Astro Pneumatic Tool 498K 0.498" Shank"THOR" Air Hammer/Riveter.

I am not one to write reviews very often, so hopefully this review makes for a good impression.So far I am thoroughly impressed with this air hammer. Previously I owned the standard barrel length Astro 4980. That air hammer kicks ass....puts SnapOn, Matco, IR, you name it, to shame. But then my 4980 stopped working....just blew out air without any impacting.Then I got this bad boy. And ohhhhh boy. I never thought I'd be so happy with an air hammer in my career as an auto technician. If you want something to move, this hammer will do it. And the greatest thing I've noticed so far compared to my last is this one actually has a decent degree of trigger control! The 4980 is either on or off, no in-between.This one has some feather control. But let's all be honest here, if you're looking at getting this bad boy, you probably already own a decent 401 shank hammer....for obvious reasons stick to that for general tasks.But if what you're working on requires a bit of ass, grab this guy, you too will be impressed.Today I pushed out two lower ball joints on a rusted out f150....each ball joint pushed out in less than 8 seconds. Previously last week I pushed out two press bearings....7 seconds for each of them.Wear your eye protection (squint guards wont work), and make sure you have some extra stock in 498 bits. I have not broken any yet but have heard this guy can break them.This is an early review since I have not owned this tool for very long. I will provide an update assuming anything changes.

This Bad Mamma Jamma will either break it loose or break you for trying. For those of us in the rust belt living that salt life, this baby fully unlocks your vehicles true weight reduction feature, hammering loose rust you never knew existed. I don't know that the regular 4980 would have been able to beat these up the same way the 498k Destroyed them. And let me tell you having both, this Big Girl makes you put on your Big Boy Pants before going to town.

Cannot wait to destroy everything with it this will put my snap on one to shame

Did not work out of the box. Just blows air out the exhaust.

It was worth the wait.
