Review on Mgtgbao Masonry Concrete Plastic Tungsten Cutting Tools in Industrial Drill Bits by Jason Lockwood

I received these stone beds, they come in 5.5mm and 5.6mm sizes. The tips are extremely sharp and I especially like the hex bases to connect to your drill so you don't have to worry about the drill slipping off. They come in a nice case to keep them organized in your tool box. I'll update how well they cut after a few uses to see if they hold up to real world testing.
