Review on 🔩 High-performance Mgtgbao Masonry Concrete Plastic Tungsten for Superior Durability by Rovy Oppeneer

I love that the shank has 3 flat sides to allow the drill to grip it properly. Almost all other masonry drill bits are round, and it's almost impossible to tighten the chuck enough so that it won't slip when the drill bit cuts into concrete. These don't have this problem. And 10 bits for the price of 2 or 3 is a great deal. The seller is great too. There was an issue with Revain shipping, which they fixed at their own expense.
