摘要

The holes in the sawblade (1) for securing the reinforcing ring (2) are cylindrical and arranged in one or two segments (6, 7). The distances between the external diameter of the ring and the outer screw hole segment and between the internal diameter of the ring and the inner screw hole segment are both 6-10 mm. The sawblade contains two different size diameter holes (5) for adapter pins arranged in unequal segments (8, 9) and on unequal diameter axes (10, 11), or these holes are arranged in a single segment and on unequal diameter axes, and have different diameters. Spacer discs or rings (3) are provided between the sawblade and at least one reinforcing ring.
