    The power is immediately noticeable. I intend to use these for knotted wire cup brush use where the power is really needed. You don’t need the power for a cutting disk as any less powerful unit will easily do. The power also comes in handy when flap discs start to wear out and you have to press harder to get the last bit of use out of that item.These are also very smooth and low in vibration. The paddle switch is easy to use and since you have to hold the tool anyway, is the only way a dangerous tool like any angle grinder should be used. I learned that lesson the hard way when I had an angle grinder with a normal on/off switch get wrenched out of my hands and it proceeded to climb up my chest and flew over my shoulder and continued gyrating on the ground till I unplugged its power cord. I no longer own an angle grinder with an on/off switch and I own 11 angle grinders.

    Absolutely best Dewalt 4.5″ grinder compared to other Dewalt grinders. I have 4 Dewalt grinders. All 4 are great tools, but this one is my favorite.Updated to say; I just ordered 3 more of these grinders. I LOVE the one touch guard!!!! You just bump it against the welding table to rotate it to any position you need….I’m quickly replacing all my grinders with these Dewalts….I like to keep about 10 grinders plugged in with different wheels and discs ready to grab, and these paddle switch high amp Dewalts have proven the best bang for the buck yet over all the others.Updated again to say I just ordered another one of these as a gift to a new neighbor. He is notchin his truck frame to slam it on the ground….I now have 10 is these grinders in my welding shop. They are excellent.

    Works fine. I prefer a trigger style grinder with the “tail” handle, but the budget didn’t allow it. The paddle is ok, the safety is kind of annoying.Also, to clear things up, in the q & a about the arbor size. The arbor is 5/8″, with 5/8×11 threads, but the locking flange that holds grinding and cutting discs has a 7/8 shoulder. So any non-threaded accessories should have a 7/8 hole in order to have them sit properly on the flanges. Photo shows .875 (7/8) inches flange shoulder on the micrometer

    Although I do the majority of my angle grinder work with a 7″ grinder, I also do a fair amount of work with a “small” angle grinder. I purchased this as a replacement for a Milwaukee 4 1/2″ angle grinder. This grinder has noticeably more power, is more comfortable to use, and one feature I really like is the use of a large allen wrench to tighten/loosen the wheel nut. Most other grinders require you use a spanner wrench AND a shaft wrench. This grinder has a spindle lock button, and a single allen wrench (included) to tighten/loosen the wheel nut. It’s a very simple and slick solution to the hassle of having to use two different wrenches to change wheels/discs. About the only CON I can see so far is that there is a safety “lock” on the paddle on/off switch (if you use an angle grinder much, don’t ever buy one with a slide switch…they either wear out quickly, or jam up from grinding debris after a short time)….. which is awkward/difficult to manipulate when wearing gloves, and tends to “stick” when it gets dirty from grinding swarf/dust. I will likely remove it…. it’s held in by a simple “roll pin”. This grinder carries a 3 year warranty….. we’ll see how that plays out….. I use grinders everyday, and likely put more work on one in a year then most people would in a lifetime.

    Lighter weight and better balance in comparison to others. Paddle switch does not pinch fingers and the safety is easier to actuate yet still safe. Most of the time a tool is not needed to remove a disc, but if the disc balks, it will cinch and the tool is required. Body of grinder is large enough to make a one handed grip a bit tiring but is on the smaller side in comparison to others. If I used this all day with one hand, I would choose a model with soft start. 11 amps gives a lot of torque. I’m a fan of the red brand but in this case I went yellow and black.

    Great Product – No issues so far – Used to sharpen my lawnmower bladesGrinder came with case and wrenchThe picture I have attached shows the unthreaded backing flange and the threaded locking flange which come with the angle grinder. Instructions advised to take both of these off for the grinding disks that I bought (Dewalt DW4523)(The 2 grinding disks pictured DO NOT come with the kit)No other adapters comes with this angle grinder.

