Using the DeWalt DWA54380 rebar cutters is easy. First, make sure your drill supports SDS Plus shanks. Then, insert the cutter into the drill. If you need to drill through tough rebar, you can switch to hammer mode thanks to the durable head design. When you want to use a carbide bit for other tasks, just use the SDS+ shank to switch tools quickly. As for maintenance, after each use, clean the cutter with a dry cloth to remove dust and debris. Store it in a dry place to prevent rust. And always wear safety goggles when using this tool to protect your eyes from flying particles.
