When choosing one, you must pay attention to the tool’s speed, power, and weight.
To help you out with your choice, we’ve put together this guide that highlights the most important features to check before buying. Then, have a look at our top picks to find the best 7-inch angle grinder for you.
How to Choose an Angle Grinder
Choosing the best angle grinder goes beyond a mere brand preference. While the tool you like must offer great value for money, you must also check the following three essential criteria.
Power
Like for all power tools, an angle grinder’s power is expressed in watts, and the math is simple, the many watts your tool has, the better. Manufacturers rarely disclose their tool’s wattage output, but luckily, the number is easy to calculate.
All you need to know is the voltage and amperage of the tool, then multiply the two numbers.
In broad terms, you’ll need an angle grinder capable of outputting at least 500 watts, which is more or less the equivalent of 1,000 watts input.
Speed
Expressed in revolutions per minute, an angle grinder’s speed is another thing to check. Again, you want as many revolutions per minute as possible. Most machines spin at speeds from 5,000 to 10,000 RPM, although some high-end units may reach 12,000 RPM.
What you must keep in mind is that a higher speed means a lower cutting time, which ultimately means less heat and less wear-out of the blade.
However, when assessing speed also consider the discs you’re going to use. Depending on the materials supposed to cut, some discs may not support high speeds. Using a disc at a higher speed could result in injury, so make sure to choose accordingly. If in doubt, invest in a grinder with adjustable speed settings.
Discs
Last but not least, you must consider the discs. Most angle grinders are compatible with most types of discs. Here are the most popular options.
With all this in mind, let’s now have a look at the best 7-inch angle grinders on the market, so you can pick the right one for you.
