For added safety, the grinder is equipped with overload protection that turns the tool off if it gets into a bind. The kit includes a charger and two 3.0 Ah batteries to keep the angle grinder up and running, as well as a carrying bag to easily transport the grinder while on the job.

    Recently bought this grinder to get away from air lines in the shop. So far so good seems to have lots of power for battery one but eats batteries in about 15-20 mins. You xan buy adapter for unit so you can use dewalt and milwaukee batteries with it. That is what I plan to do.

    This thing is great, but like any high-performance tool, it needs to be fed the juice, I opted to get this as it comes with x2 3.AH batteries, i also have some 2.AH batteries but it runs through those quick.

    3.0 out of 5 stars Been waiting for this…
    Reviewed in Canada on November 30, 2024
    Verified Purchase
    I’m on the Dewalt 20v and Bosch 12v battery environments and for cost and logistics I try to stay in these battery lines.

    I’ve been waiting for a battery powered right angle die grinder for quite a while. I have the Dewalt strait die grinder but there are times a right angled one would be more effective or ergonomically better.
    I was happy to hear Bosch was releasing this unit earlier this year (2024) but at a crazy introductory kit price of over 350cad. I decided to wait and on Black Friday it finally came on sale for under 300 (including 2 x 3ah batteries). You can also just purchase the tool but I decided it was good to have the batteries.

    While I haven’t used it long, overall I’m quite pleased with this unit (probably more for just being able to get a cordless right angle unit).

    It is larger than expected and seems well built though it is rather plasticy which gives it an advanced homegamer feel. From a design perspective, I think the Milwaukee units are aimed more at professional users.
    I was also surprised that there is no LED light as on the Milwaukee and Dewalt cordless die grinders. Though this is not a deal breaker it is a nice to have . In a newly released tool in 2024, I just assumed one would have been cleverly incorporated by a major tool brand???

    As I stated previously in my reviews of Bosch’s 12vmax tools if I was starting over I would just invest in the Milwaukee 12v line. They have a more comprehensive 12v tool selection and innovate quickly.

    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.

    Reviewed in Mexico on September 30, 2024

    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.
