Thin Knife Set — 8 x 3/4 x 1/8 Carbide Tipped

Description

The TN616CT is a 8″ × 3/4″ × 1/8″ carbide-tipped HSS thin knife set for jointers and planers with 8-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 8-inch capacity. The 3/4 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.
