With the increased popularity of concrete being used inside and outside the home, Alpha Professional Tools® has developed the Alpha® Crack Chasing Wheel for repairing cracks. This V-cut wheel style produces a 1/2 inch wide, 70-degree, V-shaped groove for re-caulking and re-filling. The 4” wheel fits on the Alpha® Ecocutter, thus creating a portable, dust-free operation eliminating unnecessary cleanup.
