Astro Tools 401K 0.401" "Thor Super Duty Long Barrel Air Hammer/Riveter

Brilliant tool, usual good Astro quality. I've only used it a few times so far but it's as good as I all the reviews say.

For a good long time I suffered with a cheap air hammer from princess auto. I finally decided to get this beast when my old one wouldn't do the job anymore. When I first used it, I was so disappointed because it felt very weak. If you read the instructions it tells you that it doesn't give you the grunt until it been cycled about 8 times. It for sure has some grunt to it now. I even used it to help chip my concrete floor when installing my lift. Astro air tools never disappoint and this is no exception. It's not the big nasty version, but it for sure deserves the name Thor

This air hammer is worth it's weight in gold. I purchased it because of the Torque Test Channel on YouTube and it has proved itself multiple times in just a few days of use. I stayed away from air hammers because of their price and I've been getting along fine using my 4 pound sledge and pickle fork set. After watching several videos and other technicians recommending getting an air hammer I purchased the 401K Thor. The 498 Thor was tempting, but for regular automotive work you truly cannot beat the price of this tool. It is a big air hammer but is definitely extremely well made, functions perfectly, and saves an incredible amount of time and effort.

I own three other air hammers but this one is in another realm ! It is named Thor and I think it actually came from Asgard it is so powerful. Best buy ever from Amazon , hats off to Astro tools USA you knocked it out of the park with this beast! Thankyou.

This thing is an absolute monster. I totally didn't need it, but would buy it again, just caus it's cool af. It destroyed my sidewalk testing it out, this baddie is no joke!!
