Z011 4-Jaw Lathe Chuck, Mini Lathe Chuck with Connecting Rod and Wrench, Self Centering Wood Turning Chuck, Power Lathe Accessory

If you don't need precision and enjoy trying to hold onto a wobbly out of center tool then this is the tool for you.

I was pleased to receive the adaper for the chuck to fit a regular drill if needed.

I bought this to use with hand drills and a benchtop drill press, with the goal of holding larger stock than the drills' chucks can accommodate. So far, this little chuck has performed admirably, effectively holding wood, plastic, carbon fiber, aluminum, steel, and stainless stock, while running at up to 3000 RPM. Most tasks have been light duty, such as sanding, polishing, and chamfering, but I'm pretty confident it'll hold well for heavier duty stuff, like machining small profiles, if I add a tailstock. Quality is actually much better than I was expecting at the price, with a clean die casting on the housing, reasonably precise machining of the jaw channels, and deburring of the machined edges. Adjustment and tightening is smooth and the jaws have very little play when loose. Centering is precise and runout is minimal (even on long stock), and while it's probably not suited to true machining work with high feed rates, it's excellent for how I'm using it. Finally, it is nicely compact: 48mm (1.9") diameter, 21mm (0.825") height, with 8.4mm (0.331") wide jaws.[UPDATE] Six weeks in, I’m still impressed. The chuck holds stock securely, and it runs straight/true. I get a little bit of runout, but since I’ve got a daisy chain with the drill’s chuck and this chuck (and it’s 6mm/.25” arbor/shank) , I think that’s more than understandable, and not a fault of this chuck. I’ll probably replace the arbor/shank with a larger version (honestly, it’s as simple as buying an M12x1.0 wheel stud), which will help with runout and allow the unit to withstand more radial force. When gripping the inside diameter of something like a pipe, the chuck does grip nicely, but you have to be careful to not put too much radial force against stock that isn’t supported (i.e. like a tailstock); the jaws are small, so this is acceptable.

This came with a couple of burs in the bearing surface and when I tried to scroll the jaws in and out it bound up so bad that the thin edge between the jaw slots cracked. The tiny metal pins for adjust the chuck were basically useless after it started to bind and I bent both of them with the chuck in my hand, no vice, no drill chuck, no tools but the lathe chuck and the adjustment pins. If you decided to get this anyway take it apart completely and de-bur everything before you even try to work the action.
