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.

Very good tool, runout was only .002 thousandth installed out of box. Very good for what I use it for. Neighbor bought a 4 inch to expand centrifugal clutches , I had to machine jaws thinner for unique tool use. The 4 inch was so nice it caught my attention so I ordered a 6 inch to put on one of my small lathes.

The chuck seems solidly made. When I went to mount the provided mounting plate using the provided screws they wouldn’t match up. I tried every combination of screws in each hole and turned the plate completely around. The end result is I retapped the threads and used better screws to get it aligned. Works good now

Hola, el mandril no lo recomiendo para nada. Al abrir o cerrar el mandril se atasca, tuve que desmontarlo entero para limpiar las virutas de mecanizado y limar todas la arista ya que tenían rebabas, aun así no se abre ni cierra con suavidad, incluso lubricando todos los elementos. Lo peor es que la parte trasera del mandril es de plástico, la concentridad varia en unos 0.5mm.

I was disappointed how rough the action was out of the box. Although it was very well oiled externally, when I disassembled it to determine why it was so rough I found surface rust on the scroll and the bottom of the jaws. After removing the rust and lubercating internally and softening rough edges with 2000 grit sandpaper it operated more smoothly. It runs true and I would probably buy it again. Just a little bit disappointed in the initial quality out of the box.

It’s a nice Chuck for the money but mine had about 10 thousand runout. I converted it to a front mount set true now it it runs true. The plastic back plate when fully tightened made Chuck jaws very hard to open and close. I had to machine down the thickness to keep plate from rubbing on back plate.

the chuck comes with so much swarf in side it it had to be completely stripped and cleaned once all cleaned and lubed up it works great if my apprentice did not clean up job I would say something hope it lasts a while as it does the job really good cannot complain
