SKU: 152986B 30 Caliber Cartridge Click Pen Bushings

Bushings: Bushings are needed to turn the project on the pen mandrels we offer. The bushings are used to size the outside diameter of the workpiece correctly for the specific project. They are also used to adapt the pen mandrel for project tubes larger than the mandrel shaft. Only one set of bushings are needed for many kits. After the bushings are worn down from sanding they will need replacing.
