Tools and Hardware Reviews of the Irwin Industrial Tools 3041006 Speedbor Max Spade Bit Set, 6-Piece
Tool Review: incorrect product description
Summary: 1 Stars
Irwin makes both Speedbor auger bits and Speedbor spade bits. The pictures are for a auger bit but the description states that these are spade bits. Big difference between the performance of the two types.
As noted the Irwin Speedbor bits die if they hit a nail. Better if is this is a concern to use one of the Greenlee Nail Eater auger bits. One of the advantages of a hole saw or big gullet hole cutter is that all the material is not removed and the chance of hitting a hidden nail head is greatly reduced. Big gullet hole cutters also require a less powerful drill - important if drilling through very hard wood like oak or ipe.
Irwin auger and spade bits like these also have relatively short shanks which limits their use. There are "installer bits" that can be 30" long or longer and are awkward to use but a few companies are also making 17-18" long auger bits which provide excellent cutting depth and are easier to use than the installer or bell hanger versions.
