Review on Lit Freud DHS2000CT Carbide Hole by Aaron Parish

This is a great hole saw. I have this and another size for a quick change mandrel set. Both cut quickly and smoothly for perfect holes. I've made hundreds of holes with each of them and they both cut the last hole just as well as the first. The hard metal stays nice and sharp. The quick change works very well, which makes the system very versatile.
