Bosch are quality tools
I didn't expect this grinder to be so small and portable, it looks a lot thicker in the picture on the site, but I am very happy with the product, it came with two grinder wheels: one a little thick that says "Metal Grinding Wheel" the other is really thin and says "Metal Cutting Wheel", that's the one I bought it for but I didn't realize I didn't order a battery or charger so now I'm waiting for them to come in so I can cut some metal or aluminum roofing panels I got for now.

Good
This machine fulfills its function, it has excellent quality, it doesn't break down like others, so you can cut with confidence without fear of it breaking unexpectedly.

Very handy little tool. But switch is a pain in the a**.
Very handy little tool. Good for filing on wood projects too. Like some others, I find the switch to be a pain, in that it won't stay on when tool is running. I have several other Bosch cordless tools with finicky switches. So Bosch has design problems with switches on otherwise excellent tools.

Good product
Good little grinder but it has a bad design on the switch. Very hard to keep the switch on and keep the grinder running. I do think it's a flaw in design. I returned the first one because of the switch but the 2nd one has the same problem. Thinking it might be operator error, we kept it and used it. Since we don't use it often, the warranty ran out and we could not return the tool. I need to call the company to get some feedback. The size is great for my small hands. Also the batteries don't hold a long charge. I use for Horse Hoof Trimming. I have 2 genuine batteries so I can switch them out while I work, if they get slow. The tool works but the switch is a pain to use. If I could, I would return this. Price is too high for the hassle with the switch

Fits in tight places.
This is a great little grinder if you’ve already got the Bosch 12 V ecosystem. It’s really handy because it fits in very tight places where my Dewalt 20 V max grinder won’t fit.

Bosch, Quality Tools
Why did you pick this product vs others?: It’s what I wanted, I have multiple Bosch handheld electrical tools and operation functioned great.

Powerful and light weight, received in good condition.

Simple, small, yet strong enough to cut 1/2 inch bolts easy. It's a pain to set up a corded makita when you have just a small job. This unit is perfect for that and easy to store and handle.

la herramienta se persibe de exelente calidad, es muy pequeña y compacta, se siente una herramienta solida que será duradera, en la caja se incluye el grinder 2 discos de corte y una llave hexagonal, los discos que se incluyen cuando recibí la herramienta ya se habían caducado, el eje es M10 que es el standard en los productos europeos y asiáticos, cómo nota el grinder es fabricado en Alemania y no en algún país asiático como muchas de las herramientas de Bosch.

Práctica, útil y cómoda de usar! Ideal para trabajos en casa ! Los discos que trae son 2 y son básicos, recomiendo comprar esta herramienta.
