DEWALTAngle Grinder Tool Kit with Bag and Cutting Wheels, 7-Inch, 13-Amp (DW840K), full size

What a beast. I use it with a kutzall 7" wheel. As soon as you pull the trigger it jerks to full speed. It removes hardwood like i never seen before. Only thing is, It could have done well with a motor break.I definitely do not recommend this for the beginner. It is a big very powerful tool.Approach with Caution !!!!!

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.

i HAD TO GET THE 94 DOLLAR DISK BUT IT GROUND CONCRETE LEVEL AND SMOUTH IN SECONDS

Blows the 4 1/2 grinders away. Installed a cement cutting blade and goest thru concrete with ease.

Only used it once for something we didnt plain on. Will let you know when we use it on concrete stairs to redo them but I am sure this will do the job with no problem. Thanks

Great grinder. Very powerful compared to my old Craftsman.

hard to beat in terms of quality and reliability. I don't need to use this tool often, but when I do, I'm happy I bought a quality tool that does the job with efficiency and ease.

Worth the price.

I bought this to replace my 25 years old 4" Dewalt angle grinder. Best money I have spent, sorry I got it on sale here weeks ago. I bought 2 7" diamond blades for concrete and stone, and finished up my landscaping rock walls I was redoing roughly 200 linear feet by 18 " high. I was worried about using a 7" over my old 4" but this unit is well balanced and easy to control. Its a little louder then my old 4" but that makes sense, but I always use ear protection and a concrete rated mask. I would buy this again if I needed too, thank-you Dewalt.

Very well built tool Good for heavy jobs

soooo glade nice Grinder thant you
