The hardware store sells these bits for about fifteen dollars each. So far I've only needed one angle cutter (photo), but thought why not upload a few that I might need later (carpenter's motto). The chamfering chisel is a good test because it gets to the point. In my experience these thin points can ruin my hardwoods/knots. I've gone over 100 feet of pine and 16 feet of oak with a full bevel and the top is still like new. All in all a great purchase. Don't be fooled by the onsite shop.
