Question Cutting Concrete Block in Half?

I built a raised garden this weekend using concrete wall blocks (link to them below). Looks fine except that the two ends could each use a half block for a clean look.

Is this something I could easily do myself? Or where could I take it to have it cut?

12 in. x 7 in. Savannah Concrete Wall Block-81127 - The Home Depot



Thanks.

Normally a wet saw is used to cut that. Since you only want to cut 1 block, you could put a masonry blade on a circle saw.

I'd use a diamond blade in a circular saw. If that is to pricey you could use a masonry carbide blade but because they get smaller as you cut you may need a couple. Cut from both sides and if that still isn't deep enough snap with a thin wide cold chisel.

Or just buy a 1/2 block the same place you bought the other blocks.

I doubt a masonry blade on a skil saw would cut all the way thru but if you make a score cut you can use a wide brick chisel to finish breaking it in to. If it wasn't for the lip, I'd just use the chisel.

we just finished a 200' x 6' retaining wall of those things,,, we used a demo saw w/dri-diamond blade but that's because we own 3,,, IF i were you, i'd get a 4" grinder & 4" diamond blade,,, saw ea side 1" deep which is all it will do,,, hammer off that piece & finish w/more saw cuts

If you only have one or two cuts to make operatives look around for a construction site where they are doing ornamental stonework. I'm sure they'll have a large wet saw for their work and if you ask nicely and offered them a couple of bucks I'm very sure that they would cut it for you! Much easier, safer and probably cheaper than trying to do yourself.

I'd use a 4" angle grinder with a cheapo, $3 masonry blade, finishing off with a brickset and small maul.
