About this specialty power tool
This is a cordless 18V lithium-ion lockbolt tool from Milwaukee's M18 platform, sized at 1/4 inch and built around a brushless motor. It is a specialty power tool, and the model is 2661-20. The listing is for the tool only, so no battery or charger comes with it. It suits someone who already owns M18 batteries and wants a compact lockbolt tool for their kit. Before buying, confirm you have an M18 battery and that the 1/4 inch size matches the work you plan to do. Check the configuration as well, since this listing is for the bare tool.
