Grinder 18v or 40v ?
Good morning, I'm looking for a new grinder. I already have a couple of corded ones and I'm planning on getting one with 18V or 40V batteries, already have both 18V and 40V batteries for differential tools. Now that I've told you this, I know that all or most of you recommend I go straight for the 40V. But the question I'm asking myself is this: do I need a 40V? I mainly cut porcelain stoneware, and I sometimes cut rebar up to 16mm thick. I occasionally use the grinder to install electrical wiring in walls, and sometimes I use the disc specifically to sand the wall from old tile glue. Given all this information, do you think it makes sense for me to get the 40V grinder? For me, the only problem is that it's bulkier and heavier, and this is a very important factor for me. I work in apartment renovations, so I need a tool that isn't heavy.
Which models do you recommend?
