Review on Disston E0102354 Clamshelled Tri Cut Tungsten by Warren Hess

Drilled 1/2" steel hole in smoker firebox to accept two BBQ Guru Pit Viper fan adapters. The central drill broke immediately, I just replaced it with a quality drill. The hole cutter works surprisingly well. That's a beast. I drilled 2 holes in half inch steel and one hole in 5/8 inch steel. Work slowly with plenty of drilling oil. It's still sharp and cuts through thick steel quickly. I am very satisfied with this product! Take it. But prepare a spare drill bit for the center hole, which can be easily replaced with the supplied hex key.
