Keep every cut accurate with a dead-flat spoilboard. Our CNC surfacing bits — also called spoilboard cutters, fly cutters and slab flatteners — true your wasteboard back to your gantry so depth stays consistent edge to edge. Choose insert-style cutters like the Amana RC-2255 for production shops, or solid carbide-tipped bits like the Onsrud 91-000 and Amana 45525 for a clean finish. New to surfacing? Read our step-by-step spoilboard surfacing guide for bit selection, speeds and feeds. In-stock items ship the same day from our Canadian warehouse.
