How to Drill through a Brick Surface
If you are going to drill brick surfaces in your home, you should consider it seriously as it requires thorough planning and special care to prevent damage. This is especially true if it is your first time doing it. The reasons for drilling a hole through brick include getting a cable or pipe through because there is no other way to get them into your house.
Step 1 – Assessing the Job
Determine first the size of the hole you are going to drill through brick. Usually, it should be quite bigger than the pipe or cable that you are going to install through it. You should also determine the length of the drilling that is required, which would give you an idea of the drill bit you are going to use.
Step 2 – Purchasing the Masonry Bit
Once you have determined the size of the hole you are going to drill, verify if it can be handled by your power drill. Some bits are too large for some drill models. If you require a larger hole, you might have to purchase another power drill as well. You will also have to buy a smaller bit for drilling a pilot hole. Ensure that the bits are long enough for your task.
Step 3 – Assessing the Hole Location
Find the exact spot where you are going to drill the hole. If it can be done, make a hole through the mortar that is between bricks rather than on the brick itself since it is much easier. There is less likelihood of cracking the brick and your drill will have less wear and tear. Make sure that there are no obstacles along the drill path such as electrical wires or pipes which were installed inside the walling.
Step 4 – Ensuring Safety
Have a small can of water on hand. You will need it to cool down the bit. Wear your goggles to protect your eyes from flying debris that will result from the drilling.
Step 5 – Drilling the Pilot Hole
Drill a pilot hole first if you are going to make a large hole using the small drill bit. The pilot hole will aid in guiding the large drill bit.
Step 6 – Drilling through Brick
In drilling through the brick, a few seconds with short breaks in between is better. During the break, immerse the tip of the drill bit on the can of water to cool it down. This is because brick and mortar generates a lot of heat when drilled with a power tool. Drilling for a few seconds and then taking a cooling off break will ensure that your drill bit will last through the process. You should also make sure that your drill bit does not get stuck on the brick, which is another reason why you should drill for a few seconds at a time only. A stuck drill bit would be a big problem on the project.
Step 7 – Drilling the Hole Itself
Once you have finished with drilling the pilot hole, change your drill bit to the appropriate size and drill through the pilot hole you have made.
Step 8 – Sealing the Hole
After the drill goes through the brick, push the cable or pipe through it and seal the hole with a plumber’s putty.
