Overview of the Products
In this comparison, we look at two angle grinders: the AVID POWER Angle Grinder and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder. The AVID POWER model is priced at $42.99, while the DEWALT model comes in at $144.50, making the AVID POWER grinder about 70% cheaper. This significant price difference invites further exploration into their features and performance to determine which tool offers better value for specific needs.
Power and Performance
The DEWALT FLEXVOLT ADVANTAGE offers superior power with a maximum output of 1,550 watts, while the AVID POWER grinder has a maximum output of 750 watts. This gives the DEWALT model an edge in terms of performance, especially for tougher jobs. Additionally, the DEWALT grinder can reach up to 9,000 RPM, whereas the AVID POWER grinder operates at 11,500 RPM. Despite the lower maximum output, the AVID POWER grinder may still be suitable for lighter home projects due to its higher no-load speed.
Safety Features
Safety is crucial when using power tools, and both grinders offer unique safety features. The DEWALT FLEXVOLT ADVANTAGE includes a Kickback Brake that rapidly stops the wheel and shuts off the grinder in case of a bind-up, providing enhanced safety during operation. Moreover, it features an E-CLUTCH system that shuts down the motor within a fraction of a second when a pinch or stall is detected. The AVID POWER grinder features a screw-on guard that can be adjusted for safety and a side handle for better control, making it user-friendly for extended use.
Handling and Usability
The AVID POWER Angle Grinder weighs only 3.20 lbs, making it lightweight and easy to handle for prolonged periods without causing fatigue. It also has a two-position side handle that accommodates both left and right-handed users, enhancing its usability. On the other hand, the DEWALT grinder's design allows for compatibility with all DEWALT 20V MAX* and FLEXVOLT batteries, making it versatile for users who already own DEWALT tools. While the DEWALT grinder may weigh slightly more, its ergonomic design is tailored for user comfort.
Included Accessories
When it comes to accessories, the AVID POWER grinder includes two cutting wheels and two grinding wheels, making it ready for use right out of the box. This inclusion of essential accessories adds value for those who may not have them on hand. In contrast, the DEWALT FLEXVOLT ADVANTAGE is sold as a tool-only option, requiring users to purchase batteries and chargers separately. This could lead to additional costs for users who do not already own compatible DEWALT batteries.
Maintenance and Longevity
The AVID POWER grinder is equipped with a brushed motor, which means replacement carbon brushes are readily available to extend its service life. Users can easily replace the brushes when they wear out. In comparison, the DEWALT grinder's brushless motor offers longer life and less maintenance, as it does not require brush replacements. This difference might sway buyers who prefer low-maintenance options over those who don’t mind performing occasional upkeep.
Brand Reputation and Ranking
In terms of popularity, the DEWALT FLEXVOLT ADVANTAGE ranks higher in sales with a bestseller rank of 14,755 compared to the AVID POWER grinder's rank of 22,682. This may indicate a stronger brand reputation and customer trust for DEWALT, often associated with professional-grade tools. However, the AVID POWER grinder's lower price point may attract DIY enthusiasts and those looking for cost-effective solutions for home projects.
Which should you buy?
Choosing between the AVID POWER Angle Grinder and the DEWALT FLEXVOLT ADVANTAGE largely depends on your specific needs and budget. If you require a powerful tool for heavy-duty tasks and are willing to invest more upfront, the DEWALT model is a robust choice with advanced safety features. However, if you are looking for an affordable option for light-duty projects, the AVID POWER grinder offers great value with decent performance and essential accessories included. Ultimately, consider your project requirements, budget, and brand loyalty before making a decision.
