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

This blade is 1/8 inch thick and works incredibly well on very hard grout. I've tried both expensive ($34) and cheap ($4) blades. carbide and diamond. The project I'm working on has a very hard grout. On earlier blades, the abrasive bond will wear down to bare metal after 10-30 minutes of use. This blade can last hours before I have to replace it. It also wears away material much faster, making work faster.
