Crack Chaser Blade for Concrete, Asphalt Repair - 4 ...
This grinder wheel needed no pressure to open the cracks to a tapered width of about 1/4" and a depth of about 3/8". You need eye and breathing protection as grinding creates a lot of dust. I could see no wear to the grinding wheel after tracing over 100' of concrete cracks. Just be careful with the angle grinder.
