   Diamond wheels are available for a lot of things.  Yes, you can freehand   
   grind on a diamond wheel.  A buddy of mine sells tungsten grinding kits   
   for various grinders that include adapters, and a cheap diamond coated   
   wheel he buys in bulk from China.  He sells them to welders for shaping   
   tungsten electrodes.  I have one of his cheap wheels and I sometimes use   
   it to rough finish the edge on a tool before honing on a bench stone or   
   lapping stick.   
      
   I have a whole bucket (smallish) of broken and worn out carbide mills I   
   save for making specialty tools.  When I needed a special 7 degree   
   dovetail cutter to make a tool holder I ground one of an old carbide end   
   mill.  Okay.  I cheated.  I cut the 7 degree cutting edge on a tool and   
   cutter grinder with a diamond wheel, but other edges and clearances I   
   just ground freehand.
