Review on Enhanced Performance with Spyder 600044 Rapid Eject 4 25 Inch - Unleash Speed and Precision! by Anthony Cornelius

I bought this to cut holes in concrete blocks. I'm telling you, this is an AMAZING tool for the purpose! I stood on the stairs and worried about how much pressure I would have to put on the concrete. I'm not kidding when I tell you that I used moderate pressure with an 18 volt cordless drill with a porter cord and pierced both walls of the block on one charge in less than 20 minutes. The holes were smooth and very clean. The pilot drill worked great and the core plugs popped out with ease! I went and was stunned because I just knew it was going to be hard, but it was very easy! Tools must be!
