Bit size wrong

Like others have said. The bit is too large. I had to go to another supplier to order a 11/32 bit. Penn State doesn't seem to offer one. Weird. Otherwise I love the chuck.

Wonderful Time save

This is the type of innovation that makes turning even more pleasurable. Saves time and guarantees perfect centering along with a secure anchor to turn on. Joe

bottle stopper chuck

Chuck does it's job smoothly with no run-out. Lost one star because the drill bit supplied with the chuck (23/64") is a little too big. An 11/32" bit works much better, or a drill and tap is ideal. I would recommend it.

Nice product

easy to use. nice and included instructions

Good Chuck

The chuck itself works really well. The drill is the wrong size. The turning will not tighten on the chuck and elongates when turning. I needed to go to a smaller size. It then works OK.

Okay, but

The holes drilled to 23/64 did not tighten onto the chuck. I drilled to 11/32 and then it worked great.

Bottle stopper chuck

I have a competitors chuck and just threw it away. There is no comparison. Penn States is of superior quality and construction. Thank you for always looking out for your customers and having the best items on the market!

Bottle stopper

The drill bit that is provided is too big. Use a smaller one and it will work as advertised. Penn State should fix this discrepancy as I've seen other complaints that are the same. I almost had a blank that would have been useless had I not filled the hole and started over.

love this mandrel

I'm back to buy my 2nd of these after finally wearing out the threads on my first one. It took close to 300 hardwood stopper blanks to kill the first one, so it's obviously a fantastic value.

Makes it like a pro

Very easy to use as I'm just a beginner. Perectly centers the stopper for a great piece every time. Great value for the price. Liked it so much I ordered another one.
