Investigating the Cost Difference Between Brushed and Brushless Angle Grinders

Investigating the Cost Difference Between Brushed and Brushless Angle Grinders

Angle grinders are an essential tool in many industries, but choosing the right one can be a challenge. One of the key decisions that you have to make is whether to go for a brushed or brushless angle grinder. Of course, the cost is always a consideration, but is it worth paying extra for a brushless model? This article will explore the cost difference between brushed and brushless angle grinders, as well as the advantages and disadvantages of each type.

What are Brushed and Brushless Angle Grinders?

Before we dive into the cost difference between the two types of angle grinders, let us first define what they are. Brushed angle grinders are powered by a motor that uses carbon brushes to transfer electrical power from the stationary part of the motor to the rotating part. As the motor runs, the carbon brushes wear down and need to be replaced periodically.

On the other hand, brushless angle grinders use a different type of motor that does not require carbon brushes. Instead, they rely on a controller that sends electrical pulses to the motor windings, causing the tool to rotate. Without brushes, there is less friction and wear, resulting in a longer lifespan for the motor.

Cost Comparison Between Brushed and Brushless Angle Grinders

Brushless angle grinders are generally more expensive than their brushed counterparts. The cost difference can vary depending on several factors, including the brand, the power output, and other features. In general, you can expect to pay about 20-40% more for a brushless angle grinder. For example, a basic 4.5-inch brushed angle grinder can cost around $30-$50, while a similar brushless model can be priced anywhere from $80 to $150.

Advantages of Brushless Angle Grinders

Although the initial cost of a brushless angle grinder may be higher, there are several advantages that make them a worthwhile investment in the long run. Here are some of the benefits of using a brushless angle grinder:

1. Longer Lifespan: Brushless motors have fewer parts that are prone to wear and tear, making them more durable and longer-lasting than brushed motors.

2. More Efficient: Brushless motors are more efficient than brushed motors because there is no friction caused by brushes. This means that they require less power to operate, resulting in longer battery life and less heat production.

3. More Power: Brushless motors have a higher power-to-weight ratio than brushed motors, meaning that you can get more power out of a smaller motor. This makes brushless angle grinders ideal for heavy-duty applications.

4. Quieter: Brushless motors operate at a lower noise level than brushed motors, making them more comfortable to use for extended periods.

Disadvantages of Brushless Angle Grinders

Despite the many advantages of brushless angle grinders, there are also some disadvantages that you should be aware of:

1. Higher Cost: Brushless angle grinders are more expensive than brushed angle grinders, which can be a significant drawback for some users.

2. Incompatibility with Older Batteries: If you have an older battery or charger, it may not be compatible with a brushless angle grinder. This means that you may have to invest in a new battery and charger.

3. More Complex: Brushless motors are more complex than brushed motors, which means that they require more advanced controls. This can lead to higher repair costs if something goes wrong.

Conclusion

Deciding between a brushed and brushless angle grinder is not a straightforward task, as both types have their advantages and disadvantages. While brushless angle grinders are generally more expensive, they provide superior performance, efficiency, and durability in the long run. On the other hand, brushed angle grinders are cheaper and suitable for light to medium-duty applications. Ultimately, the choice comes down to your needs, preferences, and budget.
