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

The media could not be loaded. 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.

Bought so I could spin a 3/4" shaft in some shop cloth to take the diameter down a very small amount. These jaws don't grip the shaft tight enough to keep it from coming loose. When I tried tightening it more, one more more jaws slip off and you have to back them all the way out to match them up again. I can't afford a metal lathe and none of my friends have one. I thought this would help me out. What a waste of time and money.

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.

The images shown greatly exaggerated the size of the chuck it's 1 7/8" diameter

The images show a guy with this on his drill and it's like 5x bigger. There are no dimensions in the description, but the product info saws this item size is ‎5.91 x 3.94 x 0.67 inches for Model: 16177914084567. It is actually 1.75" in diameter. It might be fine for ultra-tiny work, but I hope people read the reviews before ordering.

this mandrel does exactly what it says it does. Worked for me

I found this to be great help for my punch machine. I had read the reviews and they were expecting this to work at high rotation. It is great for my use.
