As a result of my tests I determined that this product is not up to par .The Sanding Wheel Drill 2 Inch Diameter claimed to be an abrasive mounted point, but it failed to sand even the lightest materials with ease. I found this Industrial and Scientific product to be faulty and unreliable. The only positive was its small size. The negative is that it was a complete waste of my money. I do not RECOMMEND this product for any serious sanding applications..
