JNYLLN Z011 3-Jaw Lathe Chuck, Mini Lathe Chuck with Connecting Rod and Short Sticks, Self Centering Wood Turning Chuck, Power Lathe Accessory

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 3-jaw is ok for low precision work but you get what you pay for here. One thing people do not know is that the installation sequence for the jaws depends upon which side you are going to have facing inwards. Mine was shipped with the sawtooth grabbers facing outward and this uses the install sequence of A,B,Cwhich is stamped on the mount as well as the jaw teeth. If, however, you are going to use the sawtooth jaws facing inward, then the sequence is backward, so Jaw C goes to A slot, B to B slot and A to C slot. Otherwise, jaws will not be spaced properly and will not close completely in the middle. Hope that helps.

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 put something in the jaws and started turning it. Within 20 seconds the chuck shattered.
