Review on Imachinist S80121014 Bi Metal Blades 14TPI by Draven Invert

cut cold steel fan blades 5 inches long and 3/16 thick, cut first blade out of four and cut like butter, cut second fan blade maybe in 3 inches He stopped sawing, checked the side saw, everything was fine, looked at the broken teeth of the saw blade. very disappointed in blade quality, $19. don't use it. 1 star for the packaging. $19.00 off
