I dull down the bit slightly.. that way it wont try to bite.. when the bite bites is when they break.. also.. iron cuts easy thats why they tend to bite

9/32" drill and some WD-40. Don't know the rpm, just use what felt right. It drills pretty easy.

if you use oil or lube, it tends to make the cuttings into lapping compound and makes the hole oversized, do it dry if the hole is dimension critical

Don't make a bigger project out of this than it really is. I drilled mine and shoved 2 pieces of house water line in it, peened it with a rounded of scrap lifter (then I found the old peening tool that came in my Ed Hamburgers kit I bought years ago), drill your oiling hoes, enlarge the ones you want bigger, drill and tap the front to block off the other side, and wash,wash,wash to flush everything out. I may have skipped a step or two but the book walks you thru nicely and I still refer to it every time I do one as one missed step could get VERY expensive. Just DON"T forget to drill the holes thru the tube after you have it installed. Trial fit your lifters to make sure the tube has been peened sufficiently.
