How to Choose the Right Brushless Angle Grinder for Your Needs

Angle grinders have become an essential tool for many professionals and DIY enthusiasts alike. They are versatile and can be used for various tasks such as cutting, grinding, sanding, and polishing metal, concrete, and other materials. However, with the wide variety of angle grinders available in the market, choosing the right one for your needs can be a daunting task.

In this article, we will guide you through the essential factors to consider when selecting a brushless angle grinder that will suit your needs. We will also provide some tips on how to maintain your new angle grinder to keep it in good working condition.

1. Consider the power source

Angle grinders come in two power sources; electric and pneumatic. Electric angle grinders are more common and can be used in most applications. On the other hand, pneumatic angle grinders rely on compressed air and are typically used for heavy-duty tasks that require more power.

When choosing an angle grinder, consider its intended use. If you're planning on using it for light to medium-duty tasks, then an electric angle grinder would be ideal. However, for heavy-duty tasks, consider a pneumatic angle grinder.

2. Look out for the wheel size

The wheel size of an angle grinder determines its cutting, grinding, and sanding capacity. Angle grinders come in various wheel sizes ranging from four inches to nine inches. Smaller wheel sizes such as four and five inches are suitable for light-duty tasks such as sharpening and cutting small pipes and metal sheets. Larger wheel sizes such as seven to nine inches are ideal for heavy-duty tasks such as cutting concrete and metal bars.

When choosing an angle grinder, consider the size of the materials you'll be working with. A smaller wheel size may limit your ability to handle bigger materials.

3. Choose between corded and cordless models

Angle grinders come in two configurations, corded and cordless. Corded models offer a reliable power source meaning that they can run continuously without the need for recharging. On the other hand, cordless models are more convenient and portable but require frequent charging and can run out of power during use.

When choosing between corded and cordless models, consider the nature of the job and whether you'll have access to a power source. For jobs requiring a constant power supply, a corded angle grinder would be ideal. However, for jobs that require mobility, a cordless angle grinder would be the best option.

4. Pay attention to motor power

The motor power of an angle grinder determines its performance. Higher-powered motors can handle more demanding tasks and have a longer lifespan. When choosing an angle grinder, consider the job's nature and the materials you'll be working with. For example, a motor power of 11 amps would be sufficient for most medium-duty tasks such as cutting metal sheets. However, for more demanding tasks such as cutting concrete or metal bars, consider a higher motor power of at least 13 amps.

5. Look for safety features

Angle grinders can be dangerous when used improperly. Therefore, it's essential to look for models with safety features such as a safety lock switch or a safety guard. A safety lock switch ensures that the angle grinder doesn't turn on accidentally, while a safety guard prevents debris and sparks from hitting your face and body.

When choosing an angle grinder, look for models with these safety features to prevent accidents and injuries.

Maintaining Your Angle Grinder

To keep your angle grinder in good working condition, consider the following tips:

1. Clean your angle grinder after each use to prevent debris buildup and rust.

2. Store your angle grinder in a dry and cool place to prevent damage from moisture or heat.

3. Check and tighten the fastenings and screws before each use to prevent the machine's parts from coming loose.

4. Lubricate the moving parts regularly to prevent friction and prolong the machine's lifespan.

5. Replace the worn-out parts such as the discs and blades to prevent the machine from malfunctioning.

Conclusion

Choosing the right brushless angle grinder for your needs requires careful consideration of the motor power, wheel size, and safety features. Whether you're working on light or heavy-duty tasks, there's an angle grinder that will suit your needs. With proper maintenance, your angle grinder will last longer and provide you with reliable and efficient service.
