Brushless motors, although they are cordless, are in a league of their own in a wide range of cordless power tools. There is a line of brushless tools from all manufacturers. However, as a cautious buyer, you do not want to ensure that you have all the information, so you make the right decision.
So, what is this brushless technology and what does it mean for you? The first stage of constructing drills is installing a motor that has four different parts. These parts include magnets, carbon magnets, commutator, and armature. These parts work together to create a drilling motion that helps the machine run.
The brushless motors get their names because they do not use these parts. They do not have a commutator and the carbon brushes- thus the name. It ensures that you work more efficiently than the brushed drills used traditionally. They therefore also use less friction.

The main question you might have by now is what makes these brushless drills better? Other than the fact that they transition smoothly, these motors also sense things better. When it comes to working with different materials, you will notice a huge difference. Traditional drills treat all materials as though they are the same.
The brushless motors, however, handle all materials uniquely. They can differentiate between two different levels of hardness. They also have a circuit board to relay the signal from the battery to the armature. This circuit board is what makes all the difference. It helps the tool know how much power it needs to apply to carry out the task.
It uses the minimum amount of power to complete the job. These features make it efficient and reliable and also helps the battery last longer.
They are also strongest because their designs make them build up the device in the motor. That is something that brushed drills cannot achieve. It is why most contractors invest in them.
If they are so good, why doesn’t everyone get one? Well, their main issue is the price. They cost up to 30 percent more than traditional drills. That is the reason why not all woodworkers have one.

Here are a couple of features that will ensure that you get the best tool for the job. First, you need to find out what type you need
Before you think about looking at the different models on the market, consider the kind of drill you need. The type you need will vary depending on the types of jobs you do. There are three main categories to select from: general use, heavy-duty and light-duty.
These are according to their chuck sizes. The chuck size determines work the drill can do. These give you the upper limit of the shank size of the bits that each drill accommodates. It also tracks closely to a drill’s capability and power. The more critical the chuck, the more powerful the drill is and the more massive the work it can do.
These are great because they have batteries that range between 18 and 24 volts. They, therefore, have the power to drive larger fasteners and drill bigger holes through thicker materials. They have ½ inch chucks that can accept most drill bits. Thus, you can work on wood and stricter materials like concrete and bricks.
However, their capabilities make them bulky and expensive. So, before you buy, please make sure you test it with the battery in place to see how it feels.
General Use Drills
These are the most popular drills because 3/8 chuck models serve them. They often need a 12-volt battery and are lighter. They are best when used to bore holes into wood. The battery life is not great, so you have to keep one battery charging as you work and swap them.
Light Duty Drills
These are perfect for the small jobs around the homes like assembling furniture and drilling into drywall. The batteries range from 12 to 20 volts. They have motors, but the engines are small, so they do not spin with general use. However, they have a limited ¼ inch socket that only accepts similarly sized hex bits. They are therefore great to have around the home.
There are three basic types of cordless drills. Here are a few that you must choose from:
Drill or Driver
It is the most common type of drill that most people use. Its primary function is to drive screws and drill holes. They also come with a cord that keeps them tethered to a power source. Drivers are light duty and perfect for most homes and general use.
Right Angle Drill
The right-angle drills get built to allow you to find the right angle through the cutting down on the size of the drill in an unusual way. They let you go through tight places and have great torque and power than most of the more massive drills. It is great for specialized tasks, and they have become quite common in the recent years.
The impact driver is the best for removing nuts off tires in a few seconds. The impact drivers come in different size and are perfect for busting frozen bolts and driving screws off wheels.
This drill is perfect for masonry and other sturdy materials. They are an industrial class. Their functionality and performance depend on the strength of the motor.
Power and Performance
The power and performance vary depending on the torque and horsepower. If you want to sink a screw into a thick stock, you need a drill that is powerful. If you do not do any tough jobs, you may go for one that does not have too much horsepower.
The thing about drills is that you do not need to have a cookie-cutter speed. The best ones allow you to switch between two or more speed. It, therefore, will enable you to work on different materials as you want. Variable speed drills have a trigger lock that allows you to select the different speeds available.
Some allow you to choose the specific drilling speed while others only give you two settings- high and low speeds.
Ease of Use and Comfort
You always want the tools you buy to be easy to use and comfortable. You must be able to hold the drill in your hand for a long time if you have a massive project to work. You may want to choose lightweight drills so you can work with them for a long time. Bigger motors and metallic parts mean that the tool will be heavy and therefore awkward to use.
Batteries and Chargers
The drill cannot work if it does not have a great motor. The cordless batteries will vary so it will be difficult to peg down a specific range. You need to ensure that the battery can last for a couple of hours without running out. It will ensure that you can at least accomplish something before it goes out.
You also need to ensure that you have both regular chargers and quick chargers. In case you are in the middle of a project, and the battery runs out. You will quickly get the battery charged in minutes. Therefore, your project will not get stopped for hours as you wait for the battery to charge. Alternatively, consider getting several batteries for your drill.
How to Change a Drill Bit
Start by inserting the nub of the chuck key into the hole and side of the drill chuck. Always ensure that you have the correct chuck key for the drill.
Then rotate the chuck key to the left which will loosen the drill chuck. Often, you might need to use a little force here but do not use too much that you damage them.
Lastly, remove the drill bit by just pulling it out. Replace it with a new drill bit and insert the chuck key into the drill chuck and rotate that key to the right to tighten the drill bit and ensure it works perfectly. This tightening may be different for different types of drills. On the keyless models, you have to give the trigger a few short squeezes.
Can you Use a Hammer Drill as a Regular Drill? Are They the Same?
They use a forward thrusting action to work. As the drill-bit spins, it vibrates back and forth rapidly as it goes through the materials you are working. So, is a hammer drill the same as a regular drill? No. however, it is easy for you to use the hammer drill as a substitute for the regular drill.
First, hammer drills have three methods that alter how they function. The hammer mode has a straight impact action as a jackhammer. There is also the drill mode that works like a regular drill. Therefore, you can use this mode to get it to work as a regular drill.
Regular models are cheaper than hammer drills, but you can buy the hammer drill, and you will have a two in one drill for less. However, the choice you make will depend on the projects you do.
Q: What are the types of drill bits available in the market?
A: There are various types of drill bits available for both industrial and residential use. The universal drill bits are significant because they can work on any material from plastic to concrete. The universal drill bits have several variants like a hole saw, twist bits and step bits. You need to choose the perfect bit for the type of material you are working on and the kind of screws you are using.
Q: How do I remove the batteries?
A: Push the buttons and pull it forward. However, with most of these tools, you have to buy the battery separately.
Q: Can the drill bits from all the drills compare in this review interchange?
A: Yes, these are the same drill bits that can work for different drills. The chucks are fully adjustable and can accommodate most diameters.
With the right tools, you can finish faster and more effectively. Choosing the right drill does not have to be tough. With this guide, you will get the best tool for your money. You will also get to enjoy a device that is comfortable and easy to use.
