brushed or brushless drill: choosing the right tool?
Imagine a tool that moves faster than a hummingbird’s wings, with the power to drive a screw through thick hardwood effortlessly—the modern power drill. Since its invention, the power drill has transformed countless industries and DIY projects. Whether you're assembling furniture or building a house, drills have become essential for their versatility, power, and convenience. When choosing a drill, one of the most important decisions is whether to go for a brushed or brushless model. Both have their strengths, but understanding the differences will help you make the best choice.
In this blog, BISON offers a detailed comparison between brushed and brushless drills, highlighting their key differences, advantages, and disadvantages. By learning about each type, you’ll be better equipped to choose the right tool that fits your needs and preferences.
Now let's dive into how brushed and brushless drills work. The names directly refer to the motors they use—brushed motors and brushless motors. All other features, such as power, torque, ease of use, and maintenance, are largely determined by the motor type.
Understanding Brushed Drills
Brushed motors are among the simplest DC motors available. Before brushless technology emerged, brushed drills were the go-to choice for many professionals and DIYers. So, how do they function? The key lies in the interaction between brushes and a commutator inside the motor.
The motor consists of a rotating armature (rotor) wrapped with copper wire coils, and a set of stationary magnets surrounding it. When electricity flows in, the carbon brushes transfer current to the commutator, which is made of metal segments. As the commutator spins, the brushes touch different segments, changing the direction of the current in the coils. This creates a magnetic field that interacts with the fixed magnets, generating rotational force to turn the drill.
Brushed drills are simple and cost-effective to produce, making them affordable and easy to repair. However, their design also brings some limitations, which we'll explore next.
Understanding Brushless Drills
Although brushed drills dominated the market for years, technological advancements led to the development of brushless drills. These tools eliminate the need for physical brushes and a commutator, offering improved performance and efficiency.
At the core of a brushless drill is an electronic controller, acting like a smart brain. It regulates the flow of current to the motor's windings, eliminating the need for mechanical brushes. Instead, the rotor contains permanent magnets, while the stator has coils. When the stator is energized, it creates a magnetic field that attracts the rotor's magnets, causing it to rotate and power the drill.
Brushless vs. Brushed Drills: A Comparison
Efficiency and Power
Brushed drills are generally less powerful due to energy loss from friction and heat caused by the brushes. In contrast, brushless drills avoid these losses entirely. They use electronic circuits to control the current, resulting in higher efficiency, longer battery life, and greater durability. Brushless drills are also lighter, quieter, and can reach extremely high RPMs—often over 50,000.
Maintenance and Longevity
Brushed drills require regular maintenance because the carbon brushes wear down over time, leading to downtime and added costs. The friction between brushes and the commutator also causes heat and wear, shortening the motor’s lifespan.
Brushless drills, on the other hand, are nearly maintenance-free, requiring only occasional cleaning. While electronics can be expensive to fix, brushless motors typically last much longer, making them ideal for frequent or heavy use.
Cost Analysis
Brushed drills are usually more affordable, while brushless models tend to be pricier upfront. However, their longer lifespan and lower maintenance costs often make them more economical in the long run.
Application Suitability
For light tasks like hanging pictures or assembling furniture, a brushed drill may be sufficient. But for heavy-duty jobs involving concrete or repeated drilling, a brushless drill is the better choice. Professionals in construction, carpentry, and other demanding fields often rely on brushless tools for their reliability and performance.
BISON’s Future Projections
As technology advances and production costs decrease, we expect more consumers to switch to brushless drills. The price gap is narrowing, making them more accessible. Additionally, manufacturers like BISON are continuously improving brushless tools with features like smart technology, app connectivity, and better battery life. BISON believes that understanding brushless drills now will prepare you for the future of the power tool market.
Conclusion
In summary, brushed drills are great for DIYers or those on a budget, while brushless drills are ideal for professionals or users with demanding projects. BISON hopes this comparison helps you make an informed decision based on your specific needs.

FAQs
Do brushless drills last longer than brushed ones?
Yes, brushless drills typically last much longer. Brushed drills have a shorter lifespan due to wear on the carbon brushes, averaging 1,000 to 3,000 hours. Brushless models, without brushes, can operate for tens of thousands of hours.
What are brushes?
Brushes are essential components in many power tools, including drills, jackhammers, and grinders. Made of carbon, they connect the motor’s stationary part to the rotating rotor, ensuring smooth power transmission and spark-free operation.
Is a brushless motor faster than a brushed one?
Yes, brushless motors are generally faster and more efficient. They offer higher torque, better speed control, and improved heat dissipation, making them ideal for demanding applications.
Stainless steel rods have broad application prospects and are widely used in hardware kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, building decoration, nuclear power, aerospace, military and other industries! Equipment used in seawater, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; food industry, coastal facilities, ropes, CD rods, bolts, nuts.
According to the production process, stainless steel rods can be divided into three types: hot-rolled, forged and cold-drawn. The specifications of hot-rolled stainless steel round bars are 5.5-250 mm. Among them: small stainless steel round bars of 5.5-25 mm are mostly supplied in bundles of straight bars, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used for the manufacture of mechanical parts or seamless Steel Pipe billets.
This alloy is ideal for applications in highly corrosive environments due to its low carbon content, which reduces the chances of intergranular corrosion when exposed to high temperatures or welded joints.
