Astro Pneumatic Tool 4980 0.498" Shank Super Duty Air Hammer/Riveter

unbelievable very strong and it's never make me done.

The one downside is the pneumatic bits that it uses they are expensive but it kicks the s*** out of snap-on's best The 3 things I wish that it came with a quick change bit The diameter of the bits are hard to get and expensive There is a better version of this out there but it is next to impossible to get people call it Big nasty Thor it is made by the same company and it is stronger but they're next to impossible to get Otherwise an absolutely great air hammer The snap-on fanboys will cry when they see this thing work Another downside of this air hammer is that it likes to launch things across the shop so when you're driving out pins make sure you have something to stop it on the other side

No regrets purchase my first air hummer tools, This Big nasty really worthy 🤙 great for big job Its Hit Really Hard and what more important way more cheaper than the leading Brand.

Hard hitter....great quality

I used a Mayhew Pro 32011 3/8 to 18-Inch Pneumatic Taper Punch to remove one of the two brake caliper carrier bolts, the ones with the trisquare heads, from a 2011 GTI rear axle housing with a Ingersoll Rand Model 123MAX Short Barrel Air Hammer. It was rusted in so badly, it had to be first drilled, which created a 13/16th hole bisecting the bolt to get around the axle hub (too hard for me to reinstall @ 120 ft/lbs + 180 degrees more). The last of the bolt came out but the I slammed the taper punch into its place before I realized it, my lack of experience rearing its ugly head. First, I put a 9mm 12 point box end on the taper to keep a second taper on the 3/8" diameter target of the woefully wedged original but that tore off the box end splines. So, I put a 3mm divot in the end of an 18" hammer bit so it would accomplish the same thing - stay in place while beating on the stuck 3/8 taper end but that puppy was in forever. So I went to Youtube University. Like a breath of fresh air, there was Torque Test Channel along with several opinions and perspectives from many videographers. I scrolled past those intent on comparing brands & sizes to SnapOn and Harbor Freight. I can't afford anything SnapOn more than a 7mm box/open and Harbor Freight is for those who know what's good and not so. I was interested in the Big Kahuna, a real mother, one dangerous to use. I had a vision of the one time I ran a jack hammer just long enough to learn when you weigh in at 160, you're just not going to make it. That's what I wanted now, but under a car. And there it was; two words, mean. The Torque Test Channel chart showed, the next larger I-R 135 was, for my purposes, no different in PSI impact. Welterweight. But the first entry, head and shoulders above, I mean, check your insurance policy, Top 'O the List was the Astro 4980 with 5,181 max PSI vs 3,946 for the I-R 123 or a 31% increase. The I-R 135 @ 4,989 is about the same price as the Astro Then the label: "Big Nasty," from a South Main Auto Repair video jumped right off my laptop screen. Seems the professionals in Upper New York run into similar situations on suspensions all the time. It took two days to get, unbelievable service from Amazon Prime (Imagine going thru all this using snail mail shipping as we all did 50 years ago), and a half hour to be successful. Why so long ? Hey, I have a Makita 5 gal compressor, a garage size, under the bench, unobtrusive, to change winter tires, change seasonal tire pressure and blow off lawn equipment. The "Big Nasty," is an air hog as one wag declared and followed with, ya gotta have at least 5cfms and this and that. My "Big Nasty," gulps air at the rate of 5 gallons/3-5 seconds, and then becomes ineffective. So it took longer that someone with a 30 or 60 or, "Oh ma gosh," an 80 gallon tank with a 2 stage compressor. But hey, those pauses allowed me to contemplate my learning. About a half an hour. When the stuck drift shot out about two feet and clanged on the floor, you can hear the sound, I smiled.

ive had this gun for over year and half, it has more power than snap on, over numerous times and different guns ,,when they could not do it they would call me,,i got it not knowing ,take a chance, but im happy with it, and I never had issues yet
