Review on 🔪 Durable DEWALT Diamond Blade for Dry Cutting Masonry - 4-1/2-Inch Continuous Rim Blade (DW4725) by Jeff Kern

Excellent quality for the price. I used this to cut out the incredibly old and therefore hard concrete around the pool so as not to dislodge the diving boards. I cut a few 3/4 inch thick slices and then hollowed them out with a rock chisel. My previous diamond blade wore out 50 percent faster than this one, I think. You can't go wrong with this, especially for the price. I haven't used them on tile but I suspect they would work well on tile too given the cleanliness they cut through quartz gravel. I ran them dry on a fairly cheap ($11) angle grinder. I will say that they produced more dust than the previous knife I used, but that may have more to do with the cheap coffee grinder I bought after my much more expensive coffee grinder blocked me. I plan to try the same blades on an old cast iron pipe in my house. I will update with information on how they work.
