Review on Dewalt DW5440 16 18 Inch Carbide by Joseph Mannasseh

I don't think I could break this if I tried. It cut into my base very well. The end that goes into the drill is obviously designed for a pro-level impact drill, and the notches cause it to be off-center in a standard chuck. I cut the end off entirely leaving a smooth shank to grip my chuck and this is now the perfect standard masonry bit. Love it!
