So I got the Canadian Tire brand step drill bit today and I knew the hole I wanted was 7/8, so I thought I would drill the hole.
I did a good punch mark, but the step drill would wander, so I tried drilling a pilot hole to allow the step drill to get started. Four broken or dull bits later, I barely made a mark in the stainless steel, but it was enough for the step bit to get started.
I put oil on it, pause about three times in between steps so it did not get too hot, but I knew each time that I added the oil, the area was hot. I made it to the 7/8 step and stopped right away. I dont get the bulkhead until tomorrow and want to check to see how it fits before doing anything else.
Although the edge that I could see was a nice clean hole, I was surprised to see the inside was not a clean hole at all.

Not sure if I have to go a little farther with the step drill and it will clean it off, but I know I cannot put the bulkhead on with the metal shards sticking out. Not positive on how to remove them without making a mess. Also not sure how it happened other than the bit did not have a good enough cutting edge for stainless steel.
