Pearl Abrasive PVV904M 4 x 5/8-11 Threaded Crack-Chaser Blade

Pearl Abrasive PVV904M 4 x 5/8-11 Threaded Crack-Chaser Blade. The Crack-Chaser™ has been engineered to quickly sink into cracks and crevices. Simply place the wheel on the crack and let the diamonds do the work. The special design enables the Crack-Chaser™ to produce a 1/2” wide 70° V-shaped groove. This has proven to be the most effective configuration for re-caulking and re-filling.
