RIDGID introduces the R86047 18V 4-1/2 in. Paddle Switch Angle Grinder Kit. RIDGID’S brushless motor technology delivers maximum performance and longer runtime. The powerful brushless motor in this grinder delivers up to 25% more power than its predecessor model (R86042B), with 9,000 RPM.

Using an electronic break mechanism, the wheel quickly stops rotating as the user lets go of the paddle switch.

The R86047 Grinder includes the grinder, a type 27 grinding wheel, guard, auxiliary handle, R840040 18V 4.0 Ah MAX Output Battery, R86093 18V Charger and Operator's Manual.
