This fake works quite well but is very noisy. I recommend buying well made sanding belts as the cheap ones that come with the tool are POS only (a piece of shxt). You get what you pay for, that's the fable of the day!
Pros
Purpose: Great all round tool for grinding sharp metal edges, rusted bolts, welds etc. Excellent for removing spot welds. Effective for shading, cleaning grooves and contours.
