Cutting 10" x 3" in my brick siding
 
I'm looking for advise on how to cut a 10" (w) x 3" (h) in my brick siding. The brick is about 4" deep.

I started drilling a 3/8" hole in corner of the cut out from inside the house with my dewalt 18V cordless hammer drill but it's slow and tough going.

Should I continue drilling and make a perforated line and then chisel out my cut out?

Should I mark my cutout and use a 9" angle grinder with a diamond blade make this cut?

What are my options?

Do I need be concerned about re-supporting what I am cutting out?

Dont waste any more time with the drill. You really need a quickie saw with 14" diamond blade. As far as structural integrity, the only time you need to worry is when your using a hammer and chisel to remove the bricks and mortar left after cutting. Sometimes other bricks will break their bond with the mortar which can cause more bricks to come out. If you feel like your gonna cause more damage than is worth it consider hiring professional. For now, the grinder should get you where you need to be with precision, calculated cuts.

Ideally, you can move the hole around a little so you only need to take out one full brick & a partial. Your method of drilling, grinding, and chiseling will work. A 14" cut-off saw is far too big for what you're doing.

I assume you're drilling through the mortar and not the brick. If you are taking out one whole brick, drill/ grind/chisel into the mortar joint above the brick, and then work on the joint below and with a bit of leverage with the chisel, it will eventually work loose.
If you are cutting out 2 adjacent half-bricks, that is more difficult as the bricks will be harder than the mortar. Still work on the joint above, and then cut out the vertical mortar joint between the two bricks. Finally, get a 4" chisel on the centre of each brick and with sharp blows they will crack and come out,
Agreed that a 14" blade is too big for a job like this.
This is one of those jobs where you just need to be steady and patient.

I can see how you would consider a 14" saw overkill but the WHOLE point of using it would be to cut all the way through the bed joint top and bottom so you dont have to beat on the brick so hard to get it out and risk breaking bond on the surrounding bricks. Everyone has their own idea of how to do things i guess. Just glad my ways have never failed me. Good luck with all this conflicting information DIYer

I can't believe the Roman's were able to make it work without a gas cut-off saw..............:whistling2:

TRUEPRO,
I'm sure that your ways work for you as a pro, but remember that a DIYer probably has to go and rent a 14 inch cutter and also has probably never used one so he might make a few cock ups with it.
I often make the same mistake when giving advice to a DIYer, forgetting that they don't always carry the tools round with them and are not always familar with using them.
