I bought a 450,000RPM

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.
