You really can't beat this chuck for the price. I used it on a welding positioner I built, and it performs great. If you're machining super high-precision parts like medical devices, you might want a pricier option.

If you fully disassemble and thoroughly clean it, it can be well worth the price. Depending on the normal size of your work is, it may require boring or grinding. After cleaning, mine had .009-.017” runout. After grinding it, I was able to bring that to .002”. Keep in mind, where you grind it will be where diameter is most accurate and tightening it in the same consistent manner will provide the most consistent results.

Am verry happy, and pleased Witherspoon it.thank you.

Quite happy with this chuck. It seem's to be of quite good quality! Excellet product for price!

well made, a few nicks needed to be stoned out. would have been nice if the back plate bolt holes were counter sunk.

Bonne qualité du produit point faible mauvais ajustement des tripodes et manque de graisse

This is a surprisingly good chuck. When I got it, the first thing I did was disassemble and clean it. There were no chips or grinding grit, but the oil was dirty (gritty?). The only thing this thing needs is about an hour of deburring, every edge was sharp. Using a 1 x 4" dowel pin, I was getting less than .002" runout, both at the chuck and 2-1/2" away. Perhaps not as smooth as the high-dollar chucks, but well worth the price. https://www.youtube.com/watch?v=24qdKJmxrks

Buena construccion del mandril y de las garras intercambiables.Viene completo con la placa posterior para tornos con amarres rapidos aunque en mi caso no sirvio.Lo unico un poco negativo es que esta bastante duro abrir y cerrar las garras.

I am an amateur, home shop machinist. I bought this chuck with the back plate and shipping included for less than $125.00, an outstanding value IMHO. The two-piece jaw configuration was a requirement and the source of some problems that may or may not affect your decision to purchase this chuck. If you purchase this chuck, be prepared to disassemble it and thoroughly clean and lubricate it. This one was FILTHY, but I expected it would be. After cleaning, a precision 0.5000 pin ran within 0.0020" TIR. , well within spec. I trued the back plate mounted on my lathe spindle (70-year-old South Bend 9-A) and turned the register boss to 0.0050" smaller than the register recess in the chuck body. The test pin repeats within 0.00050 after assembly and adjustment. Amazing IMHO! I removed the top jaws and cleaned the interfaces with the jaw base. Upon reassembly, I could not get the chuck adjusted any better than 0.015" TIR. I reground the key slot so the top jaws would actually seat properly. I will regrind the jaw faces under clamping load with a tool post grinder when I get time. In the meantime, I'm using machinable steel top jaws to hold some 2" diameter steel discs for turning, facing and boring on both faces. The chuck repeats within 0.00050" TIR with this configuration. Again, amazing. I would purchase this item again but only if I had time to do the aforementioned rework.

Did not come with screws to bolt to faceplate after trip to Home Depot worked out fine. Good quality for price. Chuck has .002 thousands run out after install.
