Angle grinders are handheld power tools mostly used to grind and polish different materials. This versatile tool is used for grinding metal and cutting tiles, as well as sanding, polishing and sharpening. You can easily sharpen blades and cut steels too!
Maybe you are looking to buy an angle grinder for the first time, or simply replacing your dad’s old one. So, you don’t know what to look for when buying this power tool?
There is no need to worry, as this article will help you! Today, we will look at the top 8 things to consider when buying an angle grinder.
1. Disc Size
The first thing to think about when choosing an angle grinder is the disc size, which might vary from 4-1/2 inch to 9 inches. This will affect the size of materials that you will be able to work with.
For the most common uses focusing on everyday projects, a 7-inch disc would work really well. However, larger disc sizes are better for those looking to make larger and deeper cuts.

The speed with which the discs revolve are determined by its size and the grinder’s power. This usually refers to the number of revolutions the disc makes per minute.
It is also something you might want to pay attention to, as the general options range from 5000 all the way to 10,000. Faster grinders are great for sanding and cutting. But remember to be careful as the spinning disc could cause injuries!
3. Motor Power
Consider the motor power that you want and need. The voltage, amp and wattage will differ from one model to the next.
Personally, I recommend angle grinders of 110 to 230 volts alternating current. In terms of wattage, try to look for one that is between 500 and 2,500 W. The stronger the grinder’s power, the more expensive and heavy-duty it is.
Equally important in an angle grinder is its weight, which has a noticeable impact on the performance. The weight generally depends on the type you are looking for and size often comes into play too. However, some grinders are naturally lighter too.
While it is important to find the perfect weight that you can work with easily, the most lightweight choice may not always be the best. In fact, you should consider getting a heavier one to handle tougher jobs and bigger projects.
The best kind of handle is adjustable so you can always get a comfortable angle to work with. I recommend angle grinders that let you use two hands to operate, especially for longer tasks.
Some handles even come with an anti-vibration feature, which will prevent fatigue in your arms when holding it. Plus, this also makes it easier for you to control the grinder accurately.
6. Safety Features
Safety features are crucial to ensure that you can work and operate the angle grinder as safely as possible. Try to look for a paddle switch, which is designed to cut off when one of your hands releases the switch. This is excellent to prevent injuries when working.
A slow start is great to gradually increase the speed without accidentally twisting it. Meanwhile, anti-kickback will automatically shut off the machine when the wheel is bound up. Lastly, a restart protection makes sure the grinder cannot operate when overheated.

7. Customer Reviews
When buying online, it’s wise to do some research on customer reviews, whether on online marketplaces or videos. This will give you a more comprehensive understanding of the product from the customer’s point of view, not just the official advertisement.
Besides, you can find out what other people like and dislike about it. Hopefully this will help you make a better decision!
Lastly, try to think about your budget and stick to it! An angle grinder can vary in terms of pricing, from basic beginner models to professional heavy-duty ones.
It may not be the best idea to splurge on the most expensive grinder, especially if you are only planning to use it occasionally. But remember that quality does matter in the end and getting a durable angle grinder will save you costs in the long run.
All in all, choosing the best angle grinder for your tool belt is simple if you know what to look for. Important factors include disc size, speed, power, weight, handle design and safety features.
Reading customer reviews helps too, as does planning a budget and sticking to it. Good luck!
