Craftsman 1/2 inch composite impact Wrench - Great Buy!

I've had this for about 5 years now. At the time, I was looking for a good, reasonably affordable impact wrench and saw this at Sears. I bought it to take off some 36 mm axle spindle nuts of a Honda Accord. They came right off! The compressor I used was a Sears 25 gallon Craftsman Professional with a 3/8" - 50 ft. black rubber hose. I was going through the manuals and instructions for my tools and found the one for this impact wrench and it stated if the hose was going to be longer than 8 feet, then to go with a 1/2" hose. This would be something to keep in mind when purchasing this to compensate for pressure loss from long hoses. I had been using this wrench just fine for years. Great impact and affordable. It is also lightweight in comparison to a lot of other 1/2" impact wrenches. If you want to go with more torque, then I would get the IR 2135TIMax. It has 200 ft. lbs more torque than this one. Otherwise, you can't go wrong with this Craftsman 1/2" composite impact wrench.

Great Impact Wrench For The DIY


This is my first air impact wrench. I’ve had mine for over 2 ½ yrs now and its worked very well. I’m a DIY maintaining our two vehicles and have never had a problem removing lug nuts or bolts. (I use an 8 Gal. air compressor with 25 ft. rubber hose) Back in March 2014, the Sears I went to was closing, so I got around 40% off retail price, so I only paid around $50 for it. (What a deal) Its light weight, very comfortable to use. The trigger is very responsive and I love the look of it. Of course the shinny part on mine is all scratched up now. This air wrench is very durable too. I just put oil in the air inlet tub before each use and start working. Another great Craftsman product.

Shows Promise, But Doesn't Deliver.


The plus side to this impact is that it is light and quiet. It also has a swivel air fitting. It has a reasonable amount of torque. The negative is that it worked for a couple days and then died. I am a professional mechanic and I hoped that this impact would work in a limited capacity for light assembly work. It doesn't seem to be reliable for every day duties. I am going to return it ASAP for a replacement.

Plenty of Power


This is a replacement impact wrench as the trigger on the old one failed (common problem) after many years of ownership/use. I have another, less powerful Craftsman impact wrench that puts out 340 lb-ft of max torque, It is much older and has been very reliable (only oil it before use), but it cannot remove lug nuts put on by the Ford dealer's mechanics as they almost always over-tighten them. This one has plenty of power for removing these lug nuts and suspension parts on my Focus and my son's classic Cutlass. I use the second forward setting for installing the lug nuts and tighten with a torque wrench, and this works perfectly.

I have an older Craftsman oilless compressor that puts out 6.4 CFM at 90 psig, and I have a Craftsman 3/8 in. rubber air hose with 3/8 in. quick connect fittings so there is plenty of air to run both of these wrenches. I purchased online and picked up in store at half the regular price. I only gave it 4 stars because of the trigger issue on the old one which hopefully has been addressed on this newer version.
