poor quality, and 0 ability to true or align...

I don't have a lathe and needed to shape a 1" dowel rod into a handle, for a project. A few thoughts came to mind as to how I could center a round object and spin it without a lathe. Then I ran into this mini lathe chuck. It chucks/fits into my drill perfectly and the four jaws clamp down on the Dowel. I'm not sure how I made it in my craft this far without this tool! So simple yet so genius. A lathe is definitely out of the question in my immediate future. This has all the functionality I need and so much cheaper than a lathe.

No instructions. Accidentally opened too far and jaws came out. Had to figure out how to put it back together. Spring washer also not strong enough to keep jaws from working open during use

Doesn't spin true. Sloppy tolerances. Incapable of turning precision parts. Buy something else unless you don't need precision.

I use this to sand and shine coin rings and it works great! I saw a few negative reviews of this product describing it as small and lacking instruction, but it was exactly as described and doesn't really require any instructions if you have an ounce of common sense. So glad I bought it! save me about 15-25 minutes per ring.

"I want to chuck a dowel into my portable drill, but this dowel is too big. I don't care about accuracy, I just want to sand this dowel." This is your chuck, my dude.

Too lightweight to hold anything. An absolute waste of money. Blew apart after first use.
