UHS Air Turbines
We carry ultra-high speed tools from Turbocarver™ and NSK (not available online). These tools will spin 1/16" dental burs (often called "FG" or friction-grip burs) at speeds between 320,000RPM and 400,000RPM (there is virtually no difference in cutting ability anywhere within this range). At those speeds, you can carve almost any material - including wood, most metals, glass, antler, bone, even stone and eggshell!
