Well It Finally Happened

My hv pump was bogging a 3/8 drill out, needed to go to a 1/2 drill.
I was only using 5w-30 oil.
Lol yeah we started with my battery operated Dewalt drill. When that wasn't enough we switched to a right angle drill that was close by and the finally to a 1/2 inch hammer drill, that go results. I am using 5/30 as well.
