Cut channels for pipes or cables in one single pass using CMT's ball end bits. Reduce the stress on the bits by cutting a first groove with a straight bit. The bit design gives you a wide flat bottom cut and the longer shank allows for deeper detailing. Bit is equipped with 2 Hi-Density carbide-tipped cutting edges for long-lasting cutting performance, features anti-kickback design to control the depth of cut and 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).
