I want to help you make the right decision when looking for the best cordless angle grinders. Therefore I have provided a buying guide and some recommendations below.

What Is an Angle Grinder?

An angle grinder, also called a disc grinder, is a tool used to polish or grind materials and surfaces. The tool has a disc-shaped blade attached to one side, rotating in a high-speed motion. Based on your requirements, the power and speed allow it to grind through materials or polish surfaces.

Additionally, the traditional angle grinder came with cords; however, the modern models have switched to batteries to increase user convenience.

Features to Consider When Buying an Angle Grinder

Tool manufacturing brands have surpassed all expectations with the recently produced models. Therefore, it can be understandably challenging to buy angle grinders that are the right fit for you. However, there is a way to make the decision quickly.

Following are the features you must focus on to ensure you buy the most suitable and affordable angle grinders.

1. Disc Size

Disc size is one of the essential parts of an angle grinder. It ranges between 4.5″ and 9″, with the higher diameters giving you the ability to cover a greater area. It is unlikely that you always need only small or large disc sizes, so it is much better to buy a flexible option.

Some angle grinders allow you to fit discs of different sizes, so you can always opt for them if you want to avoid getting two tools. Otherwise, getting an angle grinder with a smaller disc size also works since you can use it for both smaller and extensive tasks.

2. Rotation Speed

The disc’s rotation speed depends on the power—the greater the power, the greater the speed and the more significant the impact. Typically, angle grinders with higher power are more suitable for professional scale construction than simple DIY.

However, you don’t need to avoid them if you pursue this hobby more seriously.

3. Motor Power

The motor power of an angle grinder is determined by the voltage, wattage, and amperes required to run it. Higher wattages are known for providing greater motor power and speed to the grinder, but you must consider whether you need those features or not.

While high-powered grinders are perfect for bigger-scale tasks, they can negatively affect the efficacy of smaller-scale operations that require precision.

4. Size and Weight

Angle grinders come in several weights and sizes depending on their design, added features, and power. The higher-powered ones are usually bulkier due to the greater motor weight; however, several manufacturers now use alloys to reduce the impact.

Overall, you must select the size and weight that is most comfortable for you to use. Do not choose something that will become a burden because carelessness can cause serious injuries.

5. Safety Settings

As mentioned above, the angle grinder is a dangerous tool when handled carelessly. It can easily slice through flesh due to its sharp blade and high-speed rotation; therefore, selecting options with safety settings is better.

Angle grinders come with safety guards meant to cover the side facing outward or towards you. The purpose is only to allow the side actively working on an object to remain exposed to reduce risk.

The above guide will help you prioritize your preferences and select the best cordless angle grinders for yourself. However, it is also good to know what is popular in the market to set a suitable benchmark.
