Using the Bosch RCSS2104 rebar cutter is easy. First, make sure your drill is a standard three - jaw chuck drill. Insert the straight shank of the cutter into the drill chuck firmly. Remember, this cutter is only for rotation mode, so don't use it in hammer mode. When drilling, the unique flute geometry will quickly remove debris, and the relief hole will help keep the bit cool. After use, clean the bit to remove any debris. Store it in a dry place to prevent rust. With its high - quality carbide construction, it should last a long time if you follow these simple steps.
