Cordless Brush Angle Grinder Kit, 19500rpm Mini Electric Angle Grinding Tool with 2pcs 16.8V 2000mAh Batteries and 5-Cutting Discs, Grinder Handheld Cutter for Metal Wood

Works just fine ,no issues.I am installing a new bumper on my 4 Runner which requires cutting off the old plastic bumper cover and part of both rear fenders.Once the area to cut was taped and marked it was a simple matter of using the grinder to cut along the line.The entire job and cleaning the rough edges was done on 1 battery. I'll be replacing the front bumper as well and will use the new grinder for that.

Small 3” cordless grinder. Perfect for sharpening lawn tractor blades without having to take them off. Grinding pads and disks must be purchased on line as Harb. Freight, Lowe’s, Home Depot and others don’t carry anything that small. Many available on line Amazon. Well built. High speed motor comes with two batteries which is great. Highly recommend this product.

This is the real deal, the one to get. Works like a champ. Good battery life and power. Nice attachments.

I bought this little grinder to help a friend in case we had to cut some metal and we had to end up cutting 1/4 inch steel about 3 inches wide off of a fixture. It worked great! It is a great value and I was afraid I was going to mess it up but it was tough and got the job done. I have only used it once so I can’t speak on battery life but it comes with two battery packs which is awesome. Even if it craps out the next time I use it - I don’t think it will - I am still way ahead for the cost. Great buy!

Could easily be better built, and it would last a lot longer. Some people are saying it is too noisy. Others say it got so hot it stopped working in a minute. But why? I'm a mechanical engineer, and very curious, so I got one of these brand new and after noticing it is indeed very noisy, and the noise itself seems like something is loose inside, I've opened it. This thing has one wheel bearing mounted on the motor axle, very close to the end point where you attach the cutting disk. Good, it has to have one right there to provide strength as you torque the cutting disk onto the material you're cutting. But this wheel bearing outer shell is held only by the plastic enclosure, and it's loose. Even tightening the two screws really well on that neck of the tool, does not prevent the whole wheel bearing from spinning inside the tool. Spinning not just its core with the motor axle, but the whole bearing body is spinning, which causes a lot of friction with the plastic enclosure, and could eventually melt it. Fixed by adding a layer of aluminum around the wheel bearing so when compressing the plastic shells back together, the bearing is firmly pressed against, and no more noises that are not supposed to be there. The motor now runs smooth, as quiet as it runs outside the shell, and I notice no heat that would rather be abnormal. It is not a tool to run for many many minutes non-stop anyway. This is for quick jobs, run and stop, run and stop, but still, the way the wheel bearing was loose inside is not something acceptable even for a minute run. I don't think many people would be able to do this fix, and I don't recommend trying, unless you have the experience, so better just buy a well known quality tool instead. I don't recommend this tool. If this post survives, I'll get back to it and post some pictures.

I love this little grinder. I appreciate having 2 batteries that comes with it. Makes my projects complete mush faster. Also like the multiple blades, makes this piece so much handier.

Got this lil bugger for tractor projects, so far so good, got some fresh cutting disks from diablo brand- and it cuts great, took the guards off to get closer to where i needed to get to-works in places bigger and more powerful angle grinders just simply cant reach!!!

Already have several full size grinders. But don't always need that amount of power. On the flip side tool doesn't have a lot of power. But still has been sufficient for cutting through iron pipe and whatnot. And appreciate it's ~½ as loud as full size tool. For it's size and weight am comfortable to used with one-handed operation. Wheel spins up instantly but doesn't have enough rotational torque for it to jump when you pull the trigger.Arbor size is 10mm. Common 3/8" arbor blades will not fit. (Even though discs are labeled as 3/8").Powered by a standard brushed RS-550 motor. Replacement motors or brush heads are plentiful. And transmission is a 4:1 ratio (12T - 48T) so actual speed of the wheel is closer to 4000RPM (unloaded). The guard can be rotated but need to loosen 3 tiny ant sized screws to do so. Not the best design.The 2000mAh battery claim is very inaccurate. Disassembled the packs and tested several cells (unbranded, no labeling), actual capacity was ~1250mAh. For the light tasks this tool is intended for it's sufficient but that is still gross false advertising. Packs have (very basic) integrated BMS + charging circuity. Power adapter is rated at 16.5V/1A with a common barrel connector. Do not attempt to charge with adapter of any higher rating. As stated the circuitry is very basic and could both damage the packs and lead to overcharging.Molded case is kinda meh. Weakest part is the hinge, expect will need to repair with zip ties in short order. No complaints with the actual latches as yet.It's not a good tool. But it's cheap and not expecting Milwaukee quality. For what I intend to get out of it though it's OK.
