What Size Angle Grinder Should I Buy – Expert Tips


What size should I buy? Most do-it-yourselfers and craftsmen have a million-dollar demand. To answer this question it is important to note that the size of an angle grinder depends on many factors.

In addition, the dimensions of an angle grinder are determined by the grinding wheel and not by the overall length of the tool. We understand that this decision can be quite difficult to make given the abundance of information already available on the Internet.

In this article, however, we make it easier for you in this decision-making process. Let’s look at the factors that need to be taken into account.

The nature of the task can vary from simple to medium to difficult. The different angle grinders are designed for different applications. Most masters think that the size of the grinder depends on the length of the tool, but this is not always the case. Large angle grinders are generally longer to accommodate large discs.

In addition, most craftsmen prefer 4.5-inch angle grinders because they are lighter, have a smaller frame and are well suited for domestic projects. They are also best suited for light and medium-duty tasks. Therefore a 4.5 inch disc is best suited for such a grinder, while a 7 inch angle grinder works best with 7 inch discs, etc.

The larger the angle grinder, the larger the disc and therefore more suitable for heavy-duty applications. For example, if you’re trying to cut a wooden beam with a 4.5-inch wheel, that’s certainly a routine job, but with 7-inch wheels it’s easy. Nine-inch shredders were popular and preferred hard work, but they were banned because they caused too many accidents.

Type and size of material

Most angle grinders can cut through wood, although a smaller angle grinder is difficult to use on thicker wood. For other materials such as stone or concrete, small angle grinders may not be the best choice.

This is because these materials are strong and thick. For example, a 5-inch grinder with a 5-inch disc cannot cut thick concrete or wood because only half the diameter can be penetrated.

Therefore, the best angle grinders for thick materials such as concrete and stone are those with 7 inch discs and larger. She’ll cut a little deeper.

It is known that small plates rotate faster than large ones. Due to their smaller diameter, and therefore smaller circumferential diameter, they can reach about 11,000 revolutions per minute. This means that they can be used for polishing and cutting surfaces.

The disadvantage of using small motors is that they often overheat at such high speeds. It is recommended to choose an angle grinder with an adjustable speed to have some control.

Of course, the speed of an angle grinder goes hand in hand with the power of the motor. This means that while a 5-inch angle grinder can run faster, a 7-inch angle grinder with a more powerful motor can run faster, if not faster, than a smaller disc with a smaller spare motor.

And last but not least, it’s about your level of knowledge. For beginners it is better and safer to start with a smaller grinder, because then you can always improve and update yourself.

For professionals, on the other hand, they can use larger machines, such as 7-inch angle grinders, because they can support more advanced features. In fact, large grinders can be so powerful that they can be operated with both hands.

Regardless of the size of the angle grinder, the safety rules must be observed first and foremost. Always wear protective clothing to prevent accidents when grinding, polishing, grinding or cutting surfaces. It is clear that the choice of angle grinder is not that complicated.

Once you understand these factors, you can choose the angle grinder that best suits your needs and the size of the grinder.
