Where Do You Need a Brushless Cordless Drill Driver
Cordless drill drivers are your essential power tools if you love doing home repair projects. The absence of cord in drills and drivers has helped make repair works easy, convenient and hassle-free. With so many advancements in their features, we have a variety of options of cordless drill drivers with better performance.
One such feature is that of brushless motor technology, bringing the brushless cordless drill driver to us. Brushless motor technology proves to improve the performance of cordless drill drivers, reduce maintenance, and extend its working life.
Parts and Features of a Brushless Cordless Driver
The motor of a brushed cordless drill driver mainly contains carbon rings, an armature, ring of magnets and a commutator. The motor of the brushless cordless drill driver has an absence of brushes and commutator. Instead of the commutator, it has a controller. The position of windings and magnets is reversed as they were in a brushed cordless drill driver.
The other parts of the motor are quite similar to that of a normal cordless drill driver. The windings of the stator can be arranged in a delta, star, or Y shape. The latest models of brushless cordless drill drivers do not have grooves and so work on lower inductance, which allows better speed and fewer ripples when working on the lower speed.
The magnets in the brushless drivers are on the conventional motor shaft whereas the copper windings of the armature fix around the shaft. The tool automatically adjusts according to the task drilling or driving. Let’ say if you have to drive screws in a Styrofoam, the controller senses the lack of resistance and pulls just the little charge from the battery. But if you start putting 3-inch screws into the heavy surface like mahogany it will accordingly adjust and draw more current.
Brushless cordless drill driver has very precise positioning. The motor can run-up to the speed of 50,000 rpm. The electronic module is very flexible and has a wider range of variations and the maintenance of torque.
With no friction between the rotor and stator, the working efficiency is greatly improved. It also allows the motor to operate without producing sparks even during intensive work.
Difference between Brush and Brushless Cordless Driver
You must know the differences between the two to know when you need to have a brushless cordless driver. The working of the two is basically the same, but they differ in structure, performance, and control.
The variants of the cordless brush driver are made up of carbon. But the brushless cordless driver uses magnets to generate power.
The commutation of a brushless drill driver runs electrically with the help of the controller, unlike the brushed drill, which runs mechanically.
What makes Brushless Cordless Drill Better than Brush Cordless Drill?
Brushless cordless drivers produce very little heat and friction. It has better adaptability and performance. The brushless units of cordless drill driver greatly reduce maintenance so there is no need of replacing the worn brushes.
Advantage of Brushless Cordless Drill Driver
There are several advantages of brushless cordless drill driver due to the use of brushless motor technology in it.
- The absence of brush avoids the problem of producing friction and overheating, thus no chances of breakdown after heavy usage.
- The maintenance of a brushless cordless drill driver is very easy and effortless — no need to remove and change the worn-out brushes.
- The service life is only related to the proper working of slip bearings of the brushless cordless drill driver.
- Brushless cordless drill driver also has a long-lasting battery life.
- The tool is more compact and lighter in weight and very portable.
- Vibration and noise are significantly less with a brushless cordless driver as compared to the regular cordless drill driver.
The Working of Brushless Cordless Drill Driver
Disadvantages of Regular Cordless Drill Driver
Although the regular brushed cordless drill drivers are reliable, inexpensive and have high torque ratio. But certain downsides make it less applicable for certain functions. We will see what those applications are but first have a look at minor shortcomings of brushed cordless drill driver:
- The friction and producing dust can wear out the components.
- The brushes require high maintenance. Cleaning and/or replacing of the brush is necessary.
- There is low heat dissipation capacity because of the rotor limitation, low maximum speed, high inertia and electromagnetic interference (EMI).
- With low heat dissipation, there are high chances of electrical arching in the brushes which can be very dangerous.
When do you need Brushless Cordless Drill Driver?
You can use a brushless cordless drill for all the regular and heavy drilling and driving work you do with a cordless drill driver. Brushless cordless drill driver can do everything a brushed tool can, but it does it significantly better. Here are the best uses of a brushless cordless drill driver:
- Drywall repair work
- Driving heavy and tough screws, bolt or nuts. Can effectively fix screws more than that are more than 2 inches thick
- drilling through the wall to expose wiring for electric work
- Drilling through heavy wood and log pieces for woodworks
- Drilling for making wood plugs
- Drilling through ceramic tiles
- Fixing and repairing floorboards and shelves
- Suitable for working on all kinds of heavy and light weighted surfaces
- Driving and joining metal panels
When do you not need a Brushless Cordless Driver
With great performance and adaptability of the brushless cordless driver, you might be tempted to maximize its applications. Sure, cordless drill driver works fast and better than your regular cordless drill driver, but that doesn’t mean you have to ditch your good old cordless drill driver.
Keep your cordless drill driver for all the regular home repair work where you don’t need to handle tough screws and heavy surfaces. Brushed cordless drill drivers require less or no external bits and components. So, they work well under restrictive conditions.
Although brushless cordless drill driver can work on a number of heavy surfaces, but they are not best for surfaces like concrete and masonry. You might be able to drill small precise holes on such surfaces but you won’t be able to make an intensive drill or drive nuts in them.
The brushless cordless drill driver has better performance, speed, and reduced maintenance than a brushed cordless drill driver. There is hardly any electrical hazard because of the absence of arching in its brushless technology motor. You can use a brushless cordless drill driver for a variety of applications you would use a cordless drill driver with greater efficiency.
But the brushless motor technology and adjustments in the tool make it expensive as compared to the brushed cordless drill driver.
