Review on Dynabrade 59013 Self Generated Dynorbital Spirit Diameter by Chris Hernandez

This is a grinder. Made in the USA, slightly lighter than most grinders of this type and with a self-generating vacuum. Works great. It costs a little more but is generally cheaper (taking into account lifespan and rate of stock removal). Requires oil in air line or frequent greasing - so not for bare wood work (oil must be removed from wood after sanding), fine after some finish has been applied. The light (over) heavy plastic case makes overhead work and the user easier overall.
