I do high end finish carpentry in Central California. I purchased a used twenty year old kit from a friend some five years ago, and have bored over 150 doors with it. I am just now getting around to changing the bushings and upgrading to carbide bits. I look forward to a tuned up kit, and have no doubt this kit will be boring doors for a long time to come. As there are aspects of finish carpentry that I enjoy far more than boring doors for hardware, I am not ready to say that this kit makes boring doors fun . But it sure as hell makes it easy, and quick. And that means I get to spend more time on the aspects of finish carpentry that I do find to be fun .
