Review on Valianto Grinder Pneumatic Polishing Engraver by Caleb Quade

Tool oiler leaking. The bottle that came with it didn't have a cap to cover the tip after you cut it open to use. The housing is a bit useless if you don't want to unscrew the oiler from the hose. I have no experience with this type of coffee grinder, so I don't like it (yet?). Used it to split a rusty nut and clean rough spots on 3D printed parts.
