How to Select Different R Sizes of Roundover Router Bits for Furniture Making

Learn how to pick proper R radius sizes of roundover router bits

Different R radius specifications of roundover router bits create totally different visual results. Small R sizes make subtle gentle curves, which are perfect for thin boards and delicate indoor cabinet panels. Larger R sizes produce bold rounded edges, commonly applied to table tops, solid wood crafts and decorative moldings. Most suppliers provide roundover router bit sets containing multiple common R sizes, so woodworkers can switch quickly for different projects. Bits built with carbide inserts for router bits keep stable cutting precision even in mass production. When selecting, consider workpiece thickness first. Too large an R bit may cut through thin panels and damage workpieces. Matching R size with product design can help you achieve ideal rounded edges without extra polishing work after milling.
