Abstract:
A unitary finger joint cutter bit for mounting to a finger joint cutter head for rotation about an axis, comprising:a unitary body having leading and trailing ends, the body having a mounting surface, an outer surface and side surfaces extending transversely between leading and trailing ends, the side surfaces extending transversely between the mounting surface and the outer surface, the body having a plurality of teeth formed into the outer surface intersecting the leading end along a continuous cutting edge without pinch points, the leading end intersecting the mounting surface at an obtuse angle and being planar such that it is capable of being sharpened, the cutting edge comprising fingering edges extending linearly between adjacent base and tip edges, the tip edges being aligned with each other, the base edges being aligned with each other, each of the fingering edges having the same angle relative to the mounting surface, the tip edges and the base edges having the same axial width whereby the dimensions of the teeth are substantially equivalent to the dimensions of gaps defined between adjacent teeth.
