Query: Great bits

Very sharp. When used with a drill press, it bites into the wood immediately, so be careful. Also, when using free hand with a portable drill, don't let it snatch the piece of wood out of your hands. I have used these numerous times, and are grateful that they don't skip around on top of the wood, especially hardwoods. I actually use a tiny pilot hole when I need precision, as the bits dig in to whatever depression there is on the wood. Highly recommend.
