Review on 🔪 DEWALT DWA4220: Efficient Fast Cutting Oscillating Tool Blade for Grout Removal by Tim Blandin

Today this blade easily removed 1/4 inch grout lines on 54ft of floor tile. The tool used was a Dremel Multimax at speed 6. The old grout I removed was about 1/2 inch deep between the tiles. I made about 4 passes to get to the grout layer between the tiles and vacuumed as I worked. I was able to remove grout from all sides of 18" floor tiles in about 5 minutes each. It was about twice as fast as other gold-colored solid carbide blades I've used. and it happened. As mentioned, this blade consists of two parts. Given my concern based on negative reviews that the rivets on this item would fall out at the junction of two pieces, I decided to have a reliable but slower gold-colored carbide cutting blade on hand.
