A carbide tipped masonry bit is a second choice. • Place a piece of tape over the area to be drilled to help prevent chipping. • Drill a pilot hole for the porcelain cutter. Use the pilot drill supplied with the kit or a carbide tipped drill. • When drilling the 1/2” hole, drill slowly and carefully; the porcelain chips easily. • After drilling, clean the area well. Iron fillings, if left in place, can cause rust stains. Drilling a Counter top NOTE: The counter top must be less than 2¼" thick.
