ABSTRACT:
A finger joint cutting tool includes unitary finger joint cutter bits. Each cutter bit has a unitary body to provide several integrally formed finger cutting teeth for finger jointing wood materials. Preferably the body is formed by an electrical discharge machine (EDM) process to provide the cutting teeth without any pinchpoints between teeth. The cutter bit therefore does not include several separate stacked knives to provide the cutting teeth. The finger joint cutting tool includes a head having a predetermined axis of rotation. The head has a plurality of locating surfaces spaced radially about the head which receive the finger joint cutter bits at a constant diameter. Each cutter bit is unitary and has a planar cutting face capable of being sharpened. The cutting face includes a plurality cutting teeth having linear fingering edges extending radially between adjacent base and tip edges. Each of the base edges are located at the same radius relative to the axis. Likewise, each of the tip edges are located at the same radius relative to the axis. Each of the fingering edges are aligned at the same angle relative to the axis. The tips and the bases have the same axial width whereby the dimensions of the teeth are substantially equivalent to the dimensions of gaps defined between adjacent teeth.
