Yes, for deep cuts that would be recommended. I’m sorry in advance if this leads you into yet another rabbit hole 
I would try the air blast approach first as it’s less messy, but this is personal preference. If you go the lubrication way, I see folks using either their air blast setup to inject a small amount of [something for lubrication, oil or water+alcohol mix] in the airflow, or a drip (and here I again find myself linking to @RichCournoyer famous WD40 drip system)
