NSK Air tool Question

Somewhere I read that one of ourt members is using the NSK Aqua for piercing. It apparently sprays a fine mist of water on the piece being turned.
My question, is the tool better with the water or just used dry?

I've been waiting for over a week for a replacemet tubine from powercrafter and I need to finish a piece of work for a gallery. I,m just frustrated enough to just get a new, but different, tool.

Since the NSK is designed to be a dental tool, the water spray is for dental use and would require a water hookup. I use an NSK tool and certainly wouldn't want to spray water on a piece that I was piercing. Raising the grain would create quite a mess.

Thanks for the reply Wally. The reason I asked the question is because I read one of the posts stating the NSK was water cooled. It didn't make sense that one would spray water onto a wooden bowl, hence the question.

It took me a while on the NSK site but I found a reference to turn off the water option and lead me to conclude that water was not a souce for cooling the bearings.

Thanks again for your response.
 
Jim,

NSK has two different models. One shoots the water out (used for dental work) and the other is an air only unit with sealed bearings. I own the latter and it is the ONLY think I would use for piercing....now. Kinda expensive at $400-500 if you need to buy a regulator (it doesn't come with one and you MUST have one) and a few carbide bits.

Most of them don't need to go over 40 PSI. A regulator with a low end fine adjustment is the most handy. I have a kinda cheap one that works, but it can be a challange when a fine adjustment is needed. Once it's set thought I just use the on/off valve. The powercrafter needs to be oiled if you want it to last. I've had mine over 4 years without any problems, thank god, but I keep it up and I don't try to hog wood with it. I have other toys for hogging.

Absolutely DO NOT exceed 40 psi. I have mine set at 35 psi (recommended) and its works super. I learned the hard way what too much pressure will do to a $139 turbine. I didn't know it but I was supplying mine with 65+psi and it blew all the oil out of the SEALED turbine. Oooops! Now I have a PSI gauge and everthing is working peachy. Having a water filter is also a must. You don't want humidity filled air flowing through this precision tool.
