Both pneumatic and electric grinders are used throughout industries and for different applications. However, how do you know which ones work best for you? In some cases, electrical tools may be your only choice due to access to only one power supply, but many places now have access to compressed air too, so the options open up.

Which grinder should you choose for your application?

Difference Between Pneumatic & Electric Grinders

In this assessment, we will be looking at three different factors to deduce a conclusion: performance, ergonomics, and functionality of both pneumatic and electric grinders.


The performance of each tool refers to the power of each tool; the full power of each tool is stated on the label. High performance typically means high productivity as it will result in the biggest material removal.

Electric grinders are able to reach their full power, however it is easy to overload the tool and, when under constant load whilst grinding, it is very likely that the motor will get damaged. Pneumatic grinders are also able to reach their full power with ease but with no risk of overloading or damaging the motor. Therefore, pneumatic grinders have a higher performance and higher productivity.


The ergonomics of each tool refers to the comfort of the equipment design, such as weight, handle and grip, as well as the comfort of the operation, such as noise level and vibration. These factors relate to productivity as they directly affect the operator and day-to-day jobs.

Pneumatic grinders have a better power to weight ratio than electric grinders, meaning they are more ergonomically effective. Also, as they can maintain stated power a lot easier, pneumatic tools produce less vibrations and noise than electric ones.


The functionality of each tool refers to how easily operated they are. Considerations such as whether they can be operated with working gloves, how easy it is to change position, etc. should be addressed within this category.

The main advantage with electric grinders is the easy installation and flexibility of the tool. The most common power source for any buildings is electric, so this provides great functionality, accessibility and availability. However, pneumatic grinders have the ability to work in wet environments unlike electric ones, giving them more versatility. Also, compressed air is quickly becoming an essential power source within the manufacturing industry increasing its accessible.

Pneumatic Vs. Electric – What Grinder Should You Choose?

When it comes to grinding, you need to pick a tool that will not weigh you down or cause you stress and strain, is reliable enough not to overload mid-operation and work in any environment, all while being powerful and productive. Pneumatic grinders are the best tool for the job, and you can find the one you want by coming to us.
