A brushed drill has a traditional motor design with carbon brushes that deliver electricity to the rotating armature. These brushes make physical contact with the commutator, which causes friction and wear over time.

Brushless drills offer improved power and performance compared to brushed drills. They are more efficient due to the absence of brushes, resulting in less energy loss and longer runtime. The electronic control system in brushless drills also allows for better speed control, torque adjustment, and overall precision.

Brushed drills are generally less efficient than brushless drills and may deliver slightly lower power output. Over time, the brushes wear down, resulting in decreased performance. However, brushed drills can still handle most drilling and driving tasks effectively.

Brushless drills offer improved power and performance compared to brushed drills. They are more efficient due to the absence of brushes, resulting in less energy loss and longer runtime. The electronic control system in brushless drills also allows for better speed control, torque adjustment, and overall precision.

Since brushed drills are less efficient, they tend to drain batteries faster. This means you may need to recharge or replace the batteries more frequently, especially when tackling demanding tasks.

Brushless drills are known for their longer runtime and extended battery life. The efficiency of the motor reduces power consumption, allowing the battery to last longer. This feature is particularly beneficial for heavy users or those working on extended projects.

Brushed drills require more maintenance due to the presence of carbon brushes that wear down over time. Periodically, you will need to replace the brushes to maintain optimal performance. Additionally, the brushes generate more heat, potentially leading to motor overheating.

Brushless drills require less maintenance since there are no brushes to replace. The absence of brushes also reduces the risk of overheating. Consequently, brushless drills have a longer lifespan and are generally more durable.

Brushed drills are typically less expensive than their brushless counterparts. If you have a limited budget or don't anticipate heavy or prolonged use, a brushed drill can be a cost-effective choice.

Brushless drills tend to be more expensive upfront due to their advanced technology and superior performance. However, the increased efficiency and longer lifespan often make them a worthwhile investment, especially for professionals or frequent users.
