摘要： A circular saw blade has block-like tooth tip inserts of hard metal, secured at circumferentially spaced intervals to the peripheral portion of a disc-like blade body having opposite flat side surfaces. The gullet in front of each insert, conventionally present in such a blade, is spanned in the circumferential direction, at least to a substantial extent, by a fixed thin wall, which can comprise a reduced thickness portion of the blade body, so that each gullet is thus defined by a sidewardly and radially outwardly opening cavity in a side surface of the blade, and the blade has a near-circular periphery. At the circumferentially rearward and radially inward portions of each cavity its edges are substantially bevelled to facilitate flow of cuttings out of the cavity.
摘要翻译：环形锯片具有硬质金属的块状齿尖插入物，其周向间隔地固定到具有相对平坦侧表面的圆盘状刀片体的周边部分。通常存在于这种叶片中的每个插入件前面的齿槽至少在一个固定的薄壁上至少在一个大的程度上沿着圆周方向跨越，该固定的薄壁可以包括叶片本体的厚度减小的部分，因此，齿形物由叶片的侧表面中的侧向和径向向外的开口腔限定，并且叶片具有近圆形的周边。在每个空腔的周向后部和径向向内的部分，其边缘基本上是倾斜的，以便于将切屑流出空腔。
