I have a smaller 4in Makita angle grinder that I've used for years. And while it's mostly gotten the job done, it's become increasingly more difficult to find all of the 4in wheels and brushes that are available for the slightly larger 4-1/2 in grinders. Finally I decided to buy the Dewalt Angle Grinder Tool, 4-1/2-Inch, 11-Amp (DWE402K). This thing is a beast! Because this thing is such a powerful little machine (11 amps at 11,000 rpm), I strongly urge anyone buying this angle grinder to read all of the instructions, including ALL of the stuff about safety. Seriously - this is not a toy. This is a high-powered machine designed to do some really tough work. When turned on, it will almost jump out of your hands if you're not expecting the torque this thing has. I've come to buy numerous different wheels and brushes and this has been a pure joy to use. It is such a well-designed machine. The DWE402K comes with the basic DWE402 grinder, but includes a hard plastic case which I really like. While my new Dewalt grinder hasn't been in its case since I bought it, I like having cases for all my shop tools. When finished with a project and I'm cleaning up my shop, I like to clean up all of my tools and put them away in their respective cases together with any special tools or attachments. The dewalt comes with an allen wrench which I've never needed (stays in the case). And (sadly) there's not much spare room in the case for extra wheels or brushes. As for the grinder itself - I really like it for its design and ability to do real work. On some grinders, the guard is more of a pain because it's always in the way and can't be easily adjusted. So it's taken off and never put back on. That's shameful. Always use your guard, it's there to protect you. The guard on the Dewalt is genius. This guard is designed the way all guards should be. It can be easily rotated 360 degrees to any direction (read the instructions so you understand exactly how this works - and never try to adjust the guard without unplugging the grinder first) and the guard can be completely removed if ever needed. The 5/8in spindle is perfectly designed for quick changing wheels and brushes. The spin-on and off feature makes this a truly tool-less grinder. No special tools are needed to remove and replace wheels and brushes. Just twist them off an on with your hand. Again - unplug the grinder first - right?! The grinder also comes with a pair of 5/8in-to-7/8in "arbor" or a flat-washer-looking-thing for compressing wheels that don't spin-on to the spindle using threads, but rather have a larger clearance-hole, non-threaded diameter hole for mounting. It's a great system that requires no tools. The on-off control for the grinder is a simple paddle wheel with a built-in safety switch ... it's a breeze to use. Very comfortable. There's also an over-ride lock so you don't have to continuously hold down the paddle switch when working on large areas at a time. The power cord is tough but it's only 6ft long which in my mind seems a little short. My personal preference would be an 8ft or 10ft power cord. The only other improvement would be some sort of easy sky-hook to hang the grinder on the side of a bench or table. Bottom line, this Dewalt DWE402K Angle Grinder is the bomb! If you have serious work that needs to be done - this is the defacto standard in angle grinders. Seriously, this is one powerful and potentially dangerous beast of a tool in the wrong hands. For me - this is exactly what I was looking for! Be careful out there!

Quieter and more powerful than the previous model (which I still have and that has hundreds? thousands? of hours on over the last seven years), I *really* like the DWE402K. Admittedly, I take off the safety shield (bad consumer), but for most applications the adjustable feature of it would seem to work well. The ability to lock the tool in an 'on' position can save some hand fatigue over long grinding sessions and the long cord is convenient. The carrying case seems the same as years prior. A little more storage space for other discs would be nice, but it does its job. If you're used to Dewalt's older "wrench" type wheel fastening system, the switch to an Allen wrench takes a little getting used to. Personally, I find that the Allen wrench is a bit more finicky to align and use, but since the old two-prong wrench works fine I don't find it an inconvenience. This model seems a little heavier than the previous generation, but it makes up for it with more power and less roar. The removable handgrip I'm still a bit on the fence about. I liked the older soft/rubberized grip, but the one that comes with the DWE402K is a hard plastic. On the plus side, the hard plastic doesn't get torn up like the soft rubber does. The smoother operation also seems to produce less vibration, so the harder plastic may be a better deal in the long run from a durability standpoint. (Worst case, Amazon sells the original soft-grip handles as a replacement part and they fit on this new model just fine in case you prefer the softer handle over the hard one.) All in all, I don't have much to fault and by every important measure this is a worthy successor to Dewalt's prior model. I suspect it will run without incident for years to come.

Awesome little grinder that tackles the big jobs with ease. It works better than expected with power to spare.

Bought this to replace my old Harbor Freight grinder when it decided to start bleeding gear grease out the air vents. Figured it was time to spend some money on one of my most used tools rather than just replacing with another cheap one. After about 20 hrs on this tool here are my thoughts. - Its a good grinder, powerful and doesn't bog down even when applying more pressure than you should be. - Its fairly large but after getting used to it, especially with the side handle and trigger lock, it's pretty easy to get used to. - The guard angle is easily adjustable which is a huge time saver coming from one that used a lock nut. - The trigger is definitely not as easy to lock on/keep locked on as the straight up on off slider switch on the old grinder but it is vastly safer, and additionally, its nice to have the trigger for easy bursts of speed since this grinder has one speed only. - I recommend going for the kit with the box, its well made box and houses the grinder, handle and has some space for a few disks and wheels. Overall I would recommend it but will also be getting the milwaukee soon so I will update this review with a comparison once I do.

This is a very decent product I love the fact that it has a screw in handle and a safety guard that I can take off easily and use it at work regularly I work construction.

High powered angle grinder. Has my favorite type of switch on it as it's easier to activate and hold in the same position. Tooless adjustable guard is easy to use. Like having the case come with it. Could use a little longer cord but it's a minor thing.

Have used the grinder a couple of times. Great power and quality materials. Value for the money is ok.

Value for the money was fantastic!! Thank you. Use everyday almost to cut 1/4" thick steel. No problems at all, the paddle switch is easy to control. Locking mechanism on paddle switch is great and ideal for most of my applications. Weight is a heavier compared to Bauer, or Hercules of course, but way more durable than both of those too. Comes with thicker cord as well, the thicker rubberized coating is just great.
