Makita DHR243RTJ cordless combi hammer

In direct current electric motors, at the point where the electric current is supplied to their rotating part, two brushes (also called brushes or carbon brushes) are used. Over time, due to friction, the brushes wear out and need to be replaced. For this reason, in recent years, brushless electric motors have been developed, which greatly surpass a brushed motor.

What is a brushless motor?

In direct current electric motors, at the point where the electric current is supplied to their rotating part, two brushes (also called brushes or carbon brushes) are used. Over time, due to friction, the brushes wear out and need to be replaced. For this reason, in recent years, brushless electric motors have been developed, which greatly surpass a brushed motor.

Advantages

Due to the absence of brushes, they exhibit minimal mechanical wear and the need for maintenance is minimized.
They have higher efficiency
No noise and sparks are caused by friction
They achieve very high speeds

The package includes

2 batteries BL1850B (18V/5.0Ah Li-ion)
Quick charger
Makpac case
Quick chuck
