Tongue & Groove 3/8" - 9

This 3/8" - 9 v-shaped knife mills a v-groove on the face side of a tongue & groove or shiplap joint pattern. The blades can mill a v-joint from zero to 5/8" wide based on how deep you set the radial movement on the top cutter-head on the machinery. The pointed knife gets centered on a 1-3/4" piece of high-speed steel or carbide, installed in a sixty-millimeter cutter head on an industrial moulder's first or second top horizontal machining station.
