Abstract
The present invention relates to a circular saw blade comprising a first annular saw blade having a plurality of teeth projecting radially from the periphery thereof and a second circular saw blade having a plurality of teeth projecting radially from the periphery thereof. The first blade has a greater diameter and a smaller thickness than the second blade and the teeth on the first blade are angularly set so as to partially extend into the cutting plane of the second blade. The blades are mounted coaxially adjacent to one another such that when used to cut through a workpiece, the first blade makes a fast rough cut and the second blade follows partially within the path of the first blade and provides a smooth, finished cut.
Claims16
A saw blade comprising:
- a first saw blade having a plurality of teeth projecting radially from a periphery thereof;
- a second saw blade having a plurality of teeth projecting radially from a periphery thereof, said second saw blade having a greater number of teeth than the first saw blade;
- the first saw blade having a greater diameter and smaller thickness than the second saw blade, the teeth of the first saw blade being larger than the teeth of the second saw blade;
- and
- means for coaxially mounting the first and second saw blades together.
A saw blade comprising:
- first blade means for cutting a first path through a material comprising a first circular saw blade;
- second blade means thicker than the first blade means and mounted adjacent the first blade means for cutting a second path through the material, said second blade means comprising a second circular saw blade;
- first teeth mounted on the periphery of the first blade means, said teeth being set at an angle with respect to the plane of the first blade means such that said first teeth extend partially into the plane of the second blade means;
- second teeth on the periphery of the second blade means, said second teeth being recessed from the first teeth and being smaller than the first teeth for making a smoother cut than the first teeth;
- whereby the first teeth are arranged to cut away a partial path in the material for the second blade means.
