I need to bolt an L-beam to the basement wall that will support a covering over the basement entrance. It turns out that the basement wall is not straight but makes a kink along the relevant stretch. Probably, two concrete wall elements are not properly aligned and form a small angle with each other. In the wall, there are pin bolts that supported a kitchen staircase that I want to use for the beam (I will supplement with some new ones set in anchor grout). These are not long enough to accommodate the irregularities, and even if they were, I do not want to use thick shims.
Therefore, I would like to level out part of the wall through, for example, grinding. However, quite a bit would need to be ground away, I believe between 500 and 1500 cm3, so I am considering whether it is feasible and what equipment should be used besides a dust filter mask. Based on my previous experiences with the concrete, it is hard quality concrete (requires a proper hammer drill for drilling, a hammer drill alone does not work). Cutting discs are optimized for different materials but are hardly suitable for grinding down a flat surface. Perhaps one can grind grooves with them, knock out the intermediate residues, and in this way have a smaller flat grinding job. Flap discs are indeed more intended for flat grinding, but I have not seen them for different materials, and those that exist are primarily intended for steel?
All serious suggestions on how to handle this problem are gratefully received.

Drive with a concrete grinder and diamond cup wheel that wrote over.
Alright. Either you go to Ramirent and rent a Hilti BG 150 or put on the full mask and use the angle grinder with a grinding cup. For example https://www.jula.se/catalog/verktyg...deller/sliprondeller/diamantslipskiva-016001/
