Circular saw blade for woodworking having a stepped thickness variation and inner and outer radial broaching-cutting edges

摘要

Circular saw blade having outer broaching-cutting edges and inner broaching-cutting edges, in which the outer thickness increases on both sides uniformly on the step diameter to the inner thickness, the step diameter lying approximately at the centre between the tooth-base diameter and the innermost broaching-cutting edge diameter, and the outer broaching-cutting edges and the inner broaching-cutting edges being approximately the same in length as the radial width of these annular thickness regions.
