Review: very good diamond blade - This DEWALT diamond blade worked perfectly for my masonry project—smooth, clean cuts with no chipping, and it handled brick and pavers with no problem at all. It fit my grinder easily, stayed steady, and is holding up really well after multiple uses. Excellent quality for the price!
Review: Quality at a fair price. - Seems to be a decent blade, my first time using one. I found a giant lump of concrete in my lawn that is too large to carry, so this is being used to chip away at it slowly. You will probably need a strong battery/grinder as this tends to put more load than typical grinding tasks. I found this blade cheaper than from the hardware store. This blade operates smoothly, no more vibration than other discs. I have not noticed any dulling after several runs with a 5ah battery on my grinder. If you need to cut masonry/concrete and aren't sure exactly what to buy, start with this disc.

## Questions & Answers

**Q: Will this blade cut cast iron pipe?**
A: it will cut steel but it will wear it out very fast . i am a mason and cut rebar with these blades all the time . not sure about cast iron but softer steel they will cut although they are not intended to be used for that

**Q: Will this fit a DeWalt model D28402W?**
A: Yes, you can use this with the DW402 but you need to get the DW4706 Backing Flange. Amazon sells it for $2.99 as an add-on item. You need this flange for any type 1 cutting wheel used on a type 72 grinder (cupped surface disks). BTW, the arbor is 7/8" for disks that don't screw on, and 5/8" threads for those that do screw on. Hence you need cutting disks, like this one, with a 7/8" arbor. This applies for all grinders, not just Dewalt.

**Q: Will this fit the cordless dewalt 4 1/2 dcg412?  thanks**
A: It will fit any 4 1/2". Cord or no cord is irrelevant.

**Q: Will this grid carbide bits?**
A: This a Diamond Saw Blade, its used to cut tile, brick, concrete, Masonry type work. Not intended for cutting metal. I cut tile and concrete with mine.

### ⭐⭐⭐⭐⭐ Excellent Masonry Blade for Clean Cuts
*by D***D on July 17, 2024*

As a DIY enthusiast, I often tackle various masonry projects, and the DEWALT Diamond Blade has become my go-to tool for these tasks. It delivers precise, clean cuts every time, making my work much easier and more efficient. What I particularly like about this blade is its durability and performance. It cuts through masonry like a hot knife through butter, whether I'm working with bricks, tiles, or concrete. The continuous rim design helps in achieving smooth edges without chipping, which is crucial for a professional finish. The blade's compatibility with my angle grinder is seamless, and it remains stable during operation, reducing vibrations significantly. This stability not only enhances control but also reduces fatigue during extended use. It's also great for dry cutting, which means I don't have to deal with the mess of water-cooled systems. However, it's important to note that the blade can generate a fair amount of dust. I always make sure to use it in a well-ventilated area or with proper dust collection measures. Additionally, wearing safety gear, especially goggles and a mask, is a must to protect from the fine particles. In essence, the DEWALT Diamond Blade for Masonry is a reliable and efficient tool that has greatly improved my masonry projects. Its durability and precision make it a worthwhile investment for any DIYer or professional looking for clean and effortless cuts.
