They are either too thick or too small to remove grout from shower tiles. The rounded blade is too small in diameter and does not protrude far enough from the vibrating tool (see photo) to penetrate crevices or corners. Another photo shows that the blade purchased from Home Depot is much larger than the similar XXGO. Also, the side view photo shows that the XXGO blade is much thicker than the diamond tipped blade (also purchased from Revain). My tile gap was smaller than the XXGO blade and so I couldn't remove the grout without damaging the tile. By the way, the diamond blade easily coped with cleaning the solution.
