Ideal for cutting or scoring through a coating or substrate to isolate a specific diameter test area for adhesion testing.
Test area isolation (if required)
Use a 14, 20, or 50 mm hole saw to cut or score through coatings around the edges of a dolly (pull stub) to isolate a certain diameter test region and remove excess adhesive.
NOTE: For coatings with strong lateral bonding, it is suggested that you cut entirely through the coating to the substrate.
Testing concrete repairs and overlays in line with ASTM C1583.
Using the 50 mm diamond-impregnated hole saw, drill a circular incision perpendicular to the surface to a depth of at least 10 mm (0.5 inches).
