What's the current hotness as far as an air hammer, these days. I need/want a new one, and curious what ya'll would recommend.
What do you need to do with it?
I used my big nasty Mac one to unscrew trans pan bolts the other night after the 8mm heads wouldn’t come out with a 6.5mm twist socketThis. Big nasty is nice for whacking on wheel bearings. Not going to use it to unscrew rotten exhaust hardware.

Needs: to bang on stuff? Don’t really know how to answer this.
My current POS got used today with a pointed bit to love-tap the rear end of my Crown Vic driveline and unseat it from the pinion.
It was then used to drift the u-joints out of said driveline, unsuccessfully - just seemed anemic, power-wise, and since it’s a no-name that I forget where I got it, I figured it was time to buy something decent and reliable.
I obviously don’t use an air hammer all that often, so I don’t need the best of the best, but figured I’d query here to see what’s good.
TTC seems to really like the IR 119MAX which seems priced nicely (about the same as the HF Chief Professional Long Barrel), so maybe I’ll look that way.
The Astro “Bug Nasty” is a .498 shank instead of the “standard” .401 shank - dunno if that means .401 stuff is incompatible with the .498 gun, or just that .498 stuff won’t fit a .401 gun?
Correct, .498 and .401 are different sizes. You can however use an adapter which in my experience works just fine, though you will occasionally break .401 bits using them in a big bore .498 gun. Bit selection is very limited and expensive in .498 so i suggest having an adapter on hand if you want to go for a big boy.Needs: to bang on stuff? Don’t really know how to answer this.

Roto hammer in hammer only mode.Why does no one have a cordless "air" hammer?
It seems physically possible and I want one. I realize it might end up with a little bulk and less power. I don't care - if they can give me at least short-barrel power, I'm in.
Ok, that's fair - but surely they could make something smaller than that if it doesn't need to spin.Roto hammer in hammer only mode.
The only non-spinning one is the MX fuel breaker and that is exactly the opposite of what you are asking for.Ok, that's fair - but surely they could make something smaller than that if it doesn't need to spin.
Many have asked the same question, It’s a far more complex design concept (air hammer is literally a slug in a tube with two holes in it) since you need to convert rotary motion to linear, have it reciprocate very fast and and hit very hard. It’s been done with rotary hammers of course but they’re absolutely enormous compared to an air hammer and quite expensive. Hard to imagine how you could do it in a much smaller package with decent striking force.Why does no one have a cordless "air" hammer?

Why not a piston-like design? E.g. have the electric motor spin the "crank" and move a piston back and forth rapidly, contacting the chisel at the end of each stroke. I imagine something cordless drill-sized.Many have asked the same question, It’s a far more complex design concept (air hammer is literally a slug in a tube with two holes in it) since you need to convert rotary motion to linear, have it reciprocate very fast and and hit very hard.

only way i could imagine is cutting out the motor and doing it like a gauss cannon/railgun, but I’m not sure those could be made to reciprocate quickly, be energy efficient enough to run on battery or cost effective
That actually is how rotary hammers work already, the biggest thing really is the fact that you need that AND a beefy motor to turn it, a cordless drill sized motor cannot provide that kind of force and you need to add a robust piston mechanism on top of that, so essentially you’re looking at XL drill + piston mechanism + batteryWhy not a piston-like design?

I have the Chief buy Harbor Freight. It is the same one as Matco. The Chief out performed the Snap On and is one third the price. It is the full size and when you pull the trigger you had better hang on. Long barrel 4 inch stroke. Model CH 401LB Cost is now $139.

Funny you mention that, that’s the exact same model I have

It is the similar to the MAC Tools air hammer, not the Matco.I have the Chief buy Harbor Freight. It is the same one as Matco.
I have the 119’s predecessor the 118. I couldn’t ask for better. There are more powerful (like the big nasty) but a good 119 is going to be very powerful for a .401 shank air hammer while still being about as controllable as an air hammer can get. I use mine a lot for removing stripped out level check plugs, cutting off hardware, walking out stripped out torx bolts and so on but it also does some brute force work pretty well…I’ve used it to loosen up seized hydraulic cylinder glands.
