Review on 🔧 Efficient XXGO 4 Pcs Oscillating Multi Tool Diamond Segment Swing Grit Grout Blades XG4001S: Enhance Precision and Durability! by Ben Alvarez

These blades looked good because of the thickness of the diamonds on the cutting edge. I was stupid to think the diamonds were as big as they looked. At the price of these abrasives this would be impossible. The abrasive coating covers the side of the blade by about 3/8 inch, but the actual cutting edge wears away after less than five square inches of mortar cutting. The quality is good for the price but you can't buy much. Diamonds for three dollars.
