Features

  • Brushless motor of the angle grinder requires no brush changes.
  • DEWALT grinder's brake stops wheel in 2 seconds or less on average
  • Kickback Brake engages when a pinch, stall, or bind-up event is sensed and the electronic brake engages with maximum force to quickly stop the wheel, reduce the movement of the metal grinder and shut the grinder off.
  • Features E-Switch Protection - When the ON/OFF trigger switch has a no-volt release function. In the event of a power outage or other unexpected shut down, the trigger switch will need to be cycled (turned off and then on) to restart tool.
  • Two stage trigger requires two actions to activate tool.

Description

This brushless small cordless angle grinder requires no time changing brushes, and offers a longer motor life. DEWALT cordless grinder offers a high level of protection. Its break stops the wheel in 2 seconds or less. The Kickback Break engages maximum force to stop the wheel when there is a pinch, stall, or bind- up to reduce kickback. The grinder will also shut off in those events to further protect the user. Battery and charger are sold separately.

  • Great tool. Love it. The guard is easy to adjust for convenience
Style: 20V BL 4.5IN Angle Grinder
Huge upgrade from my hobo freight corded one that is 20 years old. It has plenty of power and the battery lasts longer than I expected.

  • DeWalt quality
Style: 20V 4.5IN Grinder

  • Great Dewalt Tool
Style: 20V 4.5IN Grinder
One of my most used Dewalt tools. I bought it for cutting bricks for a new patio but it has so many more uses. The arbor/nut with include allen wrench makes it easy to change out cutting wheels. Doesn't seem to use battery power excessively either.

  • Good grinder
Style: 20V BL 4.5IN Angle Grinder
Came in it's original box everything seems legit but it did come with an allen wrench that clearly doesn't go to the grinder. Did not come with the grinder wrench to tighten the disks down.
