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

Our 1951 driveway concrete slab had settled and cracked over the years and I purchased the 4.5-inch diameter/0.5-inch wide crack chaser wheel for my angle grinder. The crack chaser wheel worked very well in opening up the existing cracks prior to installation of a self-leveling polyurethane product. I utilized the crack chaser wheel on 75-lineal feet of cracks and it appears to have experienced little wear and tear. The wheel is well made and its integral nut for removal from grinder spindle is a great feature.
