Buying Advice:

This section was made to help you understand more about angle grinders. Getting the right grinder takes time. But knowing the right specs to look for makes the process a lot easier. Take a look at this section if you're still confused on what to buy.


The motor power is the biggest thing to consider when looking for an angle grinder. While a low RPM might be good for home usage, it's not worth your money. You should get an angle grinder with an RPM of 5,000 or above.

At this setting, you'll be able to complete at least 90% of your metalworking and DIY tasks. But, if you're a professional who needs to make industrial style cuts, then an RPM of over 10,000 will work the best for you.

Since the Dewalt DCG412B has an RPM of 8,000, it's motor speed is at a respectable balance. You'll have enough speed to cut through all of your metals in one pass. And, it's at a good enough speed where you won't waste too much energy when using the machine.

Wheel Size

Your wheel size is also something to remember when out shopping. Your angle grinder should come at a size 4-1/2 or higher. This makes it easier for you to do basic house hold cutting projects and polish metals without experiencing issues.


If you need to do hard tasks such as cutting pipes and polishing steel, then you'll want a wheel size of 9 inches. This size makes it easy to cut through strong objects and are heavy to hold. Because of this fact, you'll have to practice using a smaller grinder wheel to get acquainted with these large machines.


You'll need to have a handle that's easy to hold. Some shoppers make the mistake of buying a larger grinder wheel first. This will lead to failing to make accurate cuts. As we've stated earlier, start with a small angle grinder with a safer handle to use.

The best angle grinders have an ergonomic handle. These handles have a rubberized grip and prevents vibration. Vibration will negatively affect your performance and cause you to make the wrong cut. Invest in an angle grinder with an anti-vibration feature to remain comfortable when grinding your metals.
