A rag damp with water or lube (depending on material being drilled) is a creative aid for hole saw.
Seeing someone dispense lube at the drill point, it's worthwhile pointing out that works, better yet to apply higher on the bit, allowing gravity to feed the cut for a greater duration. Lube formulas can work at nearly invisible amount of film, compared to coolants at higher rates.
At brass tacks, "cutting lube" is rather a misnomer, it's more of a film with minimal surface tension; certainly bearings won't think of it as lubricant.
That's a good tip with applying it higher and it makes sense. I'll have to harp on my daughter the next time when do I video like this (she squeezed the oil for me!). All kidding aside, thanks for that.Quote:

Evening neighbor; without going off too dramatic, certain young'uns will bear the load of stabilizing our civilization, if things continue as they are.
Comfort around equipment is pivotal, to any degree of success.
Personal experience tells such females will be front row center.
Back to subject, thread cutting oil never wears out. Just watch a plumber; there is a catch pan under the die in a pipe machine. Recycling before it was even named.
It's a helluva stabilization that's needed, too. I've taught my kids to do 2 years trades first before going after anything else, that way they'll always have a job in any city in any country of the world when plan 'b' inevitably fails. What a strange world we've charted into...
We see (along with select others) things exactly alike.
