DeWalt launches brushless-motor impact driver and other tools

Stressing its commitment to innovation and system expansion, DeWalt announced this week the launch of more than a dozen cordless and corded tools as well as some accessories. Topping the list is a new impact driver in the 20-Volt Max line, but this one sports DeWalt’s first brushless motor. It will be on the market in April, selling for $279 with 1.5-amp-hour battery packs and $349 for 3-Ah packs.

This new impact driver comes out less than a year after DeWalt debuted the 20V Max line—which included an impact driver and several drill/drivers—featuring standard carbon-brush motors. The brushless motor powers the tool more efficiently, creating less heat and friction, and resulting in a 57% increase in battery run time compared to the 20V Max driver with carbon-brush motor. With a brushless motor, energy is transferred from the armature to the drive train electronically, whereas with the other system that energy transfers through the brushes by rubbing directly on the armature.
