Toolocity SCB0118D Monster Diamond Concrete Grinder Review

Based on my observations, this industrial and scientific diamond drill bit is a game-changer for cutting through tough concrete surfaces in no time. The diamond-coated tip is strong, durable, and efficient in delivering quality results. Its performance is remarkable, and it saves time and effort when compared to traditional drills. However, the price is a bit steep, and not pocket-friendly for anyone on a tight budget.

I used this drill bit to cut 4 holes in a Silestone countertop for a fine reverse osmosis filter under the sink. Silestone is much harder than granite. I think this drill bit can make a few more holes.

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.
