There are advantages and disadvantages to both brushed and brushless power tools, and the choice of which is better depends on the specific application scenario and needs.

The advantages of brushed power tools are that they are more affordable due to their relatively simple structure and lower manufacturing costs. However, they also have some disadvantages, such as friction and wear due to the physical contact between the brushes and commutator, which can shorten the life of the motor, as well as generating a certain amount of noise and electromagnetic interference. In addition, the efficiency of brushed motors is relatively low, and more energy is lost during the electrical energy conversion process.

Brushless power tools, on the other hand, adopt advanced electronic commutation technology, which eliminates the traditional brushes and commutator, thus reducing friction and wear and prolonging service life. At the same time, brushless motors are more efficient, can better realize the conversion of electric energy, and have superior speed regulation performance, with a wider speed range and higher speed accuracy. These advantages give brushless power tools a greater advantage in applications that require high performance, high precision and long life. However, the manufacturing cost of brushless power tools is relatively high, but with the continuous development and maturity of the technology, its cost is gradually decreasing.

Therefore, when choosing a power tool, it should be weighed against specific application scenarios and needs. If you are more sensitive to cost and do not have high performance requirements, you can choose brushed power tools; if you need high-performance, high-precision and long-life power tools, it is recommended to choose brushless power tools.
