Recently purchased a rotary hammer drill and some kind of grease or lubricate was at the bit end (opening) of my tool. I'm wondering what kind of grease is this?
I was watching a few videos and someone in the comment section claimed that not that many people know about the grease the needs to be applied often. I glanced over the manual to find out what the substance was and didn't see anything right away, so I figured I'd ask the question here.
What is this substance?
How often is someone supposed to apply this inside bit area or the dust shield?
Does it depend on tool brand?
