Using the Bosch RC2084 is straightforward. First, make sure your rotary hammer is in rotation mode. Insert the bit into the SDS - Plus chuck of the rotary hammer. When you start drilling, the unique flute geometry with a steep spiral will quickly remove debris, so you don't have to worry about clogging. The high - quality carbide bit will last a long time, but it's still important to use it at the right speed and pressure. As for maintenance, after each use, clean the bit to remove any debris. Check the relief hole to ensure it's clear for proper heat dissipation and slug removal. Store the bit in a dry place to prevent rust. Also, always wear appropriate safety gear like goggles and gloves when using this rebar cutter.
