Price Comparison
The AVID POWER Angle Grinder is priced at $42.99, while the Cordless Angle Grinder is listed at $49.99. This makes the AVID POWER grinder about 14% cheaper than its competitor. If budget is a primary concern, the AVID POWER Angle Grinder provides a more cost-effective option without sacrificing essential features. The price difference of $7 may seem modest, but for those looking to save on tools for home projects, every dollar counts.
Power and Performance
The AVID POWER Angle Grinder boasts a powerful 6.5 Amp motor with a maximum output of 750W, generating a no-load speed of 11,500 RPM. In contrast, the Cordless Angle Grinder features a brushless motor that delivers a maximum speed of 10,000 RPM. While both grinders are efficient, the AVID POWER model outperforms the Cordless version in sheer RPM, making it better suited for heavier grinding tasks. If speed and power are your priorities, the AVID POWER grinder is the clear winner.
Versatility of Use
Versatility is a key factor when choosing an angle grinder. The AVID POWER Angle Grinder comes with essential cutting and grinding wheels, making it ready to tackle various metal projects straight out of the box. The Cordless Angle Grinder, however, requires the purchase of wheels separately, which adds to the overall cost and inconvenience. For those who want a tool that can be immediately used for multiple applications, the AVID POWER grinder offers greater value and functionality.
Safety Features
Safety is paramount when using power tools. The AVID POWER Angle Grinder includes a screw-on guard that can be adjusted to prevent injury, along with a side handle designed for better control. The Cordless Angle Grinder takes safety a step further with a protective switch, quick-adjust guard, and power failure protection that stops the tool in 1.5 seconds after releasing the switch. While both grinders have commendable safety features, the Cordless model's advanced safety measures may appeal to users looking for extra reassurance during operation.
Weight and Ergonomics
The AVID POWER Angle Grinder weighs only 3.20 lbs, making it lightweight and easy to handle for prolonged use. This design helps reduce fatigue during extended projects. In comparison, while the weight of the Cordless Angle Grinder is not specified, its ergonomic design includes an adjustable handle that accommodates both left and right-handed users. The AVID POWER grinder's lighter weight may provide an advantage for users who prioritize ease of handling and comfort during tasks.
Battery and Power Source
The Cordless Angle Grinder operates on a Dewalt 20V MAX battery, which allows for greater mobility and eliminates the hassle of cords. However, it's important to note that no battery is included with the tool, which could lead to additional expenses if the user does not already own compatible batteries. The AVID POWER Angle Grinder is an electric model, providing consistent power without the need to worry about battery life. Depending on your work environment, the choice between the portability of the Cordless model and the consistent power of the AVID POWER model is significant.
Application Range
When it comes to applications, the AVID POWER Angle Grinder is primarily designed for cutting and grinding metal, alongside the potential for handling tiles, stones, and concrete with additional wheel purchases. The Cordless Angle Grinder claims to be versatile enough for metal cutting, surface treatment, and wood polishing, making it suitable for a wider array of tasks. However, its effectiveness will ultimately depend on the quality of the wheels selected. If you need a grinder with broader application claims, the Cordless Angle Grinder may be more appealing.
Which should you buy?
Choosing between the AVID POWER Angle Grinder and the Cordless Angle Grinder boils down to personal preference and specific needs. The AVID POWER model stands out for its lower price, higher RPM, and included accessories, making it ideal for users focused on cost-effectiveness and immediate functionality. Conversely, the Cordless Angle Grinder offers the advantage of mobility and advanced safety features, appealing to those who prioritize these aspects in their work. Ultimately, if you value performance and immediate usability, the AVID POWER Angle Grinder is the better option. If portability and safety are your top concerns, then consider the Cordless Angle Grinder.
