Review on 🔪 LDEXIN Triangle Cutting Tungsten Carbide: Precision and Durability for Cutting Purposes by Tyler Cooley

So, I bought this with a quick idea to cut 2 holes in 3/16" sheet metal. Used a hand drill, kept the bit and steel lubricated, and when he drilled the tungsten bit almost through the steel and snapped the whole bit, 4 tungsten cutters broke completely. Drilling? Still ok and in place so i have to wonder about the durability of router bits you know with a hole saw if you mess up as an operator and the center drill breaks doesn't click and is in great shape i had to order a second bit so i could have the 2nd hole I hope I can get through the second one.
