I've drilled more holes in my Bayou Classic than I care to admit to. So I thought that I was a kettle drilling expert. I brought home a 1/2 barrel to make a keggle out of and so far I am getting no where fast. After 30 minutes I have a definite dimple created, but nothing even close to resembling a pilot hole. I have titanium bits, is there something else I should be using? And I tried to find cutting oil at all the local hardware stores and none of them carried any. Will any oil work? Also, how do you use the oil?
