When sharpening a chain tooth with a chain grinder, if the top half of the top plate is sharp do I need to keep grinding until the gullet and the other half of the top plate is shiny steel?
A chaisaws tooth must be sharp on both the leading edge and the side at approximately 30 degrees. The raking tooth (the bit in front of the sharpened edge) must be filed to a depth of approximately 6 microns so as to allow the cutting edge to bite and create a chip that will not clog your saw. A raking tooth less than 6 microns will only allow dust to be created and your saw will over rev. A raking tooth too large will allow the saw to bight too deep making it stall and stick. You should always use a chainsaw file because using a grinder will burn the thin sharpened edge of the high alloy tooth

Your question does not make sense to me. Why not use a file to sharpen it? Much kinder and doesn't take long.
