DEWALT Diamond Blade, Tuck Point, 4-1/2-Inch x 1/4-Inch (DW4740)

Speed: A+ Control: A+ Ease of use: A+ Speed of mortor removal: A+ Durability: A+ I used this to remove all the mortor from my brick steps, and it went fast. You can be precise and go slow, or fast and, and an entire joint in one pass. Great for amateur or professional. Even if the original joint was too wide or too narrow, you can make perfect lines with this blade. If you need to repair mortor, this is the best blade I've used. I used an oscillating tool to get into tight spaces, but that takes forever, regardless of the tool. I thought mortor removal would be the hardest part of the job, but it was the easiest with this blade. Dust control: well, depending on the side of the job, this is an issue. I was doing over 13 steps and two platforms with vertical, horizontal, edge, and corner areas. Thus a dust control guard with vacuum/ dust collector attachment was not possible to reach small spaces. However if you are doing a simple patio, or have mostly horizontal or long vertical surfaces, maybe it's worth considering. I was working by myself and using the angle grinder alone-without the dust collector-it got taxing on my hands and forearms. I can't imagine how harder it would be to move it around if it had a dust collector and hose attached. Simply put, move your cars, wear glasses and ear protection, and keep an electric blower or air compressor hose handy to blow the work area. Or a hose with water. Also, there was so much dust I needed to wear a respirator (painting mask). An N92 or dust mask will be insufficient, as I tried this and clogged my nose and mouth with dust. Cover your ears too, or they will fill with dust. It makes so much dust it looks like it snowed in a 50ft radius around my work area. I did it in Florida heat, and still covered every inch of my body, especially my head, using a bandanna so my hair was not covered in mortor particles and fine dust. I also wore a respirator even though I was outside. Further to note: my angle grinder, despite cleaning it each day with compressed air clogged the switch and made the tool inoperable from dust. However since my DeWalt is a professional model I could rebuild the switch easily, however it did take away from work time. Either way, you must clean your tools with this type of work or the dust will kill them, just like any brand. Dust = tool death. Any professional will tell you this. Simply taking apart and cleaning the switch did not work. Using wet Lube or grease did not work. I used Dry Lube and it not only worked, but after the job I disassembled the switch to inspect it, and the switch didn't collect fine dust and worked perfectly. See video. For doing steps I highly recommend an angle grinder with a 3 point handle attachment, which is hard to find these days (maybe for legal reasons). I recommend this because the tool will be perpendicular to the tuck groove you are removing mortor from. (pictures will demonstrate). I'm sure any angle grinder will work fine, but I can almost gutantee you will kill it if you don't get a good one for this job. 120v corded should be the way to go due to the durability, power, and time you will operate the angle grinder. You will have a heavier tool if it is battery powered, and I'd say you need at least 4 batteries constantly charging, somewhere completely away from the dust if you go that route, if you don't want downtime. Overall these types of blades are very expensive, and this one is a solid one piece diamond blade, that is not too thin, so you only have to make one pass to clear the joint. Other brands are too thin, and you have to make several passes. The new style from DeWalt also is different, and not a solid one piece design. Also, since this blade is so thick you can easily shape brick/ rock etc. As you work without changing blades. DeWalt makes a new updated style tuck point blade for removing mortor, but I see no need for spending that type of cash when this one is sturdy, doesn't bend on a bad angle, and works flawlessly. Any claim of removing mortor faster with the new style VS. this old style, well may not be noticed by a do-it-yourselfer, or even a professional, because this blade works so fast, the only thing slowing it down is the operator. Also, any faster and you probably won't be able to see what you are doing without a dust collector. Please note: if you are buying a tool specifically for steps, a larger blade and tool may make your life easier, as it could then reach the riser joints easier due to the larger blade. Durability and Wear: A+ this blade was punished for days on end, and it barely shows any wear.

Excellent blade! This blade is superb for tuck point work. it works very well in my Makita grinder and my Boschgrinder. If you have brick motar maintance to do this is the blade you need to make your work much much easier and to do a neat and professional job. Highly recommend this blade.

Worked great re-pointing my front steps. Definitely wear eye protection and a dust mask. After about 50 bricks I can see zero signs of wear on the disc's cutting edges.

Amazon review 10/3/2020 for the DEWALT Diamond Blade, Tuck Point, 4-1/2-Inch x 1/4-Inch (DW4740). This blade does a good job of removing mortar between bricks and concrete blocks. It's trickier to use on the short verticals w/o damaging the next brick/block. One must still do manual chiseling at those points. This tool is better than using a chisel and hammer overall. There's less damage to the brick or concrete blocks. In fact, I find it near to impossible to chisel out some mortar. Be sure to fully protect yourself while using this product. It generates a very large cloud of highly toxic silica-laden dust. At the very minimum, equip yourself with a N95 mask, non-vented safety goggles, and an impact face shield (not a thin one used for chemical splash avoidance). Long sleeve heavy work shirt, long pants, shoes/socks with no exposed skin to avoid flying chips. Pro's will be using full face ventilators and that is something to consider as well. Keep your body out of the line of the spinning disc, and use the appropriate safety shield on the tool. Overall, a recommended product.

This is a great blade. I had several mortar joints in my basement wall that had deteriorated (I have a very old home) and were in need of repair. This blade made very short work of these old joints. Everything was cleaned out and new hydraulic cement installed, drylock applied. These walls are dry as a bone and I owe it all to this GREAT blade. Very easy to use. ALERT: THIS BLADE WORKS GREAT, BUT BE VERY PREPARED FOR THE DUST IT GENERATES. I'M TALKING ABOUT A CRAZY AMOUNT OF DUST!!! HAVE A PLAN IN PLACE TO TRY TO MINIMIZE DUST SPREADING THROUGHOUT THE ENTIRE HOUSE IF WORKING INSIDE!!!!!!!!

The blades has cut a total of 1500' at 1" depth and still going strong. Just love the durability. It was a great purchase and delivery was timely.

Works great. Chews through mortar joints like the proverbial hot knife. I can't compare this blade to other diamond wheels, as this is the only one I've ever used, and I've only used it for a couple weeks, so I can't confirm the marketing copy about "350x" the life of conventional abrasives. Obviously a diamond wheel is going to outlast a carborundum wheel—by exactly how much I can't say. (Hopefully someone else has been able to address that here, to provide a more complete review. I ultimately chose this blade because of its Prime availability and competitive price vs. other similar diamond blades.) But even if the diamond blade, at its higher price, does not outlast the same dollar-value-amount of conventional wheels it still offers the advantage of wasting the mortar joint much more rapidly. And that time is money too.

I used to use cheap abrasive grinding wheels to work on mortar. They are slow and wore down rapidly. This grinding wheel claims it will outlast 300 regular wheels and I believe it. I'm a homeowner, not a professional mason. Comparing this diamond wheel to abrasive wheels is like comparing a bic lighter to a flamethrower. It cuts rapidly, easily and is incredibly durable. If you have any significant amount of mortar to grind out, get this wheel. It makes the job go way faster. Not only does it cut faster, you don't have to keep replacing grinding wheels because it does not wear out so fast. I suspect I'll never need to replace it unless somehow I break it. Highly recommended!

Excellent tool, when compare to a chisel and hammer, it is quite easy to use and saves a lot of time

These blades are great for tuck pointing, and are almost 3x the cost at big box stores!

Well made

Tough as nails repointed chimney blade like new

Perfecto
