Interesting thread! My dad would be so glad to discover this thread on drilling. He likes to build stuffs and we have a garage full of hardware tools. Someone asked about coolant. The thing about lubricating your drill bits, my dad would not recommend to spray oil on the table because he don't feel like getting oil all over the place with a WD40. So again worst case just have water. Water is easily dried I mean get a towel whatever. This will reduce friction.
