I need to grind an apron or slope area across a garage door opening. The opening originally had storefront glass in it, so the edge of the slab is flat. I'm wanting to go about an inch deep at the slab edge, so the slope will be about 1" in 7 or 8" setback. I figure to rough away a lot of the material first with an electric hammer and a 3" wide bit. I tried cutting grooves, but I think that adds a lot of time & dust, but doesn't speed up the chipping process all that much. Will a concrete grinder, the kind that looks like a floor buffer, be difficult to control on the roughed slope area? thanks, bill
