Review on Century Drill Tool 77441 Abrasive: Unbeatable Performance and Precision by Anthony Cornelius

I just tried these little animals and found no flaws in their work. This is new to me, I can usually find something that annoys me in EVERY product. I really like it when small metal tips don't dig into my delicate pieces when grinding metal, and as a metal sculptor I can achieve a very abrasive effect. The ability to work fine/medium/coarse is a great detail when working with metals and gives me more options. So buy these things. I doubt you will be disappointed.
