Bought two holes to drill holes for SOSS barrel hinges. First, I drilled 3/32" pilot holes to center this Forstner bit, but the centering point is too small to keep the drill centered. As soon as the drilling had started, the chisel moved, causing the hole to take the shape of an oversized " oval track". I had to go to the local hardware store and get a shovel that has a much larger spiral tip. This bit drilled the perfect holes for the keg hinges. One was used for an incomplete hole, the other was unused. Returned them .
