Abstract

A saw blade incorporates an integrated cant angle. The saw blade includes a cutting portion having a toothed edge and opposite edge. The toothed edge defines a cutting plane. A shank portion extends from the cutting portion and is laterally offset from the opposite edge of the cutting portion defining a step thereat. The shank includes an end portion including a mounting edge, the mounting edge and step define a mounting plane which is angularly offset from the cutting plane.

Claims

1. A saw blade comprising:

a body adapted for reciprocating engagement with a tool, said body including a cutting portion and a shank portion along a longitudinal axis thereof, said cutting portion having a cutting edge on a first side and a back edge on a second side opposite said first side, said shank portion having a first edge generally extending from said cutting edge and being laterally offset outwardly relative to said cutting edge, a second edge generally extending from said back edge, and a rear mounting edge generally connecting said first and second edges, said first edge extending substantially linearly from said cutting edge to said rear mounting edge, a first portion of said second edge proximate said back edge, said first portion being substantially parallel to said back edge and laterally offset from said back edge such that said first portion is positioned inward of said back edge toward said shank first edge, a stepped portion formed between said first portion and said back edge, a second portion of said second edge extending inwardly from said first portion and being angled with respect to said first portion to define an angularly disposed edge section proximate said rear mounting edge, said second portion extending substantially along said longitudinal axis and disposed at an angle relative to said first portion toward a line collinear with said shank first edge, and said angularly disposed edge section generally defining a reciprocating axis of said saw blade.

2. The saw blade of claim 1, wherein said shank portion includes an aperture therethrough.

3. The saw blade of claim 2, wherein said aperture includes a flat edge proximate said rear mounting edge.

4. The saw blade of claim 3, wherein said flat edge is generally perpendicular to said angularly disposed edge section.

5. The saw blade of claim 1, wherein said angle is an acute angle.

6. The saw blade of claim 5, wherein said angle is between 2 and 6 degrees.

7. The saw blade of claim 1, wherein said rear mounting edge is generally perpendicular to said angularly disposed edge section.

8. A saw blade and clamping system comprising:

a support structure including a pair of lateral walls and a base portion extending between said lateral walls, a majority of each of said lateral walls being generally parallel to one another; and

a saw blade having a body adapted for reciprocating engagement with said support structure, said body including a cutting portion and a shank portion along a longitudinal axis thereof, said cutting portion having a cutting edge on a first side and a back edge on a second side opposite said first side, said shank portion having a first edge generally extending from said cutting edge and being laterally offset outwardly relative to said cutting edge, a second edge generally extending from said back edge, and a rear mounting edge generally connecting said first and second edges, said first edge extending substantially linearly from said cutting edge to said rear mounting edge, said second edge proximate said back edge, a first portion of said second edge being substantially parallel to said back edge and laterally offset from said back edge such that said first portion of said second edge is positioned inward of said back edge toward said shank first edge, a stepped portion formed between said first portion of said second edge and said back edge, a second portion of said second edge extending inwardly from said first portion and being angled with respect to said first portion to define an angularly disposed edge section proximate said rear mounting edge, said second portion extending substantially along said longitudinal axis and disposed at an angle relative to said first portion toward a line collinear with said shank first edge, and said angularly disposed edge section adapted to engage one of said lateral walls of said support structure, said angularly disposed edge section generally defining a reciprocating axis of said saw blade.

9. The system of claim 8, wherein said base portion includes a stop thereon and said rear mounting edge of said saw blade is disposed against said stop.

10. The system of claim 8, wherein said shank portion includes an aperture therethrough.

11. The system of claim 10, wherein said aperture includes a flat edge proximate said rear mounting edge.

12. The system of claim 11, wherein said flat edge is generally perpendicular to said angularly disposed edge section.

13. The system of claim 8, wherein said angle is an acute angle.

14. The system of claim 13, wherein said angle is between 2 and 6 degrees.

15. A saw blade comprising:

a body adapted for reciprocating engagement with a tool, said body including a cutting portion and a shank portion along a longitudinal axis thereof, said cutting portion having a cutting edge on a first side and a back edge on a second side opposite said first side, said shank portion including an aperture therethrough and having a first edge generally extending from said cutting edge, a second edge generally extending from said back edge, and a rear mounting edge generally connecting said first and second edges, a first portion of said second edge proximate said back edge, said first portion being substantially parallel to said back edge and laterally offset from said back edge such that said first portion is positioned inward of said back edge toward said shank first edge, a stepped portion formed between said first portion and said back edge, a second portion of said second edge extending inwardly from said first portion and being angled with respect to said first portion to define an angularly disposed edge section proximate said rear mounting edge, said second portion extending substantially along said longitudinal axis and disposed at an angle relative to said first portion toward a line collinear with said shank first edge, said angularly disposed edge section generally defining a reciprocating axis of said saw blade, and said aperture in said shank portion including a generally flat edge proximate said rear mounting edge, said flat edge being generally perpendicular to said angularly disposed edge section.