    Mind bending quality and power. I bought this because we had a concrete sidewalk installed and the contractor got concrete into the window frame of a basement window. The only solution I could think of was to cut a straight line where the window used to be. I thought I’d be at it four hours, but this tool cut a dead straight line through the concrete in about 15 minutes. Bought an extra blade thinking I’d need it, but the one blade did the job without showing any sign of wear. Very impressed. I have other DeWalt tools and their quality is excellent, but this really exceeded my expectations especially based on the price.

    Best grinder ever! I used an older model similar to this one and used it for 10 years, the bearings were obviously shot (later in its life) but it still worked! In my opinion dewalt is still high quality even in this day of mostly cheap goods and higher profits. I expect this grinder to last me 20 years or more. TIP: find some way to attach the mandrel nut to the cord so you don’t misplace it and you always have it handy. Small downside it doesn’t have variable speed, oh well…

    Used with a diamond blade to cut a bunch of concrete pavers, had zero problems. The motor is more than powerful enough to cut concrete with the right blade quickly and without bogging down at all even when you’re probably putting more pressure into the cut than you ought to out of impatience. This model is made in the USA, which is a plus.It’s important to note that the guard it comes with is for Type 27 grinding wheels, you’re supposed to get a Type 1 guard for cutting wheels. The guard it comes with doesn’t stop you from successfully using a cutting blade, it works, but it’s something to keep in mind – it’s always better to be as safe as you can.The housing and everything seems sturdy enough, it doesn’t feel cheap. It’s nice that the handle can be put on either side depending on how you want to approach the cut with it. The guard adjusts easily, you can modify it to either one touch or two touch – it comes preset as a two touch adjustment which I personally prefer. The paddle switch on the bottom is in a good location which makes engaging and disengaging the tool easy and the accidental trigger lockout that prevents you from accidentally depressing it when you’re just handling the tool works well and doesn’t get in your way at all when you intend to start it, virtually transparent in regular use.The case the kit I bought came with is pretty nice, it holds the tool and the power cord easily enough that you’re not cursing trying to cram everything back in after you’re done and there is enough room in there to store a stack of wheels with the grinder. There isn’t room in the case to put the tool away with a wheel installed on it, which might annoy some, but honestly you probably should never store a grinder with a blade installed anyway in case a kid gets their hands on it and decides to monkey around with it.

    Always been a Milwaukee guy. Wanted another grinder so I didn’t have to keep switching from a zip wheel to a grinding wheel. Saw the price of the Milwaukee and decided I would live with out. This grinder came up at a crazy low sale price so I thought I would give it a try. So far, I am impressed. The high rpm makes precise zip wheel cutting a challenge, so I have a stone on the dewalt. Removes material fast. Two complaints 1) the “safety” on the trigger was hard to operate and made use rather tedious. Notice the use of past tense. 2) noise – it is loud – just no load running it sounds like there isn’t any grease in the gear box. Opened it up to check. It was fine. Maybe as the gears wear in it will quiet down.

    Sin duda la mejor amoladora que he tenido en mis manos… Buen tamaño, manejo rápido para manipular la guarda, cambio rápido de los discos con la llave Allen, gran potencia de trabajo con menor esfuerzo físico…Es la primera que tengo con estuche o caja para su transporte… La recomiendo ampliamente y al vendedor también… Llego rápido aun con los días festivos, la pedí el 25 de diciembre y me llegó el 2 de enero.

    This is one powerful grinder!! Almost jumped out of my hands the first time I turned it on. This thing grinds through the toughest projects with ease. 11 amps of power make everything possible. Was really surprised at the quality and I think this grinder will last a long time

    Really a nice grinder for those heavy duty jobs but you better be paying attention because nothing will stall it. It’s going to kick or jump instead. If you do any continuous grinding jobs, it’s just too heavy to use for extended periods…

    Good price for an 11 amp grinder. So far, I’ve just used it for cutting some angle iron and grinding rust off steel plate. It did a great job on both. Others have complained about the paddle switch, but I had no problem with it and I have nothing to compare it with, since it’s my first grinder. I would say that the instructions could have been a little clearer but it didn’t take too long to figure out. I’d buy it again.
