Abstract
A quick change cutting link of a saw chain for cutting wood comprises a base member adapted to be pivotally connected to other links of the saw chain. The base member comprises a seat surface. A cutting member comprising a 'V' notch releasably engages the seat surface of the base member. Attached to the 'V' notch is a carbide tip, including a cutting edge. The carbide tip is accurately placed in the “V” notch by mating with a small piece of metal in the “V” notch. The carbide tip is then sinterbrazed to the cutting member. The cutting member and seat surface may also comprise an inverted L-shaped protrusion and the other includes an inverted L-shaped recess for receiving the inverted L-shaped protrusion. The inverted L-shaped protrusion and recess may be designed so as to form a wedge.
