I bought this set of punches and a Fastcap flush drill in hopes I could hide the mounting screws on the back of natural birch cabinets. The hole punch makes a very well-made impression and cuts clean discs from real wood edging tape. However, the notch cut with the Fastcap concealed drill bit is a bit oversized. This leaves a small ring around the wood disc when it is inserted into the recess. I think it's better than looking at the PowerHead screw heads, but I expected more. This tool and mud drill appear to be very well made and should last a long time in production use. So I'm surprised the resulting fit isn't better.
