Customer Reviews for K72-100 4" 4 Jaw Lathe Chuck Independent Jaw Wood Turning Design CNC 4 Inch

Bought to put on a weld positioner, works great to be able to weld square to round parts. I took the spring off the chuck end bit the quality seems good.

Great value 4 jaw chuck for the price. It came in clean without much dirt or grime from manufacturing. I only needed to remove the jaws, give it wipe down, and mount it on the lathe. Keep in mind this chuck has 4 bolt pattern for mounting.

My minilathe came with a three-jaw chuck, so I needed a four-jaw for times when odd shaped materials won’t work in the 3-jaw. It came well packaged and completely covered with a machine oil to prevent rust, and it took a bit to clean it all off. The jaws all needed sharp edges smoothed off, and once re-lubricated and assembled, it works fine. Just taking a star off for the sharp edges.

I got this to use on my old Atlas 12 \" lathe. The original 4 jaw is way too big for small stuff. I have a three jaw that I use mostly, but I need something to hold small irregular pieces. This fits my needs fine. I found a backplate on EBAY that just happened to fit PERFECTLY after I received it. Took a fine face cut to insure no run-out. It's typical Chinese quality, But it serves my purpose. Don't recommend for fine precision jobs though.

Br advised that this chuck requires 4 mtg studs. I was unaware and tried to mount it on my three hole back plate??? Need adapter plate or redrill back plate

The chuck is not threaded; so you will need to purchase a threaded plate to attach. Ensure the attachment plate has the correct threads to attach to the lathe. The chuck is of good quality and a strong value for the dollar.

I found the 8.0x1.25 mounting bolts to be Allen bolts instead of allen studs and nuts. Bolts will not work. One had to buy 40 mm long mm bolts and cut them to fit.

This little chuck is a dandy. Overall finish is excellent, and it fits a 4\" rotary table perfectly. Would buy again.

Installed on Vevor MX-S716G lathe. Requires an adapter plate (convert 4 hole bolt mount to 3 hole stud mount) and 3 studs if you want to leave the original studs in your 3 jaw chuck. The adapter is available on AliExpress as shown in attached picture. Note the adapter PN 1692 from littlemachineshop.com will not work because the 3 stud holes are for a smaller bolt circle. Still hard to beat the total cost/value.

It is a great product. Unfortunately I can't use it because I ordered the wrong one for my lathe. I Would like to return it.
