Abstract

A diamond abrasive tonehole file for leveling the tonehole rims of a musical instrument.

I claim:  
     
         1 . A tool for abrading the tonehole rim of a musical wind instrument comprising: 
 a first disk;    a diamond abrasive on at least one surface of said disc.    
     
     
         2 . The assembly of  claim 1  wherein the diamonds of said diamond abrasive are partially embedded into the surface of said disc.  
     
     
         3 . The assembly of  claim 1  wherein said diamond abrasive is a separate layer attached to said first disc.  
     
     
         4 . The assembly of  claim 1  wherein said first disc has a curved outer edge.  
     
     
         5 . The assembly of  claim 1  wherein said first disc has an angled outer edge.  
     
     
         6 . The assembly of  claim 1  wherein said first disc has a second disc attached to it; said second disc being a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole.  
     
     
         7 . A tool for abrading the tonehole rim of a musical wind instrument comprising: 
 a first disk and a second disc;    a diamond abrasive on said surface of said first disc;    said second disc being attachable to the first disc.    
     
     
         8 . The assembly of  claim 7  wherein said second disc is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole.  
     
     
         9 . The assembly of  claim 7  wherein said second disc has a diamond abrasive on at least one surface and is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole.  
     
     
         10 . The assembly of  claim 7  wherein said second disc has a diamond abrasive on at least one surface and is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole; 
 said diamond abrasive being a separate layer attached to said first and second discs.  
 
     
     
         11 . The assembly of  claim 7  wherein said second disc has a diamond abrasive on at least one surface and is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole; 
 said diamond abrasive being bonded directly to said first and second discs.  
 
     
     
         12 . The assembly of  claim 7  wherein said second disc has a diamond abrasive on at least one surface and is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole; 
 the diamonds of said diamond abrasive being partially embeded into the surface of said metal discs.  
 
     
     
         13 . The assembly of  claim 7  wherein said second disc has a diamond abrasive on at least one surface and is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole; 
 said first and second discs being metallic;  
 said diamond abrasive being a separate layer attached to said metal discs.  
 
     
     
         14 . The assembly of  claim 7  wherein said second disc has a diamond abrasive on at least one surface and is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole; 
 said first and second discs being metallic;  
 said diamond abrasive being bonded directly to said metal discs.  
 
     
     
         15 . The assembly of  claim 7  wherein said second disc has a diamond abrasive on at least one surface and is a locating disc for generally centering the first disc on said tonehole when the second disc is inserted into the tonehole; 
 said first and second discs being metallic;  
 the diamonds of said diamond abrasive being partially embeded into the surface of said metal discs.  
 
     
     
         16 . An abrasive disc for abrading the tonehole rim of a musical wind instrument comprising: 
 a flexible sheet with a first and second surface: 
 said first surface having a diamond abrasive;  
 said second surface having an adhesive for adhering to a disc.  
   
     
     
         17 . A tool for abrading the tonehole rim of a musical wind instrument comprising: 
 a first disk;    a cubic boron nitride abrasive on said surface.
