Ingersoll Rand 121/Q Super Duty Air Hammer, 3000 BPM, 2-9/32" Stroke

I bought these four weeks ago thinking that they were durable based on the reviews. The retaining springs broke on their first job and I don't know of any channels to replace them or the broken parts.

Good hammer. Not crazy powerful but gets job done. Much more comfortable to use than the cheap Kobalt hammer. Kobalt hammer hits harder but not nearly as controllable as this one.After a bit of use the barrel part loosened up. Had to tighten it a few times. Going to take barrel off to see if some locktite can be applied to threads. That’s the only problem I’ve had. Design flaw but easily addressed on job site.

Small compact an strong! Use this thing to remove upper ball joints on a 2011 Toyota tacoma. Took it out like butter. I also order a pneumatic (ch117) 1" daimeter hammer together it makes an awesome tool. For removing ball joint an u-joints

I wanted to chip some granite so I bought a 20 dollar Kobalt Air Hammer. Two shifts of four hours running it non stop pretty much trashed it. No umph left. OK, maybe I should have read the directions and added some lubricant. I did that before the second stint and the oomph was back but not for long. I might rebuild it when I get the spare time.Meanwhile paid 86 bucks for the Ingersoll Rand and am quite happy. The job I am doing is nonstop brutal hammering of rock. The Kobalt I am sure can handle the light work but this Ingersoll Rand feels like it is going to last. More heft and more power. 4 good turns at the rock and it's still quite peppy. I am oiling this one from the start so this review might not be completely fair to the Kobalt.Chisels from both fit the new hammer. Now if someone could point me to a chisel that fits this hammer which will not wear out I would be happy. I have to grind a new edge every hour or so and they are getting short.

I've used this a few times, several hours all together and it has performed and is comfortable to use. The retainer spring broke quickly so I recommend immediately buying several extra springs when you order. I purchased the Ingersoll Rand quick change retainer to try to bypass the short life of the stock retainer spring but after using the quick change retainer I think I'm going to go back to the stock spring and just keep several spares. The springs are less temperamental than the quick change retainer.

First let me say I went on the cheap for my first air hammer and learned my lesson. This unit does all the usual things needed for around the home. Remove tile, chip out grout, punch a hole through concrete or concrete blocks, etc etc. It's not over nor under powered for those uses and it's reasonable weight makes using it easy. It doesn't overly vibrate and isn't overly loud during use. It works perfectly with my  Makita MAC2400 Big Bore 2.5 HP Air Compressor  with no real wait time for compressor recharge time beyond the normal pauses for clearing debris or moving about.It seems about "just right" for typical home owner use.UPDATE: After a year of use this hammer is still going strong. used it on an outdoor flagstone patio re-grout. (One of those jobs that looked straightforward but turned into a nightmare) It's spent many many hours removing grout, breaking up decaying concrete base and never once even stuttered. It did break a retaining spring but that's to be expected. One of those few tools that is solidly made and worth the money.

This is an air hammer like none I've owned before. It is a real handful when you pull the trigger. I bought it for a specific purpose--driving out some very long bolts rusted into place in a large machine. A smaller air hammer I owned would sometimes, reluctantly do the job. This tool, if you can keep it pointed where you want, will knock out a 4" long 7/8-14 bolt solidly rusted into place. The pointed chisel will rapidly pound a huge dimple into a piece of solid mild steel. Paid only $100 for the tool and all accessories at Amazon, got in in three days and have used it a lot. Would recommend highly.

I had to re-tile some bathroom floors, but ran into a problem. The ceramic tile was apparently put down with an adhesive that was meant to last 100 years. In the first bathroom I used a chisel and hammer to remove the tile by hand which took me a week to get the tile up. There had to be a better way so I bought this air hammer and gave it a try.I was amazed how fast the tile came up with this tool. It works like a little mini hand-held jackhammer. I was able to remove the tile in just a few hours instead of a week doing it by hand. I am sure this handy little tool has many other uses that I may discover later, but for now I am very happy using it for tile removal.There is one thing you must be aware of. This tool uses an air compressor. I only had a 1 gallon compressor which is not even close to adequate. I had to buy an 8 gallon and it worked great.

Good Ingersoll quality tool. Compact yet powerful. Just wish it had a bit more power to each blow and a slower bpm. Then it'll be perfect!

Good quality, not the strongest one around, but lasts long.

Never use it. Didn't work at all.

Good value for the price.
