The DeWalt DWE402 is a good value for the price. It is made in the USA and has a reputation for durability. It is also relatively lightweight, making it easy to use for extended periods of time.

The Makita GA4530 is a bit more expensive than the DeWalt DWE402, but it has a few more features, such as a lock-on button and a vibration-reduction system. It is also made in Japan, which is known for its high-quality manufacturing standards.

The Bosch GWS 660 is the most expensive of the three models, but it also has the most features. It has a lock-on button, a vibration-reduction system, and a dust collection system. It is also made in Germany, which is known for its precision engineering.

Which one to choose?

The best model for you will depend on your needs and budget. If you are looking for a good value and a durable tool, the DeWalt DWE402 is a good option. If you want a few more features and are willing to pay more, the Makita GA4530 is a good choice. And if you want the most features and the best quality, the Bosch GWS 660 is the best option.

Additional considerations:

• Power: The amperage of an angle grinder determines its power. The higher the amperage, the more powerful the grinder.
• Speed: The RPM of an angle grinder determines its speed. The higher the RPM, the faster the grinder will cut.
• Features: Some angle grinders have additional features, such as a lock-on button, a vibration-reduction system, or a dust collection system. These features can make the grinder more comfortable and efficient to use.
• Price: Angle grinders range in price from around $50 to $200. The price will depend on the features, power, and quality of the grinder.
