Pilot drill is for web clearance.
Get your best 1/4 drill with slow speed, lots of oil and pressure and drill a pilot.
If you stop just before the bottom (Set your stop) the almost through hole now will hold oil.
Works real good as otherwise you oil the floor.
Drill large bit with as mush pressure as the motor can take.
Keep the oil full
