Drilling Through Reinforced Concrete Floor

When your concrete drill bit hits rebar you should stop drilling and replace the concrete bit with a metal bit.

Drilling through reinforced concrete floor.

It creates holes without causing aggressive demolition or too much strain. We show you what you have to look out for drilling in reinforced concrete and which tools are well suited. Concrete drill bits are the right choice for drilling through reinforced concrete. Don t let a concrete wall or floor stop you from completing your project.

For a standard 1 inch bottom wall plate if you were using inch by 2. Once you have the right drill and drill bit mark the spot on the concrete you want to drill through. To drill into concrete use a hammer drill with a carbide tipped masonry bit. Drill for maybe 30 seconds then pull the bit out of the hole.

Older concrete however is often much more dense than some of the cosmetic concrete used in modern finishes so boring through a 50 year old concrete foundation with your old school rotary drill. It is far better to do the drilling in small increments. A hammer drill takes the hard work out of the job as it hammers into the concrete as it drives doing the work for you. Bosch offers a bit for drilling lightly reinforced concrete that has dust extraction built into the bit itself in an attempt to minimize the production of the hazardous dust.

Next turn on the drill s hammer function and start drilling applying firm but not forceful. Then drill a shallow pilot hole using a low speed or short bursts. The sds max 9 speed clean features two extraction holes at its head which connect to an internal cavity leading to a vacuum connector. The core drill is a highly efficient and powerful tool for boring holes through reinforced concrete block brick masonry and stone.

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. Drill through the predrilled holes in the wood and into the concrete to a depth inch deeper than the screw length.
