The most common reason to drill a brick wall is probably to screw something to it like a batten, molding, hook or bracket for example.
Or you may need to drill a larger hole for a cable, pipe or vent to pass through.
Tools you might need depending on the size of the hole you want to drill and what the hole is for:
You can't use wood or metal drilling bits for masonry, you need specific masonry drill bits.
They are excellent for drilling bricks, blocks, mortar (cement), concrete and some tiles. They are available with a normal round shank like in the picture to the right that can fit in a standard chuck as well as a quick release drill chuck.
If you have an SDS masonry drill you will need specially designed masnory drill bits for SDS chucks.
Generally when using masonry bits you will drill with a hammer action though this isn't always necessary and sometimes better to avoid.
If the brick or block you are drilling is particularly brittle, using a hammer action can actually just shatter & annihilate the material making it impossible to fix to.
If you keep drilling holes but your Rawl plugs aren't biting (the plugs spin in the hole) then this may well be the reason. Try again without hammer on, a slightly smaller drill bit and go much slower to see if that helps.
I won't go any further here as there is much more information on drill bits here so check that page out first and come back if you need to.
There are four types of drill you could use:
Unlike timber that is soft(ish), pliable and whereby you can simply drill a pilot hole to wind a screw straight into it, masonry materials are too hard and dense for that (there are some exceptions we'll get into later). In most instances in order to screw something to a brickwork wall you will need to use Rawl plugs as well.
Colour coded by size, Rawl plugs come in;
For general carpentry work, you will most commonly use red and brown Rawl plugs with 8g - 10g screws that have Pozi-2 screw heads. You can buy assorted boxes of Rawl plugs.
Rawl plugs like these ones have anti-rotation 'wings' to help prevent spinning in the hole too and therefore grip better.
When the holes get bigger and the fixings need to be stronger as you are fixing something heavy to the wall, more heavy duty wall anchors are needed instead.
When you need a strong fixing in brick work walls or concrete, heavy duty wall anchors work in a similar way but can take much heavier loads.
Examples might include fixing a TV to the wall or even a staircase. Generally for applications like these I will choose a Fischer Fixings of some sort. They are available in various lengths and sizes to suit different applications and are seriously strong.
Drilling a hole in a brick wall for these fixings is the same as above but for larger holes I am almost always using my SDS hammer drill with SDS drill bits which is designed specifically for this type of work. It is a heavy duty hammer action drill that can far better withstand the stresses of large masonry and brickwork holes.
To drill a brick for larger holes still, you may need to consider a core bit. Similar to a hole-saw that you would use for timber, core drills are diamond tipped tubular drill bits that cut round the edge of a hole rather than boring right through it. This means they cut the least amount of material to get the hole drilled.
Core drills are more suitable for drilling hole in masonry for pipes or large cables to pass through and are therefore more often used by plumbers and electricians.Kits are available with the most common hole saw sizes you'd need to drill a brick wall for pipes or cables.
