As the title says, what RPM setting do you use with your rotary tool for drilling/sanding/grinding plastic parts? I'm looking into buying a rotary tool, but have read in several places that the lowest setting on most tools (5,000 rpm) is too high for use on plastic and will melt it. Is that true? If so, how do you slow down your tool to the right speed, or what tool do you use instead?
Thanks for you advice!
