Review on Tungsten Carbide Titanium 💎 Plated Plastic - ASNOMY Enhanced by Dang Esq

Very disappointed I bought this specifically to drill a 2" hole in a 4" cast iron toilet to fit the new flushing adaptor, it actually drilled the hole. But hardly. A hole and all carbide tips were destroyed. However, the description said it was designed to cut heavy metals. For single use only, I think I can use the mandrel and drill bits with other hole saws so it's not a total waste. Otherwise I would give one star
