After trying this industrial drill bit kit, I am thoroughly impressed with its strength and durability. The diamonds really make a difference, and the steel shank is incredibly sturdy. However, the price may be a bit steep for some users. Overall, the Toolocity CBKIT1 is an excellent investment for anyone needing to make precision cuts in tough materials.
Pros
Gives fast and efficient results for concrete grinding and polishing.
Cons
Expensive option compared to other similar products on the market.
Works great. There is a little learning curve. You should start at about a 45 degree angle so you only drill about 1/4 of the bit. Then slowly bring the drill to a vertical position and it will stay where you want it. I've drilled through 5/16" porcelain tile with the largest bit. This took me 3 to 5 minutes. I stopped every 15-20 seconds to squirt water onto the surface.
