POST HOLE DIGGER STEEL BLADES 48" WOOD HANDLES. This Post Digger by Ames is used to dig deep holes below the ice line. Its quality makes it the number one choice for coinage excavators. It comes with 48" wooden handles and steel blades that make digging in drier, rockier soils easier. Unlike other conventional excavators, its high-carbon steel blade better attracts dirt and the oval-shaped notches make the blade more rigid. Its extra-large hinge bolt increases durability and its handle mounting bolts with external nuts help tighten the product.
