Shaft Diameter Reduction Tool

This is used for reducing the shaft diameter of D-bits safely, minimizing the risk of your D-bit blank whipping. The tool attaches to a quick-change toolpost holder. It employs a bronze bushing, which as many as needed can be drilled to suit the specific shaft OD that you wish to turn, and you can easily swap out the bushing with the tool still mounted to the QCTP.
