Chicago Pneumatic CP717K - Kit for CP717 Air Hammer, Welding Equipment Tool, Construction, Heavy Duty Case, CP717 Air Hammer, 4-piece 0.498 Chisel Set, Spring Style Retainer

Holy busted ball joints batman, this thing is an absolute beast. If you're tired of your old pansy Snap On or IR air hammer, then you found the right place in Amazon tool topia. Sure you could save the money, and continue to be frustrated while seized parts laugh at your over priced, under powered air tapper. Or you could step up to the plate with the CP717 and blow those rusted nuggets to the Jiffy Lube down the street.I've used an IR air hammer for many years. Also tried the supposed best Snap On hammer for a few weeks to see how well it performed. While both are good air hammers, nothing Ive owned, used, or borrowed has come close to Bigger Nastier here. It will pretty much beat anything into submission. It saves so much time with every day tasks. Makes suspension work so much easier. Plus if you're working on an old rusty turd, you pretty much can't afford to not buy this tool. If you already own an air hammer, you will want to keep that one when you buy this one. Because this one is too over powered for certain tasks. It can and will, literally destroy things. The CP717 is like Thor and his hammer. Sometimes you don't need Thor though, you may just need Rocky (like before all the training, at the beginning of the movie). So keep your old gun in your arsenal.The hammer does have a really nice trigger control, so you don't have to give everything "full beans" if you don't want to. But it can get out of hand fast if you dont have a steady hand. You will need ear protection, and eye protection. The air hammer itself isn't that loud, but it hits so hard, the noise can be unbearable after more than a few seconds. Wear safety glasses too because the shrapnel created by Thor here will do some serious damage. Made that mistake the first time I used it. I got lucky, but sure scared the poop out of me. So be smart and wear safety gear. While we may have the power of Thor, we certainly take more damage than him.If you're trying to decide between this hammer and the Astro 4980, I'd go with the CP. The Astro is just a copy of the CP. I'm not saying it's not a good tool. Eric O swears by it. But Astro tools are typically lower quality. Not bad quality, just less than CP. That is obviously my opinion. But when I buy a tool like this online, I have to think about the process of getting it warrantied, or repaired. Seeing as how I can't just walk into a store, or wait for my tool truck guy to come to me and fix my CP or Astro...I'd rather have something with a better reputation of lasting.One last thing I will add. Don't buy the cheap air hammer chisels and bits on Amazon. They are very brittle and will shatter and blind one of your coworkers, or take a piece of your flesh and send it to the moon. Buy the .498 CP bits only. They are made specifically for the unholy power of the 717. I have used this hammer quite a bit, and the CP bits hold up pretty well. By that I mean they don't shatter. They do wear down like any other chisel, and will need to be put on the grinder occasionally. But at least they are "safe".I love this air hammer. I wish I had bought it years ago. You will love it too. I didn't bother getting the quick release chuck for it. I don't think it's necessary. Once you're used to the spring retainer, it's no big deal. If you do get the quick chuck for it, make sure to put lock tite on the retaining screws.

This thing is absolutely amazing. One thing I won't hold against it, but people need to know is the broader "hammer" looking bit has been redisgned and ships loose. It does NOT fit in the case in the original spot. However, it does fit in there loosely. I figured it was worth noting, though I didn't take a star away because it's a small thing. It's simply slightly bigger than what is in the picture. A slight disappointment I had is since it's blow molded, and made to fit the tool like a glove, it wouldn't work with a quick release installed. However, I solved that by heating the blow molded case with a heat gun in the area where it didn't fit, then closed the case firmly. This melted the new profile of the quick connect in the case. Problem solved. Now evertything fits perfect. This tool will either break something loose or BREAK whatever it is you're trying to move. It really is incredible. it's a TON of cash, relative to others. It's biggest selling feature, which is often not mentioned, is the trigger. It's so easily manipulated you could probably nail a picture frame hook on a wall with it. You can modulate it that smoothly. It's not like a trigger switch like the vast majority of air hammers. Then when you give it full trigger it will almost move mountains. The first thing I "tried" it on was a 1/4" piece of flat steel. I literally dented it. I made 1/4" flat steel concave in a matter of seconds. The first real job I used it for was divorcing steel wheel spacers from aluminum wheels, that had been torqued to 500 ft/lbs for 4 years. The 4lb sledge did nothing. The airhammer removed them with 1/4 trigger.

If I could give this a 10 star, it would happen. I’ve got about 30k in tools and this CP is hands down one of my best problem solvers against the northern Minnesota rusty vehicles. If you live where they salt the roads, get this beast and save hours of time and hassle. The hammer is such a tank the bits take a beating but are still excellent quality, still 100% worth it!

Cuts frame bolts and rivets way easy.. and the trigger control is awesome... you can make just single hits to Wide open.. I cant really put it into words how much this thing dwarfs all my other air hammers... its a monster and just eats what ever metal you place in its way yes its controllable to the point you can gently tap in a bearing race or flatten a rivet... I'm way happy with it... those bushings don't stand a chance now ! lol

So much more powerful than the snap on or matco tool that costs more. I've even used it for cutting broken engine mounts on a kenworth and it saved me hours of work. It is a little too much for smaller jobs though and be careful not to mix up the bits, these take 1/2" bits, other air hammers use 3/8" bits and I'm sure that they would ruin this hammer if you ever mixed them up.

This is the best 0.498 air hammer kit you can buy. The bits it comes with are made by Ajax and the case is well built. The CP 717 hammer is the original “Big Nasty” Made in Japan. The Astro Pneumatic version 3970 is a copy of this hammer and is also very well made in Taiwan. That being said, considering how expensive individual Ajax bits can be, the overall value of this set when caught on sale cannot be beat. Ajax bits come with a lifetime warranty which covers breakage but not wear. So you’re covered and will get your money’s worth. Using inferior bits will result in a lot of breakage. These bits in the kit will stand up to the carnage this air hammer is capable of.

Spent 2 weeks researching CP717 and IR132. I own a Snap On 3050A air hammer. Wanted something with more power. I have been a dealership technician for 30 years working on 3500,4500,5500 Rams. I bought the CP717 this air hammer has a ton more power than the Snap On. It is also a .498 shank I spent 2 weeks talking to CP and IR technical reps about BPM verse bore and stroke. By far the CP is the hardest hitting. You will not be dissatisfied.
