    • Great tool with no cord!
I've used corded angle grinders for many years and I never expected a cordless angle grinder to be worthwhile. I was pleasantly surprised that this angle grinder works amazingly well. With steady use, the battery will discharge after several minutes, so it's helpful to have a second battery on standby. However, for most standard applications it's worth not dealing with a cord getting in the way. This has plenty of power to work as expected. ... show more

    • Great little grinder!
I use these at work cutting rebar, with a wire wheel, and with a concrete grinding wheel on a daily basis. It’s a well-designed grinder that cuts and grinds very well. We have several, and they have all been in use for years, now. They are easily assembled, and switching blades and wheels is easy. Very durable grinder I used for years, and now I have my own. ... show more

    • Didn't really need it but made quick work on couple small jobs.
Worked great for the couple quick jobs I used it I on, but does run down batteries fairly quick. Otherwise it appears to be a nice well built tool.

    • Well designed.
So far just used for twisted wire brush on rust, worked great, with little drain on a generic 4Ah battery. Weight is fine, balance good. I like the hex wrench system for tightening the arbor screw; much more likely to be readily available if the provided wrench is lost or forgotten. 6K RPM's plenty adequate for light to moderate jobs. Tool seems well thought out to me. The complaints about stopping with overheating and binding are a little hard to understand given that these are built in safety and longevity features thoroughly covered in the instructions. This is not equal to a plug in tool, as is true of all battery powered tools. I expect if a constant heavy load is put on it the battery will run down quickly, and the motor is likely to overheat given the constraints of battery powered tools. Just physics, folks. If you want 10K+ RPM and ability to do constant heavy cutting or grinding, use something with a cord! ... show more
