I have a K & M which I've recently fitted with the 50 cal heat sink handle.
That aside, I've been able to turn continuous cuts using a practice an American correspondent uses. I put the cutter in water between cuts while I'm mounting a new case on the holder. I've found that a .30 cal Berger bullet box is about perfect size to catch the adjustment knob on the box edge while dunking the mandrel & cutter in water, the level of which I adjust to suit. I lube the mandrel once per run with Imperial sizing wax (OK I don't use all that much so haven't bought the newer label yet) & the water does the job from there on. Apart from it being a lube, it keeps the mandrel from expanding with heat & washes off those nuisance chips most of the time.
I dry it off with toweling after & give it a good squirt of my favourite dewatering fluid (that is whatever one is closest to the bench).

I am taking a quick break from a neck turning session as well. Yes, the handle in a small container of water. I just use plain water to rest it in, just a quick flick when you pick it up and it is dry enough, no messy coolant or anything to deal with. The carbide mandrels are better than the steel ones, less friction and heat build up. I just wish the expander mandrels were half a thou bigger.
