Carbide Tipped 12-1/2″ Thin Knife Set (11/16″ × 1/8″)

Description

The TN632CT is a 12-1/2″ × 11/16″ × 1/8″ carbide-tipped HSS thin knife set for jointers and planers with 12-1/2-inch cutting width. Thin knife sets are precision-ground to the exact machine knife length, matching the cutterhead slot dimension of specific machine models with 12-1/2-inch capacity. The 11/16 knife width (height) and 1/8 thickness are the head slot specifications — confirm both dimensions match the installed cutterhead before ordering. Sold as a set of matched knives for the full head complement required by the machine. Carbide-tipped construction extends edge life in abrasive manufactured boards, hardwood, and high-volume softwood production where standard HSS edge intervals are too short — carbide tips require diamond grinding equipment for resharpening. After installation, set knives to the correct height above the cutterhead using a setting jig or dial indicator for consistent, flat surface results. Thin knife geometry suits jointer and thicknesser heads designed for this knife section; do not substitute for corrugated-back or smooth-back bar-length stock without confirming head compatibility.
