Chicago Pneumatic CP7165 vs CP7150 vs CP717

[kapster]

I've had the CP7150 for a year or so, DIY/farm use. I have nothing to compare to besides a harbor freight pos, but I would say it has alot of punch. Its downside is it's pretty hard to control without turning the air pressure down which I assumed judging from reviews but was ok with that for the price point.

I just noticed the new CP7165, pretty sweet air hammer. All aluminum housing(no plastic), built in air regulator, vibration cushioning, same 3/4 bore x 3.5 stroke of cp7150. I have not seen one review or anything on it so I assume its very new.

Some interesting specs:
Cp7165 11 joules of power 3.26 m/s^2 vibration 2500 bpm
Cp7150. 9.5 joules of power. 15.6 m/s^2 vibration 2300 bpm
Cp717. 7.3 joules of power 8.6 m/s^2 vibration 1800 bpm

So I'm surprised the cp717/ astro 4980 are as powerful as they say, or is it the CP7150/CP7165 are really that powerful? Are the slower, harder hits on the CP717 more useful for moving stuck stuff but on paper dont add up to as much power? Is it all in the .409 vs .495 shank and these numbers are irrelevant?

Another interesting thing is the vibration which I assume is what goes into your arm, the 7165 is a fraction of the vibration of the 7150 and less then half that of the CP717.

Air hammer power does not translate to specs at all.

If you want things to move get a 498 shank tool, the 401 shank tools don't transmit the same force as the 498 and will break over time. I have a CP 711 a CP 714 a CP 717 and an Astro 4980. the 498 tools are what I get out to make things happen. The 401 tools are for precision type work. A friend told me the s-o 3050 bla bla bla so I loaned him my Astro 4980 and after a week him and his co worker bought two and put the 3050 in the bottom of the tool box. He actually just paid me for the Astro I loaned him and kept as he needed it right away and It was all most new. Using the 498 tools don't rattle me at all during use they just make things happen. I don't see any difference using the CP or Astro but Chris from Astro is on here a lot and if you have any problems he will make sure they are fixed.

I've got a CP 7150 & 717, no direct comparison. The .498 hit a lot harder and to me has less vibration. Think 24oz ball peen vs 3lb mini sledge. I also have a Snap-on 3050 I had bought used and it has a tad more power then the 7150, but no by much IMO.

Pretty much the only time I use a .401 air hammer now is when I dont have a certain/specialty bit in .498 or dont want to destroy what ever the item is. Other then that .498 does 80% or so of what I need.

Bit selection is somewhat limited in .498, but the most common for me is a hammer bit, straight punch, taper punch & 3/4 chisel. I plan on a longer acquiring a longer straight punch & 3/4 chisel (12"), and wide chisel. A longer hammer bit would be nice if they made one. Get Ajax bits.

As others have said, .498 stuff is a completely different animal. I have a CP714, and an Astro "big nasty". I prefer the 714 whenever I can use it, which is most of the time. Smaller, lighter, and a very nice trigger. Big nasty has an on/off trigger, but when I need to drive leaf-spring shackle bolts, shear rivets, or whack the hell out of something, it can't be beat.

the .498 shank CP 717 is a beast but more care is needed. You can easily f-up a bolt with it. It's on my list of tools to get now that no one in my shop has one.

I've got the snap-on ph3050b, I think it's one the best .401 shanks and I get the job done with it

Sent me a free wrench for a die grinder, when I lost mine (probably still in the bottom drawer of a tool box; new one has red tape on it). Sure it probably only cost his company pennies, but he has a customer who will sing his companies praises for life !

Thanks for the info guys, so sounds like you can't really go by info. And doesn't sound like the 717/4980 are very controllable either? As in can you feather the trigger to get it started or is it on/off?

Plinker, that's awesome you have both. So which is more controllable, 7150, 717 or 3050?

As to featherability (new word) the 3050 edges out the 717, it seems pretty close to me though, individual results may vary. The 7150 can be feathered to a degree, but it takes practice. Not quite an on/off, but not as good a control as the 3050.

When going full blast with the 717 it does take two hands to control the thing. I got bit once, dont care to repeat that. Kinda smarted. That said, two hands should be used with a .401 unit at full blast as well.

The 717s I've used, you can feather. They're harder to control because they hit so hard. I always try to use 2 hands with an air hammer. A short barrel hammer will be more controllable but are more suited for chisling, not knocking something loose
