DEWALT Concrete Surface Grinder Kit, 5-Inch (DWE46253)

I recently chiseled away an old ceramic floor from the early 80's (yes it was ugly..), what was left could be described as something similar to a relief map of the Himalayan mountains minus snowy peaks and Yeti tracks. The remaining concrete/thinset/ceramic/epoxy (yes someone cheated years ago on a patch job) proved to be stubborn to all but a 3lb sledge and hardened chisel. Having many DeWalt tools and being mostly pleased with their performance I chose to give this guy a try. Summary: The Good: 1. Ergonomics - Handle placement and controls are well though out. I set the speed and ran 2-3 sq feet to get a feel then went to town. 2. Grind-ability - Ample torque to handle even the highest peaks of the remaining flooring substrate. I experienced little to no kick-back when transitioning from smallest to largest of the pinnacles. The Neutral: 1. Dust Catcher - While very effective in minimizing dust from the flattening of the hills, the front of the dust guard opens fairly easily when bumping up against a corner or wall. Once I ran a few more yards along a wall I was able to get around this little nuance by making the closest pass from right to left ensuring the guard would stay in the closed position. Here a little stronger detente or slide lock in the plastic retention feature would be good. 2. Retention thumb screws for the handle - The female receptacle for the thumb screws needs to incorporate either a nylock type nut or a ratcheted base. I found after a few hours of grinding that the handle screws would loosen. Not a big deal as they have beefy caps that are easy to turn and torque down again. 3. This is not a daily use tool so it would be nice to see a hard case or tool bag for storage. The Needs Improvement: 1. Speed control for the brush-less motor - Maybe I am biased here because I have done a lot of development for brush-less motor controllers in the medical field, but I find the transitions between speeds to be "chunky". Having variable speeds is an A+ and in no way does the transition between speed settings affect overall performance, I would just like to see the steps have a smoother transition. In conclusion, this is another DeWalt tool that is a win. Value for capability is high. Build quality is high. I am impressed how well this thing chews through the slag that was left from the floor. Bonus points for having a side handle included so it can double as a grinder when the flooring work is done.

I have owned just about every kind of angle grinder made after 40+ years of hard work. When it comes to soothing out or prepping your concrete for tile or an overlay this is a great tool. The controls are laid out well, the weight is just right and its dust shielding feature works great. I connect mine to a Dustopper unit that collects the vast majority of the concrete dust before then going to my big Rigid shop vac. The perfect setup. I highly recommend this.

We had to waterproof basement. This grinder is woman friendly and/or beginner friendly. Speed adjust is on a click wheel and the on switch locks on. For safety, there is an instant shutoff brake. The dust housing works perfectly! The diamond wheel cuts beautifully. I recommend to add the DeWalt dust separator 6 gallon and the Craftsman 16 gallon shop vac. Run the bag and filter on the shop vac so in case the bag tears, the filter will keep clean. The dust cyclone traps 95-98% of the dust. The vac is the power source and insurance. These tools are contractor quality (just toss the bag that comes in vac and replace with Powertec bags [twice as thick])

Used to remove paint and texture from concrete patio to prepare for tiling. Worked great. Awesome tool!

Grinder worked great, dust collector is amazing. I went to use the grinder again a few months later and not even 5 minutes I get shocked and it turned off. With no breaker trip I turned it back on and that was followed by a nice spark and smoked out the motor. I sent the grinder for repair a month ago after I was sent to a local service center that was going out of business. After waiting a month I had to call them to see what’s going on. I’m told it’s un repairable and they don’t have and in stock in the United States. Now I’m on a waiting list with the job unfinished. Also the current listing price is way higher then I paid in October. It was under $300 when I got it. It’s not worth over that amount. It’s been 4 months still no replacement.

Bought this DeWalt 6" Surface Grinder kit (DWE46253) to use for for my residential remodeling company. We used to use scaler heads on jackhammers to remove thinset before we got our hands on this grinder. We also purchased the DeWalt DWV010 Dust Extractor which connected effortlessly right out of the box. The combination works wonders and the included diamond cup lasted quite a while. While I don't have an exact number, the included diamond cup has removed thousands of square feet of thinset. The DeWalt DWE46253 has plenty of power to grind through significantly thick layers of thinset with ease and the included D shaped handle is adjustable to maximize user efficiency. Using a diamond cup with a dust extractor is significantly faster than trying to use a scaler blade on a jackhammer. When we're not using this grinder for thinset removal, we slap on a tile blade for those complex tile cuts that are too annoying to do on our wet saw. If you're looking for a thinset removal tool that can multipurpose as a grinder, tile cutter, etc, this may be your grinder.

Good tool going to use once.

When paired with the proper blade, it makes the cut in stone feel like cutting through butter. It was so easy I accidentally cut too deep on my first try, because my previous grinder was a cheap brand and I got used to having to apply force for the cheap grinders to cut properly. It's high power, it got a good kick when you start up the machine, same for when you turn it off. That being said, the power is great for cutting and grinding stones and hard surfaces.

Works great, variable speeds, smooth, and never runs hot while continuous grinding.

Je l'utilise pour la colle a céramique et c'est très efficace et sans poussière WOW

When hooked up to a solid dust extractor there is virtually no dust.
