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

Used to remove chevy van upper ball joints, worked as expected..

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.

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👎

This CP product is perfect for home and light industrial. Although the tool is made in the pacific-rim, it has been produced to high quality control standards. The CP logo is a decal and is not cast into the body (as most of their products). It is comfortable in the hand and easy to control. The box is a great storage option as many other brands give you a flimsy plastic tray. The tool selection is limited, but a great starter pack. I love the quick release chuck as well! Overall, this product is a very good value from the top producer of pneumatic tools.
