4 Inch Diamond Blade for Angle Grinder — Diamond Cutting Wheel for Cutting Stone, Marble, Granite, Brick, Masonry, Paving Flag, Concrete — Diamond Saw Blades Segment Height 0.394” (10 mm) — GRAFF

Based on the Q&A and customer reviews, the diamond blade is well-suited for cutting through concrete, block and caps for retaining walls, and paver stones, but may not be suitable for cutting precise or smooth cuts. Customers noted that the blade's effectiveness depends on the saw being used and if the blade hole size fits the saw. One customer reported that the blade became dull after only two cuts through soft limestone. Another customer mentioned that this blade is a "poorer quality" option compared to another brand, while one customer seemed to have difficulty cutting porcelain tile with this blade. Overall, customers who used the blade for its intended purpose found it to be effective and worth purchasing again.
