The AVID POWER grinder is priced at $56.99, while the Bosch model is slightly more expensive at $79.00, making it about 17% pricier. Understanding their distinct functionalities will help you choose the right tool for your projects.

Motor Power and Performance

The AVID POWER Angle Grinder features a robust 1,000W motor, which allows it to reach an impressive no-load speed of 11,500 RPM. In contrast, the Bosch GWS8-45 is equipped with a slightly less powerful 7.5 amp motor that delivers a maximum speed of 11,000 RPM. While both grinders provide excellent performance, the AVID POWER model offers higher speed, which may be beneficial for demanding cutting and grinding tasks.

Design and Ergonomics

In terms of design, the Bosch GWS8-45 stands out with its slim-grip design, which contributes to outstanding user comfort, particularly during extended use. The AVID POWER grinder, while slightly bulkier, includes a paddle switch with a lock-on button for continuous operation, reducing user fatigue. Both grinders have a two-position side handle that enhances control, but the comfort level may differ based on individual preferences.

Safety Features

Safety is paramount when working with power tools. The AVID POWER Angle Grinder comes with a wheel guard designed to protect users from flying sparks and debris, enhancing safety during operation. On the other hand, the Bosch GWS8-45 features a burst-protection guard that allows for quick adjustments without compromising user security. Both models prioritize user safety, but the specific features may appeal differently to various users.

Durability and Maintenance

Durability is a critical aspect of any tool. The Bosch GWS8-45 is designed with durable carbon brushes that extend the tool's life and includes a Service Minder brush system that eliminates guesswork by shutting off the grinder when maintenance is needed. While the AVID POWER grinder does not highlight its maintenance features, it is built for heavy-duty use with its sturdy construction. Users may find the Bosch model more reliable in the long run due to its advanced maintenance features.

Included Accessories

This makes it an attractive option for users looking to get started right away without needing additional purchases. The Bosch GWS8-45, however, does not specify included accessories, which may require additional investment for users to fully utilize the tool.

Customer Satisfaction and Popularity

The AVID POWER Angle Grinder has a sales rank of 28,013, indicating a reasonable level of popularity among consumers. In comparison, the Bosch GWS8-45 has a slightly lower sales rank at 30,612. While both grinders are well-received, the AVID POWER model seems to attract slightly more attention in the market, potentially due to its price point and included accessories.

Which should you buy?

Choosing between the AVID POWER Angle Grinder and the Bosch GWS8-45 depends on your specific needs and preferences. The AVID POWER model is a solid choice for those looking for a powerful, cost-effective grinder with a comprehensive accessory package.
