Dewalt DW840K Angle Grinder



The Dewalt DW 840K 7-inch Angle Grinder with bag and wheels got an average rating of 4.7 on Amazon out of a full six reviews, that’s 4 real buyers rating it a full five stars and only two rating it 4. Later on in this review we will look at why two out of six reviewers failed to give it a perfect five. But first let’s start off with something good.

Priced at a little over $100, this yellow plated angle grinder has an 8000 RPM motor, together with a 13.0 amp AC/DC which gives it the incredible power and high speed for any 7 inch grinding applications. With its high power to weight ratio, the DeWalt DW840K has found the perfect balance to reduce user fatigue and allows full much greater efficiency.




When manufacturing this tool, the development team at Dewalt made sure to increase the productivity of any industry professionals using this particular grinder by adding a keyless adjustable guard, which provides the user the ability to easily make adjustments.

The motor is also protected by a sealed bowl and roller bearings which generally extends the motor life, so you can be assured that this tool will be a long-lasting companion. With the firm, rear handle design, the Dewalt DW 840K 7 inch angle grinder is easier to control than most other grinders on the market and much more comfortable to work with. The external brush caps also allows for easy servicing, should you need to do so somewhere along the line.

Now that you have all the specs and fancy details out of the way, let’s look at what the other buyers of this product say…

Dewalt has been known to make some of the best DIY power tools in the industry over the years, and it surely doesn’t look like they’re going to stop any time soon. One user in particular stated that he also has the DeWalt D28402K small angle grinder kit, as well as the Milwaukee 6088-30 large angle grinder.

Known as “Max Power” on Amazon, this reviewer has stated “all three are five-star grinders, built to last and easily serviceable, metal gear casing, roller bearing construction, with screw off brush caps, and screwed on side handle.” He also stated: “cutting rebar and galvanized pipe with it is a breeze. It’s easy to get into tight spaces and control, -also the attachments for it are the cheapest.”

Between the smaller Dewalt angle grinder and the larger Milwaukee one, this industry specialist says: “this 13 amp Dewalt is a really nice mix between those two extremes.” So if you’re looking for the perfect angle grinder for household and small business task, then this one might be perfect for you. The only complaints from the users that gave it four out of five stars, is that “when the trigger is released and it is still spinning to a stop, sounds a bit noisy still.” Not that I would say 3 to 5 seconds’ noisiness when switching off the tool is too much to complain about, but to each his own!

All in all, the Dewalt DW840K seems like a pretty solid 7 inch angle grinder,-and also comes with a bag and wheels to allow for easier transportation.
