Review on 🔧 Masonry Carbide Drilling Ceramic Plastic: The Ultimate Versatile Tool by Jamar Gow

If you want to drill through glazed ceramic or glass, these drills are an option. I think the serrated design (plus duct tape and your patience) makes for cleaner, more accurate cuts. One of the disadvantages of the grooved design is that you can't get the bit back through the hole you just made. So when you've punched the hole, loosen the chuck and drop the drill bit into the hole.
