Do You Need This SUPERIOR DRILL TECHNOLOGY?! (Brush Vs. Brushless Tools--WHAT'S THE DIFFERENCE?!)

What do tool brand upgrades like Dewalt XR and Milwaukee FUEL really mean? And why is there such a huge difference in cost for some of the cordless power tools? This short video from The Honest Carpenter will explain the newest revolution in the cordless tool market!

The big differences in cost and performance in cordless drills and other cordless power tools often comes down to BRUSH TOOLS VS. BRUSHLESS TOOLS.

Brushless technology used to only exist in industrial machinery. But lately, it has been showing up in our handheld, cordless power tools, especially drills.

Both Brush (or "Brushed") and Brushless refer to the engineering of the tool motor.

Brush tools have long been the go-to for small tool motors. Brush tools use a rotary action to transfer their power.

Brushes are little carbon blocks housed in the motor. They're held in contact with a commutator, which spins between the brushes.

Power from the battery or electrical cord flows through a switch when the trigger is pulled. A wire carries it to the brushes, which transfer it into the commutator. The commutator sends it to a dense coil of copper wires on the rotor--the Armature.

The Armature takes on an electromagnetic charge, which pushes against a group of stationary magnets surrounding it in the brush motor. A series of positively and negatively charged magnets force the armature to spin, thereby turning the rotor, which turns the drill head (or other brush tool blade or bit).

Unfortunately, brushes wear down over time due to their contact with the commutator. This can cause sparking, and overheating, which drastically reduces the efficiency of the brush tool.

BRUSHLESS TOOLS did away with the brushes and commutator!

Instead, they have large magnets attached directly to the rotor. The armature is stationary and surrounds the magnets. A little circuit board on the armature acts like a brain, directing current and polarity through the armature. This causes the magnets and rotor to turn, thereby powering the tool.

In brushless tools, there is very little contact between parts. So, you get no friction, no overheating, and no worn-out brushes!

Brushless tools and drills can produce 20-30% more torque and speed. And, they can last for thousands of hours of usage.

Dewalt XR is Dewalt's brushless tool line.

Milwaukee FUEL is a line of HIGHLY EFFICIENT brushless tools, though their M18 line also has some brushless tools.

Makita LXT refers to great lithium-ion batteries shared by many Makita cordless tools, both brush tools and brushless.
