This grinder is a beast ! It has exceptional power. It's easy to change disks , seems to be well balanced and doesn't bog down. I've been using mine to grind rust off the body of a commercial truck - this grinder removes material very quickly. It comes with a nice bag and a long cord. I have several 4" angle grinders and am astonished at how much more work I can get accomplished due to the larger size of the wheels. I am very pleased with the grinder , wheels and bag. The tool seems to be very well made and durable. I have no complaints about this tool.

In addition to this 13amp dewalt, I have these angle grinders: DEWALT D28402K 4-1/2-Inch Small-Angle Grinder Kit Milwaukee 6088-30 7-Inch/9-Inch Large Angle Grinder with Lock-On All three are 5 star grinders, built to last and easily serviceable, metal gear casing, roller bearing construction, with screw off brush caps, and screw on side-handle. The 4-1/2 10amp dewalt is really nice to do tiny cuts in steel. Cutting rebar and galvanized pipe with it is a breeze. It's easy to take out because its very compact, you don't have to worry about it getting enough power on a 100' of cord, and it's easy to get into tight spaces and control. Also attachments for it are the cheapest. The 15amp milwaukee has the best shield guard. It is permanently affixed to the grinder with torx screws, but you can rotate it by depressing a clip, which is really nice. I use this one for grinding down concrete for sidewalk and foundation repairs. I've also used it to cut through 6" thick cast iron pipe to remove an old commercial boiler system. It is the largest and heaviest, and could cut a car in half. You can go deeper with 9" obviously, and I think the milwaukee must be geared down a bit to handle the extra circumference. This 13amp dewalt is a really nice mix between those two extremes. It is the more well rounded of the two tools and could probably do either tools job. If I kept only one this would be it. It's small enough that you could finagle it under a kitchen sink, but that is probably the smallest conceivable space you could grind in. And at the same time it can still grind concrete, cut through thick metal, and spin the heck out of a wire cup brush or sanding pad. The only thing is the shield guard is a bit chintzy, and is basically a compression fitting that you screw tight with a single screw, and to move it you have to break out your screwdriver. I keep a big screwdriver in the bag for that purpose. The bag it comes with is decent, thick reinforced nylon. The wheels it comes with are great, I just absolutely melted through steel bars like they were butter, molten sparks were flying, the bar was glowing red, and 2 seconds later I was done, so it was like sex. It feels like it has more torque than my milwaukee. My milwaukee is quite a bit older though, made in the US and I don't know it's history so it might not be a fair comparison. There are tons of attachments for angle grinders.. wood stock removal sanders, metal buffers, metal cutters, metal grinders, metal sanders, concrete grinders, undercut blades, and even chainsaw blades (called lancelot). I think cutting metal and grinding concrete is what they are built for. Be careful to match the RPM of the attachment to the tool, because some attachments aren't built for over 6,000 RPS, and its best to play it safe I think. Also using a saw blade on an angle grinder can produce dangerous kickback, especially on a powerful angle grinder like this one, even though they make attachments for it, I wouldn't recommend it. Dewalts are made in mexico, their corporate headquarters are in Baltimore Maryland.

You need a PROPER dust hood-especially if cutting lead paint with a Dewalt diamond cup to remove lead paint. I believe silica-in cement-is a carcinogen too. Do not take a chance as this creates a huge dust storm. I used a 3M NIOSH mask and goggles- both a must, to grind old loose paint off a basement wall for waterproofing and painting. Incredibly difficult job with great results-short of my soreness. I used this 7"Dewalt grinder and the DustBuddie hood- bad combination, really bad. Diamond wheel recessed in the hood too far and the diamond tool ate the brush on the hood. Huge mess and the hood failed. I contacted Dustless Technologies and they sent a new dust buddie and a shaft-extender- also a bad plan. Shaft extender was eccentric and 3weeks later my shoulders and hands still hurt. No kidding, still have a blister. The hood barely worked, the bearings in the grinder are probably ruined and I nearly choked to death toward the end as the second Dust Buddie rattled to pieces. It was a job I HAD to do bu a certain date, so fought through it. Diamond tool and grinder were great-dust Buddie did not. Do not try this before verifying an un-modified grinder shaft fits your vacuum hood.

Works well, very powerful
Reviewed in the United States on December 9, 2024 by L. Bishop
The DEWALT Angle Grinder Tool Kit (DW840K) is a powerful and reliable tool that’s perfect for heavy-duty grinding and cutting tasks. The 13-amp motor delivers plenty of power, and the 7-inch wheel size makes it great for larger projects. The included cutting wheels and carrying bag are a nice bonus, making it easy to transport and store. My only reason for giving four stars instead of five is that the grinder feels a bit heavy during extended use, which can cause some fatigue. Additionally, the power switch could be positioned better for improved comfort. Overall, it’s a high-quality tool that gets the job done efficiently. I’d recommend it to anyone needing a dependable angle grinder with solid performance.

As I needed to cut through 3-inch asphalt to repair my driveway, I decided to upgrade to a larger angle grinder. The 7-inch version from DeWalt worked well, helping me to cut through nearly 100 feet of asphalt with no problem. Interestingly, the manual states that the tool should not be used for this type of work because of the lack of the correct guard, but it worked fine. I used a face shield to be safe. The button which needs to be depressed to start the tool is a bit awkward for lefthanders, but that is my life.

This is a very nice grinder, well-made and designed. I considered a couple other brands when shopping for one, and narrowed my choice down to this one and one other. The price of this one pushed it to the front. It was about $70 less expensive than my runner-up. I've used it a number of times and can recommend it. The included bag is good for hauling hand tools to small jobs, drop in some wrenches and etc. and set it on the floor of the pickup, easy. But the grinder works quite well and looks as if it'll last me for many years. I have used it for grinding concrete and heavy-gauge steel and for cutting some steel fence posts, works great.

Calidad excelente como se espera en DeWalt. Es una pulidora un poco mas pequeña que la habítual lo que la hace mas maniobrable. El switch me parece mucho mejor que el convensional ya que me parece que la hace mas segura de usar. incluye accesorio de sporte, llave para cambio de disco y un disco para pulir
