The covetto form - produced by the cove bit - is one of the classic building blocks for many moulding profiles. Use it alone or in combination with beads and fillets. Use the cove to detail the edges of casework, doors and drawers, posts and columns. The cove also makes up one-half of the rule joint used on drop-leaf table, the other half is the corner round.

For best results with a large radius cutter, make a preliminary cut with a smaller radius bit or chamfer the work piece to reduce the amount of stock to be removed in the finish pass. This will produce a smoother finish and prolong tool life. The largest diameter its must be run at reduce speed. Use in a handheld or table-mounted router.
