Price Comparison

The Angle Grinder Cordless for De-walt 20V Max Battery is priced at $69.99, making it about 17% cheaper than the AOBEN Cordless Angle Grinder, which retails for $79.99. This price difference can be significant for budget-conscious buyers who are looking to invest in a reliable tool without overspending. The price point of the De-walt compatible grinder may attract those already invested in the De-walt ecosystem, while the AOBEN offers a competitive price with added features, which is worth considering for potential buyers.

Power and Performance

When it comes to power and performance, the AOBEN Cordless Angle Grinder takes the lead with a maximum speed of 9,500 RPM compared to the De-walt compatible grinder's top speed of 8,500 RPM. The brushless motor in both products enhances their efficiency, but the AOBEN's higher RPM indicates a potential for faster cutting and grinding tasks. This difference in speed may appeal to users who require robust performance for demanding applications, making the AOBEN a strong contender for heavy-duty work.

Battery and Runtime

The AOBEN grinder comes with two 21V 4.0Ah batteries, ensuring a longer runtime and the convenience of having a backup battery. In contrast, the De-walt compatible grinder is sold as a tool only, requiring users to purchase a compatible De-walt battery separately. This could lead to additional costs for De-walt users who do not already own compatible batteries. The inclusion of two batteries in the AOBEN kit provides an advantage for those who need extended operational time without interruptions, making it more versatile for both indoor and outdoor tasks.

Speed Settings

Both grinders offer three adjustable speed settings, but they differ in their range and maximum speed. The De-walt compatible grinder ranges from 3,000 RPM to 8,500 RPM, while the AOBEN provides speeds up to 9,500 RPM. This broader speed range in the AOBEN allows for more precise control over various tasks, such as grinding, cutting, and polishing. Users looking for greater versatility in speed options may find the AOBEN more appealing due to its higher maximum RPM and adjustable settings that cater to different materials and applications.

Ergonomic Design

The De-walt compatible grinder features a comfortable ergonomic design aimed at reducing user fatigue during prolonged use. It includes anti-slip auxiliary handles for better grip and stability. The AOBEN also emphasizes ergonomic design with its compact and handy structure. While both tools prioritize user comfort, the AOBEN's design may be slightly more advantageous due to its additional features, such as the auxiliary handle for better control. This focus on ergonomics is essential for professionals who spend extended hours using these tools.

Safety Features

In terms of safety, both grinders include protective features to ensure user safety during operation. The De-walt grinder is equipped with a protective guard that blocks sparks and debris, while the AOBEN comes with two wheel guards to shield users from flying chips and sparks. The AOBEN’s inclusion of multiple guards provides an extra level of safety, especially for those engaged in more hazardous cutting operations. The commitment to safety in both tools is commendable, but the enhanced protection in the AOBEN may offer peace of mind for heavy-duty users.

Customer Reception

The AOBEN Cordless Angle Grinder enjoys a higher sales rank at 15,649 compared to the De-walt compatible grinder's rank of 27,714. This higher rank may indicate stronger customer reception and satisfaction, suggesting that users find the AOBEN to be a more reliable or effective choice. Customer feedback often reflects real-world performance and satisfaction, so the AOBEN's popularity could be a deciding factor for potential buyers looking for a trusted tool in their toolkit.

Which should you buy?

In conclusion, the choice between the Angle Grinder Cordless for De-walt 20V Max Battery and the AOBEN Cordless Angle Grinder ultimately depends on user needs and preferences. The De-walt grinder is slightly more affordable and is compatible with existing De-walt batteries, making it a great option for current De-walt users. However, the AOBEN offers superior power, better battery options, and additional safety features, making it a compelling choice for those who prioritize performance and versatility. If you require a robust tool for demanding applications, the AOBEN may be the better investment, while budget-conscious users may find the De-walt grinder meets their needs effectively.
