This Auger Bit is used to drill holes in your floating shelf for the bracket rods. They are sized appropriately as to fit inside our provided drilling jig and drills the perfect size hole so your bracket fits very tightly inside the shelf.
First, select the dimeter size depending on the type of bracket you are choosing. The 9ER brackets need a 9/16" diameter auger bit. Both the Standard and Mantel brackets need a 13/16" diameter auger bit.
Second, select the length depending on the bracket rod length that you are choosing. The 4" and 6" bracket support rods need a 7" length auger bit. The 8" bracket support rods need an 18" length auger bit.
