Using the Bosch RCSS2124 rebar cutter is easy. First, make sure you've got a standard three - jaw chuck drill or a hammer drill. Then, insert the straight shank of the cutter into the drill. This cutter is only for rotation mode, so don't use it in hammer mode. It cuts 36% faster and lasts twice as long as other cutters, which will save you time and money. When drilling, the unique flute geometry with a steep spiral will quickly get rid of debris, and the relief hole will help dissipate heat and remove slugs. After use, clean the bit to keep it in good condition. Also, store it in a dry place to prevent rust. With high - quality carbide, it has a long lifespan, but gentle handling will make it last even longer. The tapered body design makes it lighter and allows for smoother drilling, so enjoy a hassle - free drilling experience.
