Review: Highest Value Air Hammer - 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.
Review: This is the one. - It's powerful. I have a few air hammers, including the bigger brother to this, the 498k, which is more powerful, but bigger, harder to use, and tool choices are more limited. The bushing sold to downsize it is a little clumsy ...the 401k is a better choice. A friend has a Snap-on, the power seems identical. And it's a great deal. "Good deal" and "snap on" don't belong in the same sentence.. This has been trouble free, as have many other Astro pneumatic tools.. The trigger is real good, but a little too much squeeze results in a lot of power..if I want to be delicate (funny term for air hammer work), I use an aircraft 2x rivet gun. Just a not so powerful, very controllable 401 shank air hammer. Any powerful air hammer might be limited by the hose and fittings. I just live with it. I blip the trigger...if you hold it down, the power drops a bit, the first few hits are harder than those that follow. Anything recommending some giant compressor for impact tools is weird, they just are usually not used continuously, so it isn't a factor like it is for running a sandblaster, needle scaling a bunch of rust, grinding, even painting. If you're doing suspension work, any small compressor that can fill it's tank to 120 or so psi will run this just fine. You just may have to pause while it refills.
