Your cart is empty.The Bosch GWS12V-30 12V Max 3 In. Angle Grinder is ideal for the pro who needs a compact powerhouse to get to those quick, difficult cuts in tight spaces other tools can't. With its brushless motor design and optimized gear structure, this efficient grinder produces 19,500 no-load rpm at only 1.5 Lbs. (tool only, not including battery). The grinder was engineered to fit the palm of a user’s hand, for outstanding ergonomics and control. This versatile tool is powerful enough to cut threaded rod, strut, conduit, tile and more. It features an innovative gear-mount design for fast wheel change; just pull the locking clip and unscrew the spindle screw. It also features fast braking time, stopping the wheel after the grinder is turned off.

As the conflicting evaluations start, the machines are only excellent if you indeed use them for small projects. The benefit of this machine is its small size; the disadvantage is that its small size makes it a poor choice for large projects where a full fine angle grinder is needed -- at least IMHO. For small projects it was terrific. I cut 24-high quality metal screws in a row quickly and easily on one charge without problem.

Strong little grinder. After just a few uses the small tab that keeps the sliding switch engaged has worn down, and the switch disengages when the tool encounters any amount of vibration. I have to continually hold the switch in place to run the grinder. Good battery life, but after running the grinder for a bit the battery needs to be reset in the housing for it to make contact. Overall a good mini grinder and gets the job done with some tweaking.

I didn't need this grinder right away, but eventually I may need one.I already have many Bosch 12V tools and batteries, so this is a perfect addition.

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.

I finally purchased this grinder after reading positive reviews. Never actually used it because it stopped working after 3 minutes. Turned off and on and sometimes it would come on and sometimes not. Battery indicator shows not power even after charging new battery. I was able to return it to Amazon.Due to the positive reviews I ordered another one immediately believing my experience was an isolated case.The second grinder did the same only much worse than the first. Believing the problem is with the switch or the battery connection I had my husband put the battery on and take it off. No difference, it still does not work consistently.Planned to use this for trimming horse’s hooves. Was getting horse use to sound which is why it wasn’t actually used, but just turned on.The battery is very difficult to get off and if you don’t have strong hands you likely won’t be able to get it off the grinder.After reading negative reviews, I see other people have had the same issue with this grinder.Very disappointed.

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.
