Review on Toolocity SCB0118D Monster Diamond Concrete Grinder by Adam Bates

Very simple, this core drill works very well. Used dry for an ASTM 4541 Adhesion Test Car Set and drilled properly. My only suggestion is that due to the small ID of the drill, it is recommended that you use a stationary mobile or mounted drill to avoid breaking the core when drilling under 1/2". Difficult to maintain straightness with a hand drill. has nothing to do with the power of the drill as it goes through concrete quickly.
