Frequently Asked Questions
Is the Ridgid grinder a good value?
At $89 with a paddle switch, electronic brake, and lifetime warranty, it's hard to beat on paper. The DeWalt DCG413 ($129) and Milwaukee 2780-20 ($149) have better motors and safety features, but the Ridgid covers the basics at a lower price.
Can I use larger discs on the R86047B?
It's rated for 4-1/2-inch discs. Some users fit 5-inch discs by removing the guard, which is dangerous and voids the warranty. Stick to 4-1/2-inch. If you need a larger disc, buy a grinder rated for it.
