Used KDK tool holder No. 05156 and KDK 05 for boring bars. Did my best to clean them, they work well. The tool holder has a baseplate/Tee Nut and the KDK 05 has 2 set screws so that it can be flipped and used as well. See pictures for actual item and condition. Please ask any questions you may have and I’ll do my best to answer.
