Review on 🏗️ Concrete Masonry Tungsten Carbide Plastic by Daron Ellis

I purchased these bits to install two sets of frameless shower enclosures that required drilling of ceramic tile (NOT porcelain). I didn't expect them to last forever, but the 3/16" drill bit kept cutting throughout the project - about 30 holes. You'll need to cool the drill bit while drilling, but that's pretty normal. I used both bits provided during installation and believe they still have life in them. Also, I have the full balance of the set which is unused at the moment, which I think is important. I'm not sure if I'll try them on porcelain or glass. , although.
