This has worked great in my Bridgeport factory for cutting 3" holes in 1/2" cold rolled sheet metal . Saves a lot of time compared to using a drill tool. The tool is sharp and cuts fairly quickly with coolant. I have sold these core drills and bought a whole family of large sizes and use them on my mill and lathe.
