Very similar to a chamfer cutting bit, the rounding over router bit is generally used to round off sharp and acute edges to leave a nice smooth and rounded one. The edge cutting bit is again commonly used in cabinet and furniture making for cutting and creating decorative edges, sometimes known as beads in cabinet and table tops, chair and table legs and many other different objects and surfaces.

Bullnose router bits for milling beaded edges with a single pass for beautiful stair treads, shelves or window sills. Due to this if the profiles are cut the same then essentially a rounded off joint will fit into a cove-cut joint.Where the routing over bit creates a nice rounded edge to an object, the cove bit does the opposite and cuts a concave profile into the object you are working on. So, I pushed through the cherry plywood making the 1/2 x 1/2 cut and it seemed both controllable and not an obvious drag on the router.

These radius grooving router bits are great for custom sign making, veining, lettering and edge work. If you are fairly keen on carpentry and joinery, the router is one of the best power tools you can have in your tools arsenal as it can be used for a huge variety of jobs from cutting hinge recesses, mitering worktops, trimming and shaping edges to cutting a whole variety of timber joints.Is it because a trim router and a 1/4" bit would just find that too hard, even if I did multiple passes?
