The Freud variable corner round bit saves you time by rounding both edges on a board in one pass, rather than using standard rounding over bits that require two passes. Works with stock from 7/16" to 1-/1/4" thick, simply add or subtract spacers between the cutters to adjust to match your stock thickness. Use with hand-held or table-mounted routers to cut hardwood, softwood, plywood or composites.
