When your concrete drill bit hits rebar you should stop drilling and replace the concrete bit with a metal bit. However because builders don t leave any indication of the location of rebar there s always a chance that your concrete drill bit will encounter metal.

Core drilling is one of the most effective non vibratory ways of drilling through reinforced and non reinforced concrete surface.

We show you what you have to look out for drilling in reinforced concrete and which tools are well suited. Drill the guide hole to a depth of 1 8 to inch. First determine the wall thickness by drilling a test hole and ensure that it is not a thin concrete wall 8cm thick it is best to keep the drilling depth 1 2 cm shallower than the wall s thickness to prevent spalling splintering or chipping on the inner wall. The core drill is a highly efficient and powerful tool for boring holes through reinforced concrete block brick masonry and stone.

The sds max 9 speed clean features two extraction holes at its head which connect to an internal cavity leading to a vacuum connector.

Switch to a special rebar cutting bit once the drill hits metal. Drilling into reinforced concrete. 6 x research source slow down and pause occasionally to prevent overheating. Start the drill at its lowest speed for better control.

How to drill into concrete reinforced floors. Reinforced concrete is much more difficult to drill if you need to drill deeper than the steel rebar. Do not force the drill. Concrete floors slab on grade foundations patios and driveways all contain steel reinforcement that adds tensile strength to the concrete and.
