    head porting tool

    I'm doing some port matching & clean up on the head of my 78 gs 750. I need suggestions on what tool to use. I don't have an air compressor to run a 1/4" di-grinder, a drill turns too slow to use my 1/4"cutting head & my dremel only accepts 1/8 cutting heads. If my dremel would accept the larger 1/4 cutting it might work.
    Any suggestions for an electric tool to use?

      Thanks,

      I'm only going to do some smoothing & port matching but,I'll keep that in mind. Any ideas for an electric 1/4" grinder?

        I use Eastwood sandpaper rolls and taper's in my electric drill. Yes it's slow but then you don't cause much damage if it touch'es something it's not suppose too. I also use gloves cause she's going to get hot.

          Doesn't it take forever to get the job done??
          There must be something out there that is like a air powered die grinder except powered by electricity.
