1. When rebar is encountered while drilling with a rotary hammer and a carbide hammer bit, immediately stop the hammer and remove the bit from the hole (failure to stop could severely damage a carbide hammer bit - regardless of manufacturer’s claim).

2. Remove the rotary rebar cutter after the rebar has been drilled completely through and finish drilling the hole with the rotary hammer and hammer bit.

3. Mount a rotary rebar cutter in a standard 1/2" chuck/drill motor insert the rotary rebar cutter into the hole and drill through the embedded rebar.
