Tool inserts

Abstract

A unit including a plurality of tool inserts, such as used in saw blades for use in woodworking. Each insert defines a working region and is adapted to be secured to a tool to present that region with a predetermined orientation. A body defines a plurality of discrete zones, each zone having an insert located therein such that the orientation of the working portion at each insert in the zone is the same.

1 . A unit comprises: 
 a plurality of tool inserts, each insert defining a working region and being adapted to be secured to a tool to present that region with a predetermined orientation; and    a body defining a plurality of discrete zones, each zone having an insert located therein such that the orientation of the working portion of each insert in the zones is the same.    
     
     
         2 . A unit according to  claim 1  wherein the body is elongate in form and the zones are defined along the length of the body.  
     
     
         3 . A unit according  claim 1  wherein the body takes the form of a tape.  
     
     
         4 . A unit according to  claim 1  wherein the zones are pockets or recesses in the body into which the inserts are placed.  
     
     
         5 . A unit according to  claim 1  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.  
     
     
         6 . A unit according  claim 2  wherein the body takes the form of a tape.  
     
     
         7 . A unit according to  claim 2  wherein the zones are pockets or recesses in the body into which the inserts are placed.  
     
     
         8 . A unit according to  claim 3  wherein the zones are pockets or recesses in the body into which the inserts are placed.  
     
     
         9 . A unit according to  claim 6  wherein the zones are pockets or recesses in the body into which the inserts are placed.  
     
     
         10 . A unit according to  claim 2  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.  
     
     
         11 . A unit according to  claim 3  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.  
     
     
         12 . A unit according to  claim 4  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.  
     
     
         13 . A unit according to  claim 6  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.  
     
     
         14 . A unit according to  claim 7  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.  
     
     
         15 . A unit according to  claim 8  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.  
     
     
         16 . A unit according to  claim 9  wherein the tool inserts are for use with saw blades, each insert comprising a PCD layer bonded to a carbide backing, with the PCD layer defining the working region.
