I need to cut across my driveway (30 year old cured concrete) to install part of a drainage system that looks like this:
I’m cutting at the expansion joint so one side is done (yea!) so I just need to cut off a piece about 1.5” wide x 3” deep x all-the-way-across-the-driveway. I have a 4.5” angle grinder, but I don’t think the blade will cut deep enough. I have no hammer drill. I won’t be renting tools.
Can I take one of these cheap HF chop-saws and remove the blade portion from the base and use it freehand?
If it’s possible to remove the base and use it freehand I can put one of these 14” diamond blades on (they sell this blade, advertised as for “cured concrete” but I didn’t see a saw it was designed for?)
The cut can go medium-slow, I don’t care if it takes an hour instead of 5 minutes. I don’t care if it has to be done dry and creates a noxious cloud of cement dust that blacks out the sun for most of southern AZ (I”ll wear one of those 39 cent dust masks and a pair of cheap sunglasses.) It has to be reasonably clean – the driveway is already cracked in places so this isn’t a beauty contest, but I don’t want to be breaking giant chunks off either, just straight enough that I can drop the drainage channel in and set with a bit of premixed concrete on the sides/bottom.
Is it do-able under those conditions? Has anybody else ever taken a cheap cut-off saw and chopped off the base and gone free-wheelin down the driveway?
