I have bought 10 of these tool holders. Everyone mounts perfectly on my BXA tool post. My tool post came on my lathe new so it's not the same manufacturer. Yet they all hold repeatable height and mount flawlessly every single time. I'm a toolmaker ( tool die ) by trade. I use these tool holders everyday with excellent results. I have so many I have to question other people's reviews. Getting ready to order 2 more right now.
