Modifying an endmill.

Who needs a tool and cutter grinder when you've got steady hands and a Dremel!

I needed to cut more than 1/2" off the end of this cutter so I could get closer to the cut and reduce chatter, however I don't really have anything meant for the job... What I did in the end was to get a diamond cutoff wheel for the Dremel, put the tool in the spindle and run it backwards at low speed, then ever so carefully cut the end off with the cutoff wheel running in the opposite direction.

Seems to have worked surprisingly well!
