Comparison

The Makita GA5020Y is a good value for the price, with a powerful motor and a comfortable grip. However, it is not as powerful as the Bosch GWS 7-115 or the DeWalt DWE496. The Bosch GWS 7-115 is the most powerful of the three, but it is also the heaviest and most expensive. The DeWalt DWE496 is a good middle ground between the Makita GA5020Y and the Bosch GWS 7-115, with a powerful motor and a comfortable grip at a reasonable price.

Which one should you buy?

The best choice for you will depend on your needs and budget. If you need a powerful grinder that can handle heavy-duty tasks, the Bosch GWS 7-115 is a good option. If you are looking for a more affordable grinder that is still powerful enough for most tasks, the Makita GA5020Y is a good choice. And if you want a grinder that is lightweight and easy to use, the DeWalt DWE496 is a good option.

Additional considerations

In addition to the features listed in the table, you may also want to consider the following factors when choosing a grinder:

  • The type of work you will be doing. If you will be doing a lot of heavy-duty grinding, you will need a grinder with a powerful motor. If you will be doing more light-duty grinding, you can get away with a less powerful grinder.
  • The size of the grinder. If you will be working in tight spaces, you will need a grinder that is not too large.
  • The comfort of the grip. You will be using the grinder for extended periods of time, so it is important to choose a grinder with a comfortable grip.
  • The warranty. Most grinders come with a one-year warranty. However, some brands offer longer warranties.
