It’s no secret that drills are one of the most popular tools in any workshop. They’re versatile, portable, and perfect for a wide range of applications.
But when it comes time to choose a drill, there’s more to consider than just power and capacity. You also need to decide between brushed and brushless motors. In this article, we’ll take a comprehensive look at both types of drill motors and help you decide which is right for you.
What is a brushed drill and how does it work?
A brushed drill is a type of electric drill that uses brushless DC motors. These motors are more efficient than traditional brushed DC motors and offer superior torque and speed control.
A brushed drill uses carbon brushes to transfer electricity to the spinning armature, which creates the motion that turns the drill bit. The commutator switches the current direction as the armature spins so that the magnetic field created by the current always pushes against the armature in the same direction.
This system is simple and reliable, but it has a few downsides. First, the brushes create friction and heat, which can wear down the armature and reduce the drill’s power over time. Second, the commutator can also create sparks that can cause dust and debris to accumulate on the armature, which can eventually lead to a loss of power.
A brushed drill is typically used for lower-torque applications, such as drilling holes in wood or metal. They are also often used in cordless applications, as the lack of a brushless motor makes them more lightweight and easier to handle.
Brushed drill spec
Here are some of the specs you should look for in a brushed drill:
- Amperage: the higher the amperage, the more power the drill will have. Look for a drill with at least 12 amps.
- Speed: the speed of the drill is measured in revolutions per minute (RPM). A higher RPM will allow you to drill through materials faster. Look for a drill with an RPM of at least 2000.
- Weight: heavier drills will be more difficult to use for extended periods of time, so if you plan on doing a lot of drilling, look for a lighter drill.
What is a brushless drill and how does it work?
A brushless drill is a type of power drill that uses an electric motor to rotate the drill bit. The motor is powered by a battery, and there are no physical brushes that contact the spinning parts of the motor. This design results in a more efficient motor that produces less heat and requires less maintenance.
A brushless drill is perfect for when you need more power and precision from your drill. With no brushes to wear out, a brushless motor will give you a longer lifespan and more consistent torque.
Brushless drill spec
Here are some of the specs you should look for in a brushless drill:
- Torque: this is a measure of the amount of force that the drill can apply to a screw or bolt. Higher torque values mean that the drill can handle tougher applications.
- Speed: this is the number of rotations per minute (RPM) that the drill can achieve. Higher speeds are better for drilling through materials like wood and plastic, while lower speeds are better for driving screws.
- Amperage: the higher the amperage, the more power the drill will have. Look for a brushless drill with at least a three-amp motor.
Difference between brushed and brushless drills
Here are the key differences between brushed and brushless drill motors:
- As brushed drill motors have commutators that transfer power to the brushes, this makes them less efficient because some of the power is lost in the transfer. Brushless drill motors have stators that transfer power to the rotor and this makes them more efficient because there’s no loss in power during the transfer.
- Brushed drill motors have more moving parts, so they require more maintenance. Brushless drill motors have fewer moving parts, so they require less maintenance.
- Brushed drill motors are cheaper. Brushless drill motors are more expensive.
So, which type of motor is right for you?
When it comes to choosing between a brushless or brushed drill, there are a few things you need to take into consideration.
- The most important factor is the type of work you’ll be doing with the drill. If you’re only going to be using it for light drilling around the house, then a brushed drill will probably suffice. However, if you’re looking to do some serious work, then a brushless drill is the way to go.
- Another thing to keep in mind is the price. Brushless drills tend to be more expensive than brushed ones, but they also offer more power and durability. If you’re on a budget, then a brushed drill may be the better option. However, if you’re willing to spend a little extra, then a brushless drill is definitely the way to go.
- Finally, it’s important to consider the battery life when choosing between a brushless or brushed drill. Brushless drills tend to have longer battery life since they don’t have brushes that need to be replaced. However, they are also more expensive. If you’re looking for the best of both worlds, then a brushless drill is probably the right choice for you.
Now that you know the difference between brushless and brushed drills, it’s time to make a decision. Consider your needs and budget when making your decision, and you’ll be sure to choose the right drill for you.
