Anybody use dental high speed air turbine drills for carving and detail
work?

How do they work and do you have a source for them, preferably used!

I was also a tool and die guy back in the 80s. One of my fellow workers had
a dad who liked to experiment with personal dentistry. Borrowed one of
those high speed air grinder (30k+ rpm) and decided to clean up some of his
teeth. I guess heat can be a problem when doing something like this. heh.

In an earlier life as a diemaker I frequently used a high rpm pen turbine
with a rear exhaust. They are a joy to use, usually cutting nearly
effortlessly.

That said, buy a good oiler, a good supply of air tool oil and an air
regulator (along with plumbing bits and pieces to join them together) when
you buy an air pen. Tools running that fast are counting on a steady
supply of oil ... mine wanted 3 drops per minute, no more and not much
less. I mounted my regulator / oiler inside a cheap plastic tool box. It
was a good place to stash a small can of oil, the necessary wrenches,
an assortment of tool bits and the pen itself when I wasn't using it.

I've not used them myself, but know of a number of people who do use
them with good results.

I'll go out on a limb here and say "A dentist?" You can buy them new
from a dentistry supplier, but your regular dentist would likely give
them to you, since they throw them away.

According to my dentist, they are rebuilt, not thrown away. I tried to invite
him to offer me an old one but no dice.

I bought a 450,000RPM angle turbine drill, hose, chuck wrench, and variable speed regulator (foot pedal) on eBay for $100. Used,
but completely rebuilt. Works fine but lacks any torque. Good for VERY THIN wood, but not much power for hogging out things.

Maybe different styles? They're not really that expensive, and I have
a dentist acquaintance who assured me that he tossed his out when they
were worn. I can't remember the name of the dental supply company
whose catalog I used to have, but I bet it would be easy enough to
find one.

Did you put an extra zero there by any chance? If not, _wow_.

That's right, 400,000 RPM. That's the PowerCrafter, which is an air-operated
dental-style turbine drill. It works great for fine carving and piercing, but
it is high RPM, low torque. The high RPM makes it more stable for delicate
carving since it doesn't walk as much as a lower RPM tool like a Foredom. The
low torque means it will stall if not used delicately. The Foredom style tools
(Cable operated) are low RPM, high torque tools and they won't stall when
hogging out large areas or using sanding disks. I have both tools, each for
different applications.
If you want a Powercrafter you can check out TwoPaw studios at Twopaw.com. They
are very helpful. Incidentally, you don't need an automatic oiler for the
PowerCrafter. Just 2 or 3 drops of oil every 30 minutes or so is all you need.
The automatic units tend to over-oil and you get oil all over your hands. It's
very difficult to regulate the oiler to deliver the oil that slowly.

Thank you, sir. I did not even imagine that such things existed.

Nope. It really spins that fast. Do a search on eBay for "dental handpiece" and you'll find alot of them for sale.

particuarly when reading about dental tools. Somehow the thought of my
dentist hogging out a large area causes a bit of a reaction.

This should do the job.

You might want to read the whole thread. Looks like 56,000 RPM is low speed
by dental standards.

This unit is too slow to be compared to a dental turbine drill. High speed
turbines revolve at 400,000 rpms. It really depends on what you intend to
carve. I own a Powercrafter 400,000 rpm unit and like the speed, no wander
caused by hard/soft wood or wood grain.....Ralph
