Great tool for its intended use
I purchased this angled grinder because I needed to get into tight spaces on metal sculptures that were difficult to do with my pneumatic die grinders. This tool works as advertised, it should be noted that I do not force the grinding, but let the tool use speed to do the job. The batteries last longer than I anticipated and the tool is ergonomically designed to be comfortable during long use. This is a great buy for my intended use and a welcomed addition to my toolbox.

Excellent Tool
Great tool that I didn't know existed. Always used pneumatic die-grinders. Battery does not last like a pneumatic one, but gets the job done, plenty of power, especially with the different setting levels. Nice set, size is good and price is decent for Bosch tools.

Good for light duty if using for metal work
All in all, it's satisfactory. I had higher expectations but I needed to be more realistic. Don't expect this to compete with an pneumatic angle die grinder. I tried carbide cutters and it will perform but obviously don't expect to hog. If you're deburring, then it's perfect. Roloc pads are about the best you can expect with this, again good for deburr. Guaranteed this would perform if it was 18V but would take away the compactness of the 12V. Do get the biggest 12V battery if you want better performance and longevity.

Good alternative to Milwaukee
I have both Bosch and Milwaukee 12v tools and batteries. I needed (or as my wife would say, I wanted lol) a compact grinder that accepted roloc discs. I initially wanted the Milwaukee version but this model rarely goes on sale. After further research I found this Bosch model. I have their 12v orbital sander and I love it. So I purchased it on sale and took a chance. I can tell you I am very impressed. It has power and it is extremely quiet. It is very light to handle and fits well in the hand. Milwaukee does make excellent tools but for my needs and budget, this tool checks all the boxes.

2 baterías de 3A. Si gasta considerablemente rápido la batería, por ello trae 2 incluidas en el kit. No he puesto atención a la duración de la misma quizá 30 min constantes. Es lo de menos, con 2 es más que perfecto. La compre para quitar óxido a láminas de equipos médicos y pintarlas. Hace poco hice una estructura de ángulo de 3/4 de fierro negro para poner un techo a una ventana. Tuve que limpiar los ángulos que se estaban manchando con óxido. La grandísima ventaja es que en AliE xpress y acá mismo hay muchos insumos para ser usados con los discos de 2 pulgadas, incluso se puede usar discos de 1”. Con el adaptador de 1”. El madril Acepta zancos desde 6 hasta 6.34mm (1/4). Solo que en 6mm se tiene que apretar a tope. De preferencia que sea de 6.3mm o 1/4. Es extremadamente cómodo, una exquisitez el tenerlo en la mano. Limpia el metal de óxido con una deliciosa facilidad. Esta herramienta de verdad que enamora. Ya le hice el amor 3 veces seguidas la neta.

Amazing tool. It's so light and versatile, powerful enough and fits all the 1/4" bits. I regret not getting the 3 amp batteries though. It eats power.
