We call this tool a bowl and tray bit but you can get lots of work from it, for example rout beautiful raised sign lettering, unique boxes, or lots of other specialty or craft items. The round corner of the bit shapes the inner radius while the sides and bottom create the smooth flat surfaces. Bit is equipped with 2 Hi-Density carbide-tipped cutting edges for long-lasting cutting performance PTFE-coating to prevent pitch and resin build-ups. CMT orange bits have been rated the #1 overall router bits compared to other brands (Wood Magazine).
