Chicago Pneumatic CP7111 - Air Hammer,0.401 Inch (10.2 mm), Round Shank, Stroke 2.64 in / 67 mm, Bore Diameter 0.75 in / 19 mm, 3000 Blow Per Minute, Welding Equipment Tool, Construction

I was trying to remove a Nissan Titan (4x4) front hub bearing and it laughed at the 5 lbs sliding hammer that I rented at the local auto parts store so I tried my Craftsman air hammer on it as well and the bearing got a good laugh out of that as well. I ordered the CP7150 since from the stroke it was closest to the "Big Nasty" without the $200 increase in price. Now I'm not saying this is as good as "Big Nasty" but I put a 5' whip and Milton high flow quick connect on it as soon as it got here. I have all Milton high flows on my compressor piping as well.I also bought the Astro Pneumatic hub puller as well since this bearing showed no sign's of wanting to come off. This morning I did change my Craftsman air hammer to the Milton high flow as well since it was around before I ever knew about the high flows and what a difference they make. Anyway I went to work on the truck getting ready to find out how well the Astro Pneumatic hub puller was going to work but the CP7150 had other idea's. It broke the bearing loose in just a couple of seconds and had it spinning out, with a slight tilt it was also bringing the bearing out of the knuckle and the bearing hit the ground. Mind you my Craftsman is hitting A LOT harder now with the high flow but it still isn't hitting like the CP7150.For anyone wanting to know it's made in Taiwan but so are my Mac wrench sets, Blue Point tools and my next lathe will have been made there as well, Taiwan makes a lot of tools now and the quality is there so don't let that bother you. One of the best things you can do is make sure you have high flow connectors on ALL of your connections and you wont believe what a difference it makes.If you plan to place a quick change retainer on it I recommend getting the Grey Pneumatic CH1001. I have tried several of the quick change retainers and the only one I haven't had fail on me is the Grey Pneumatics, they are pricey but worth it.

I am a professional mechanic of 40 years. I have purchased many air hammers over the years and paid over $300 off the tool truck with fabled promises that they are The most powerful beast of an air hammer ever made. Been disappointed every time. So this time I figured "what have I got to loose?" I purchased this hammer and have been very satisfied! I am not going to tell you this thing is the strongest hammer ever made simply because I dont believe there is any test that could prove such a silly statement. All I can tell you is it works as good as any one I have ever used and it is a fraction of the price.

the product is great but that locking spring for the chisel is dangerous it needs to be replaced with quick connect.

Good hard hitting hammer. Always keep one as a spare

I have owned the original 715 zip gun that was already in well used condition when I acquired it 15 years ago. I used it while working on cars. Worked particularly well when installing "A" arm suspension bushings and cutting rivets on the radius arm bushing bracket on Ford trucks.I now work on semi-trailers. This past week I was replacing half of the bottom rail, side skins and uprights on a wrecked trailer, which are all attached with rivets (by the hundreds). My original 715 finally cracked its case. Although it still works, the barrel works loose too easy. I ordered this one and finished the job. This one appears to be as well built as my first one. I expect it to last another 15-20 years.If you are considering buying this gun, you need to realize that this is a long barrel model that doesn't hit as fast, but does hit harder. If you need a little more control, a short barrel model may be more to your liking. We use short barrel ones for setting buck type rivets.

This thing is insane. Have used it countless times to remove stuck, rusted in bolts, studs, etc. I have yet to find anything it will not knock free. Also good for popping rivet heads off with a chisel bit.The only downside is that the retainer spring has a very hard time retaining the bit because of how hard it hits. I chased bits around the shop for about 5 minutes before ordering one of the "quick connect" style fronts for this thing. Much better now. Still the best air hammer I have ever used, even compared to the "tool truck" brands.

So it seems the vale assembly is what goes wrong with these they are not sold anywhere on Amazon that I know of. Picked this up Sept. 2 it's now Sept 21 the gun is no longer working which using these at work quite a bit i get that they wear out but, but, when a husky last at least 2 months before going bad and beats out a main brand company that makes the same product... Not good. So if you buy any air hammer name brand price I recommend looking up the "air valve assembly" and buying at least 2 or 3 of them. If your gun is making the sssssh sssssh air sound the guns not bad it's that part that went bad. Gun was oiled daily not dropped should of at the least lasted 3 months. Wouldn't recommend this at all👎

I used this to remove the rear wheels from 2 MTD riding mowers. I tried to remove them with a puller, tried to pry them off, even used another brand air hammer and nothing would budge them. I used this one and it took them off with ease. You do have to hold it a little tighter than others because it packs a powerful punch. I'm going to try it on a 2014 Taurus that the hub is froze to the knuckle and the axle is froze in the hub and bearing. I've tried oem hub pullers that failed, claw pullers that failed, and 2 other air hammers that failed. Hopefully this air hammer will push the axle out and remove the hub from the knuckle.
