This small cordless angle grinder requires no brush changes and offers longer motor life. The DEWALT cordless grinder provides a high level of protection. Its brake stops the wheel in 2 seconds or less. The anti-kickback engages maximum force to stop the wheel in a pinch, stall, or bind-up to reduce kickback. The grinder will also shut off during these events to further protect the user. Battery and charger are sold separately.
