The Karebac Rotary Interchangeable Back Up has made my work so much easier! Thanks to my knowledge gained in practice, I can say that this product is highly efficient and saves me a lot of time on my industrial projects. The easy interchangeability of the pads makes my work efficient as well as cost-effective. The only con is that the price is a little on the higher side, but the product is worth the investment..
Definitely too high a rotation speed for grinding parts. It's more like a meat grinder. I'm sure it worked fine, just not for my intended purpose of sanding parts.
Pros
