Review on 5/8-11 Arbor Crack Chaser Blade For Cured Concrete, Asphalt Repair Or Joint Widening (0.5" Width) by Girish Underwood

This tool is amazing. It grinds out cracks in cement slabs very quickly and efficiently. Needless to say, grinding cement is a VERY dusty business, so take appropriate precautions, especially if you're grinding indoors. We put up plastic sheeting around the entire area we were grinding, from ceiling to floor, hand-held a shop-vac with a hepa filter behind the grinding wheel, and wore a high quality 3M P-95 mask & face shield. The result was a nice v-shaped groove that made it easy to fill and seal the cracks with a high quality cement crack caulk.
