Default Countersinking the Spar

Quick question: I am in the process of countersinking the spar for the plate nuts. Should I be using a drill bit lubricant such as Boelube or nothing at all while doing so? Thank you ahead of time for the guidance!

Default Just me

I only lubricated drills when used in steel or when called out in directions

No need for any lubricant. Keep that countersink cage under control and enjoy drilling.

Where is N666BK?
