I purchased these plug cutters recently to plug top screw holes on my floor installation. A plug cutter is a plug cutter right? Well not exactly.The hardwood floor I was installing included a White Oak border that was top screwed and plugged. I had a [hard] of a time making high quality plugs. The plug either broke off in the plug cutter (too short) or they burned leaving a visable ring on the floor.With my drill press set at a very low RPM I was finally able to make plugs that didn't burn but only when I used very tight gained plain sawn stock. By the time I figured out exactly which speed and which stock was best, the cutter was dull and produced burned plugs again. Argh!I ended up going to a local Woodcraft store and buying a [other tool] plug cutter. With its 4 cutting surfaces this cutter worked like a champ. Had I only spent the extra money on a high quality plug cutter I would have saved myself hours of aggravation. What's your time worth?
