I bought this tool with the tire maintenance kit for $49.99. The price is much cheaper than my Craftsman HD impact wrench and my CP impact wrench. Just don't know whether this wrench is powerful enough to handle wheel nuts or not. I had to overhaul this wrench with the trigger valve and spring, and added oil into the hammer chamber. There was no oil inside the hammer chamber when I took out the oiling screw. I also had to tighten the screw at the forward/reverse valve at the neutral position. Once I fixed these problems, the impact wrench works fine. What is the hack, I wait for Christmas when the price drop back down to $24.95 to get one more. If I can overhaul and fix the problem, it is a good tool for occasional use.
In short, this gun "could" be a good gun however it starves for air. The trigger mechanism doesn't open the valve up enough - I played with it for days - I'm an Mech Engineer with a PhD and real hands-on experience - I know how to design and build tools - the valving mechanism on this just starves it for air. As a test, take out the air inlet valve mechanism by 1- remove the inlet port (don't drop the exhaust silencing balls) 2 - pull out the spring and valve Now put the inlet port back in - hook up to your compressor. I found it has considerably more torque now. That's the easy part. I also found that the air into the air motor is restricted by poorly drilled holes. There are slots in the throttle control that don't get air because of misalignment of the air inlet hole and the throttle control body (control switch on back).
Did not realize that I needed a larger tank to operate this successfully. Also requires oil to get it up and running so make sure you get that also. It automatically tries to add a 50ft 3/8" hose to your cart when you order this. It says right in the manual for this item that a 3/8" hose should not exceed 25ft. Using a longer than 25ft hose will impede the performance. Seemed like a good piece of equipment though.
After a year long storage, my old 1/2" impact wrench that I had owned for 40 years and which had served me well. Despite disassembling it and cleaning/oiling it it refused to work well, so I bought one of these Craftsman units.
It seem very well made and finished so I had high hopes.
Alas, when I hooked it up to air (9 CFM capable at 90 psi) it was immediately obvious that something wasn't right.
No-load, it revs VERY slowly as if getting FAR too little air, and it lacked enough torque to even remove lug bolts from a properly torqued VW Jetta wheel that my 110v plug-in and 18v Ryobi impact wrenches easily, instantly and effortlessly zipped out.
I found even at 120 psi, I could hold the 19mm deep socket IN MY HAND, and prevent the Craftsman from rotating it! I don't know how much torque the unit was producing, but I can tell you it was FAR less than 90 ftl bs (the torque of the VW lug bolt).
I would like to think I just got a bad unit, but sadly, other reviewers noted similar shortcomings in their reviews.
I had bought this impact because my craftsman electric 1/2" died on 2/06/17.
first job with it was to take off my 85ft.lb. lug nuts they wouldnt budge , checked them with my snap-on torque wrench and sure enough all of them were 81-85 ft. lbs..
I thought must be a fluke ..I have a 7.5 cfm 80 gallon compressor and use impacts daily as an ase master tech in my own business..
naturally I was curious ..I opened the impact up to find the rotary cylinder has a huge casting flaw in the top center , a half moon divot from the front to the back , no wonder the **** thing stalls with hand pressure...I go to return knowing as I grew up sears always honored defective and broken tools ,lets be honest craftsman is sears strongest foot in the consumer world..
long story short both the cashier and manager were extremely rude to a level that even Im not used to ...and the new policy is NO RETURNS WITHOUT A RECEIPT under any circumstances on pneumatic tools, which I conveniently tossed while thinkin "its craftsman I wouldnt have to worry" ...last time I ever purchase a craftsman tool Ive spent literally thousands over the years and watched as the tools lost quality..
This time Ive had enough ,2 impact guns in one month, from the same brand I held in my hand when at 6 years old my grandfather handed me learning to fix things..sad.
Got a new one and trade it in for not working.
Got another one still not working..
JUNK NOW POWER.
Bought the combo package 26 gal air compressor w/ air ratchets, within less than a year with minimal use I just had it the air rachet replace. Sales rep at Sears said there notarise for going out and recommend to upgrade to the pro series. Air compressor and the other rachet works great so far.
this impact has the torque I need to loosen or tighten bolts & nuts in my garage I would recommend this product to all my friends
I would defiantly recommend this product it's very good and worth the money
