1/4 Round Corner Router Bits
1/4 round corner router bits create small smooth roundovers on shelves, cabinet parts, table edges, furniture components and decorative trim. They are useful when you want to soften sharp corners without making the profile look heavy.
Select the bit by radius, shank size, bearing style and cutting diameter. A bearing-guided roundover bit is practical for consistent edges, while fence-guided setups can help with repeated router table work.
For clean results, make a light finishing pass and watch the feed direction near end grain to reduce tear-out.
