Overview of the DEWALT Angle Grinders

When comparing the DEWALT Angle Grinder Tool, 4-1/2-Inch to 5-Inch, Trigger Switch (DWE43116) and the DEWALT Angle Grinder, 7-Inch, 13-Amp, 8,000 RPM, With Dust Ejection System, Corded (DW840), you'll find distinct differences in design and functionality. The DWE43116 is priced at $158.99, while the DW840 is available for $166.02, making the DWE43116 about 4.1% cheaper. Both tools are built for performance, but their specifications cater to different tasks and user preferences.

Motor Performance and Speed

The DEWALT Angle Grinder Tool, DWE43116, is powered by a robust 13 Amp motor with a rating of 9,000 RPM, which makes it suitable for high-speed grinding tasks. In contrast, the DEWALT Angle Grinder, DW840, also features a 13 Amp motor but operates at a lower speed of 8,000 RPM. While both motors provide strong performance, the higher RPM of the DWE43116 allows for quicker grinding and cutting, giving it an edge in speed-oriented tasks.

Design and Ergonomics

In terms of design, the DWE43116 weighs only 5.7 lbs, making it lightweight and easy to handle for extended periods. This grinder is equipped with a trigger grip, enhancing user control. The DW840, while slightly heavier, is designed with a rear-handle grip area that aims to improve comfort and control. However, its 7-inch size may make it less maneuverable compared to the smaller DWE43116, especially in tight spaces.

Dust Ejection System

Both models include a Dust Ejection System, but they serve slightly different purposes. The DWE43116's system is specifically designed to eject harmful dust and debris that can enter through air intake vents, thus prolonging the tool's lifespan. The DW840 also features a dust ejection system but focuses on preventing debris from entering the motor, enhancing durability during operation. This means that while both protect the grinder, the DWE43116 offers more proactive dust management.

Safety Features

Safety is paramount when operating power tools, and both grinders come equipped with essential safety features. The DW840 includes an adjustable guard that can be directed to redirect sparks away from the user, which is an important consideration for safety during grinding tasks. The DWE43116, on the other hand, does not explicitly mention this feature but includes a side handle for added stability and control. This lack of an adjustable guard could be a deciding factor for users prioritizing spark protection.

Versatility and Applications

The versatility of each grinder can significantly affect your purchasing decision. The DWE43116 is designed for high-performance grinding and cutting applications, making it ideal for professionals who require a tool that can handle various tasks. Meanwhile, the DW840 is marketed as a medium angle grinder, indicating it can handle a range of metal grinding and cutting applications but may be less effective for high-speed tasks compared to the DWE43116. This distinction can guide users based on their specific needs.

Price Comparison

The DWE43116 is priced at $158.99, while the DW840 costs $166.02, showing a price difference of $7.03. This makes the DWE43116 about 4.1% cheaper than the DW840. For budget-conscious buyers, the lower price of the DWE43116 may make it a more attractive option. However, the slightly higher price of the DW840 may be justified for those who value its specific features, such as the adjustable guard.

Which should you buy?

Ultimately, deciding between the DEWALT Angle Grinder Tool, DWE43116, and the DEWALT Angle Grinder, DW840, depends on your specific needs and preferences. If you prioritize higher RPM for faster cutting and a lighter tool for extended use, the DWE43116 is the better choice. However, if your focus is on safety features like spark redirection and you don’t mind the extra weight, the DW840 could serve you well despite its higher price. Both grinders offer solid performance, but understanding their differences will help you make the best choice for your projects.
