Using the Makita 199081-0 cutter blade set is easy. First, make sure you have the Makita Cordless Threaded Rod Cutter model XCS03Z. Install the 3/8-inch cutter blade set quickly and easily. When using it, place it on the threaded rod you want to cut, preferably for overhead cutting. The blade will make spark-free, clean, and burr-free cuts, allowing you to easily hand-thread fasteners or nuts. As for maintenance, keep the blades clean after use. Since the cutting dies are reversible, you can flip them when one edge gets dull to double the blade's lifespan. Remember to always follow safety guidelines when using power tools. Also, check the blade regularly for any signs of excessive wear and replace it if necessary.
