Review on Hougen Rotabroach Magnetic Annular Cutter by Larry Morris

These cutters do not fit the Hougen HMD150 drill. They were offered for sale at the same time, but they don't fit. Requires Rotaloc Plus cutters. I kept one set for myself (can be used in other existing drills) and returned another set. So I can't directly comment on how these tools are made or used as they weren't the cutters I expected or needed a new drill bit. Perhaps I should have delved deeper into the whole compatibility issue and not assumed that Revane's suggestions are correct.
