How to cut concrete block with a circular saw
If you can find the same size arbor (hole in the blade) it works great. A thin blade uses less horsepower but won’t last as long. Make sure to blow the dust out of the motor after done as it will shorten the motor life if left in the motor.
I do this with a table saw and skill saw for brick and cinder blocks when I want a clean cut. Also wear a dust mask you dont want to breathe the dust.
