Drill vs. impact driver, boring holes





I bored two holes through a pressure treated 4×4, using a 1-1/4″ Milwaukee Speed Bore Bit. The first hole was done with an 18-volt Ryobi hammer drill / driver. The second hole was made with a Milwaukee M12 FUEL™ 1/4″ Hex Impact Driver. While the impact driver takes about twice as much time to make the same hole, it requires zero effort to hold the tool steady.
