Is there 1 blade for my angle grinder that I can use to cut both asphalt and paver bricks for my walkway?

Question

I am going to be laying a brick paver walkway (not large), and because of the curve pattern I am trying to attain, I will have to cut a few bricks (non-traditional cuts - i.e., not just cutting the bricks in half). The asphalt edge of my driveway will also need to be trimmed as it flares out at the bottom. The bricks will be perfectly flush along the length of my driveway, so I have to cut it perfectly straight down the length of my driveway (about 12 feet).

I have an angle grinder I want to use to cover both of these tasks. Is there 1 blade I can buy for my angle grinder to achieve both of these tasks? I understand that I will be meticulous in measuring and marking my cuts for the bricks and asphalt, but I want to find 1 'proven' blade to do the trick. Thanks in advance!

Answer 1

It will not work using an angle grinder.  First of all, it is too small.  Secondly, if you used a diamond blade, which would work fine for the pavers, the heat generated by the blade when attempting to cut asphalt would immediately melt the asphalt and gum up the works.  

What you need to do is to go to your rent-a-tool place and rent a contractor's wet saw made for cutting pavement.  You need to use a wet saw to keep the blade cool so the asphalt does not melt.

The bricks you can cut fine using a diamond blade, but instead of trying to do this with an angle grider I would get a 7 1/4" diamond blade and cut the bricks using a circular saw.  You'd have better control.

Answer 2

yes! i use a diamond blade. it should be called a masonry blade in the store, and its a segmented blade made of metal and has little diamond chips on the blade itself. works great

Answer 3

depending on the diameter of the cuts i think you might find it difficult to " cut " the brinks and asphalt to the proper shape. if they will be large radius' you should be fine. but for tighter corners i would use grinding disks made for granite. you can find them at marble and granite sales locations. then you can cut the bricks to the right length and " grind" the edges to the proper curve. trying to cut an interior angle with any blade would prove difficult as the blade will not want to flex.
