Editing Swaging (section)

=== Saw blade teeth ===
In [[sawmill]]s, a swage is used to flare large [[bandsaw]] or circle saw teeth, which increases the width of the cut, called the [[wikt:kerf|kerf]]. A clamp attaches a mandrel and die to the tooth and the eccentric die is rotated, swaging the tip. A much earlier version of the same operation used a hardened, shaped swage die and a hand held hammer. Saw teeth formed in this way are sometimes referred to as being "set". A finishing operation, shaping, cold works the points on the tooth sides to flats. It might be considered as a side swage. This slightly reduces the tooth width but increases the operating time between "fittings". Swaging is a major advance over filing as the operation is faster, more precise and greatly extends the working life of a saw.
