<p>A saw blade has teeth grouped with varying shapes or other characteristics, such as composition. Each tooth has a root and a head separated by a transition region forming a neck. The roots may be oversize in relation to apertures or slots preformed in the strip, so that the teeth displace and deform the material of the strip, as they are forced into the position shown. They may then be fixed in position by brazing.</p> |
