Frequently Asked Questions

What does the Ridgid Lifetime Service Agreement actually cover?

Register at ridgid.com within 90 days of purchase with your receipt. They'll replace the tool, batteries, and charger for defects and wear for the life of the tool at no cost. It doesn't cover abuse, but for a $129 saw, it's the best warranty in this segment.

How does the Ridgid circular saw compare to the DeWalt DCS573B?

The DeWalt DCS573B costs $30 more and performs similarly. The Ridgid R8656B has the warranty advantage. If you're already on one platform, stay there. If you're starting fresh, the Ridgid warranty tips the value equation.
