For construction industry or house renovation, Drilling Concrete is UNAVOIDABLE. When drilling a hole into concrete, there is a high chance to encounter the concrete-embedded rebar. The rebar steel can be an obstacle for a standard hammer dill bit to drill through.
Before, people would drill another hole to avoid the rebar when they encountered it. Now, you can use a Rebar Cutterto drill straight through the rebar embedded in concrete without relocating holes.
