Review on CARBIDE TIPPED HOLESAW 3 3 4 by Kory Shelton

I was drilling through an old ceiling with a layer of plaster, then wire mesh, another layer of plaster and then a plank of wood made to look like a wooden floor. I burned my first club on the first hole. Got a carbide tip and made 20 holes in the Easley. The end was still tough. Holes cut easily and cleanly. The bottom layer of the ceiling was sheathed with drywall. The drill that cut through the hard layers also cut through the drywall layer cleanly.
