A spoilboard bit is a large, flat-bottomed router bit used primarily with CNC machines to level or surface the spoilboard, which is the sacrificial surface on the machine bed. It ensures the spoilboard is perfectly flat and parallel to the cutting plane, providing accurate and consistent cuts for workpieces. A quality Carbide Flattening bit will give you the best outcome and years of great service , just remember to give it a cleaning every so often .
