Review on 💎 Enhanced BGTEC Diamond Granite Porcelain Ceramic Cutting Tools by Scott Spoja

I bought two packs to drill 8 holes in porcelain tile for a shower door. They work but wear out after about 4-6 holes. . Once "jaded" they tend to run around knocking out a hole, so don't mess around, buy enough bits to get the job done. Start at a 45 degree angle with the drill rotating and make a crescent, then slowly incline to 90 degrees. Grab him. cool slowly and with water.
