I actually need a bigger grinde like 230mm makita or Bosch will be visiting musina on Friday?

Based on the search results, I would recommend either the Makita Angle Grinder 230MM 2200W GA9020 for R2555 or the Makita Angle Grinder GA9050 230MM 2000W for R3319.36. Both are quality 230mm Makita angle grinders that will serve you well for your projects. The Makita brand is highly regarded for durability and performance. These models have strong 2200W or 2000W motors to easily grind through tough materials. They should be perfect for what you need and are affordable options that can be delivered to you in Musina by Friday. Let me know if you need any other details on these grinders to help with your decision. I'm afraid the search results did not contain any Bosch angle grinders that met your specifications.
