The RIDGID R86047 is an 18V cordless 4-1/2 in. angle grinder with a brushless motor spinning at 9,000 RPM. RIDGID rates it at up to 25% more power than the older R86042B, and it adds an electronic brake that stops the wheel quickly when you release the paddle. Tool-free wheel and guard changes cut downtime, and it runs on any RIDGID 18V battery. It suits homeowners and trade users already on the RIDGID 18V platform who want cordless grinding and cutting without a cord; corded grinders still deliver more sustained power for heavy continuous work.
