Method of making a saw blade

Abstract

A method of making a saw blade includes the step of providing a metallic blade body that defines a first side surface and a second side surface. The method further includes the step of providing the metallic material blade body with cutting teeth at an edge thereof. The method also includes the step of forming a plurality of discrete dimples on at least one of the side surfaces. The forming step includes the step of deforming the metallic blade body with pins on a die plate of a punch press so as to create a plurality of indentations in the side surface in which the dimples are formed.

What is claimed is:  
     
         1 . A method of making a saw blade, comprising the steps of: 
 providing a metallic blade body that defines a first side surface and a second side surface,    providing said metallic blade body with cutting teeth at an edge thereof; and    forming a plurality of discrete dimples on at least one of said side surfaces, said forming step including the step of deforming said metallic blade body with pins on a die plate of a punch press so as to create a plurality of indentations in said side surface in which said dimples are formed.    
     
     
         2 . The method of  claim 1 , further comprising the step of configuring said metallic blade body to form any one of the following group: a jig saw blade, a saber saw blade, a hack saw blade, a bow saw blade, a hand saw blade, a bone saw blade, a pruning saw blade, a keyhole saw blade, a miter saw blade, and a band saw blade.  
     
     
         3 . The method of  claim 1 , wherein said forming step includes the step of configuring each of said plurality of dimples to define a perimeter which is spaced apart from all edges of said metallic blade body.  
     
     
         4 . The method of  claim 3 , wherein said forming step further includes the step of configuring each of said plurality of dimples to include a ridge which is located at said perimeter.  
     
     
         5 . The method of  claim 4 , wherein said forming step further includes the step of configuring at least a portion of said ridge to extend above said side surface of said metallic blade body in which said dimples are formed.  
     
     
         6 . A method of making a saw blade, comprising the steps of: 
 providing a blade body which defines a side surface;    providing said blade body with cutting teeth; and    deforming said blade body with pins on a die plate of a punch press so as to create a plurality of dimples in said side surface.    
     
     
         7 . The method of  claim 6 , further comprising the step of configuring said blade body to form any one of the following group: a jig saw blade, a saber saw blade, a hack saw blade, a bow saw blade, a hand saw blade, a bone saw blade, a pruning saw blade, a keyhole saw blade, a miter saw blade, and a band saw blade.  
     
     
         8 . The method of  claim 6 , wherein said deforming step includes the step of configuring each of said plurality of dimples to define a perimeter which is spaced apart from all edges of said blade body.  
     
     
         9 . The method of  claim 8 , wherein said deforming step further includes the step of configuring each of said plurality of dimples to include a ridge which is located at said perimeter.  
     
     
         10 . The method of  claim 9 , wherein said deforming step further includes the step of configuring at least a portion of said ridge to extend above said side surface of said blade body.  
     
     
         11 . The method of  claim 6 , wherein said blade body is made of metal.  
     
     
         12 . A method of making a saw blade, comprising the steps of: 
 providing a metallic blade body which defines a first side surface and a second side surface; and    providing said metallic blade body with cutting teeth at an edge thereof; and    deforming both said first side surface and said second side surface with pins on a die plate of a punch press so as to create a plurality of dimples in each said first side surface and said second side surface.    
     
     
         13 . The method of  claim 12 , further comprising the step of configuring said metallic blade body to form any one of the following group: a jig saw blade, a saber saw blade, a hack saw blade, a bow saw blade, a hand saw blade, a bone saw blade, a pruning saw blade, a keyhole saw blade, a miter saw blade, and a band saw blade.  
     
     
         14 . The method of  claim 12 , wherein said deforming step includes the step of configuring each of said plurality of dimples to define a perimeter which is spaced apart from all edges of said metallic blade body.  
     
     
         15 . The method of  claim 14 , wherein said deforming step further includes the step of configuring each of said plurality of dimples to include a ridge which is located at said perimeter.  
     
     
         16 . The method of  claim 15 , wherein said deforming step further includes the step of configuring at least a portion of said ridge to extend above said side surface of said metallic blade body.
