DEWALT 5 in. Brushless Surfacing Grin

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.

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.

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
