lithium grease I think. You can get stuff rated for worm drive saws and it wouldn’t surprise me if it’s fine for other applications as well.

for skil saws use skil 80111 saw lubricant it’s like the consistency of honey,other tools check what they recommend or you could be paying big tool repair costs,trust me i used to repair tools years ago and had many skil saws with the worm gears totally destroyed by using the wrong lubricant.

white lithium grease is my go-to for most anything. Its waterproof, easy to apply and a little goes a long way.

Most all bearings (with a ZZ suffix) are sealed and don’t need lube. But worm gears and such like a dab now and then.

I use white lithium grease or synthetic wheel bearing grease for that type of stuff if enclosed .i always have both in the garage. I just try to match up what was originally in there. Of course some things like worm drive saws may be completely different, like the kind with oil etc.

My 2 go to(note the valvoline grease is labeled NLGI #2 grade lithium complex EP grease

I was a tech working primarily with Milwaukee and Senco but serviced and repaired all other major brands as well. Milwaukee seemed to have a different grease for nearly every model, some of it was expensive. Now my go to is Valvoline waterproof bearing grease with lots of molybdenum. I’ve used it in everything from circular saws to Sawzalls to jig saw. It is not suited for worm drive applications, they need the correct oil or the brass worm gear will be destroyed.

back in the eighties we kept getting nail guns coming in that wouldn’t fire properly,opened them up and it looked like someone had poured a strawberry milk shake in there.we find out they were using trans mission fluid,seems another tool repair company was telling guys to use it.i guess they wanted more business-lol.

I had a few of those too. Not sure who might suggest that but if the o-rings aren’t compatible with ATF, they won’t last long. Most in pneumatic tools aren’t.

Always use caution in “mixing” grease lubricants. The are made with a variety of what they cal “soap” bases which is the thickener for the lubrication elements and constitutes 80+% by volume of the product.. Common soaps are, aluminum, calcium, sodium, and lithium. They do not mix so if you don’t know what you have be sure to clean the old grease out thoroughly before adding more.

White lithium grease is what I usually use on my tools.

On any of my machines that are “gear and chain driven” I use the old style “axle grease” (been around since before I was born), but on “delicate gears and ball bearings, such as fishing reels, etc., I use the white lithium grease. On nail guns, etc. I use the recommended oil that comes with each one. Some 3-n-1 oil on other things like table saw motors.
