How to Drill through Rebar in Concrete: Step-by-Step Guide?
Put On Your Safety Gear
Mark the Spot Where You Want to Drill
Using a felt-tip marker, mark the spot where you want to drill through the rebar in concrete. To ensure that you have plenty of clearance for drilling into the hole, make sure that it is at least 1/2 inch from the edge of the rebar.
Select The Right Bit Type For The Job
The type of bit you select for this job will depend on what kind of material you plan on drilling into: Concrete, Steel Rebar, or both. If you are only drilling into concrete, then a masonry bit will do the job. If you’re drilling through concrete and rebar, however, then a carbide-tipped drill bit is your best choice for getting the job done right.
Secure The Bit In Your Drill
Once you’ve selected the proper bit for the job, secure it firmly in your drill using either a chuck key or an adjustable wrench. Make sure that the bit is locked in tightly so that it won’t slip out when you start drilling.
Start Drilling At A Low-Speed Setting
When drilling through a steel rebar with an electric drill, it’s important to start at a low-speed setting. This will prevent the bit from overheating and ensure that you don’t break it. As you drill, slowly increase the speed as needed to effectively cut through the rebar.
Cut the Rebar
Once you’ve drilled through the rebar, use a pair of bolt cutters or a reciprocating saw to finish cutting it. To do this, put the cutting tool on either side of the rebar and squeeze or saw back and forth until it is completely cut through.
Clean Up The Area
Once you’ve finished drilling and cutting through the rebar, clean up the area around your work site to make sure no hazardous materials are left behind. This will ensure that everyone in the area remains safe from any potential hazards [1].
