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.

Decent, but unreliable


The torque output is decent, perfectly fine for regular garage work, the problem, however, happens under heavy use. I owned this when I worked as an auto mechanic, and kept it oiled, but I found that these have one significant weak link. The hammer carrier in the impact assembly is really weak. Under heavy use it will deform over time and start hitting the housing, then eventually it will crack and shatter. Other coworkers have owned the same impact wrench and have all had it fail in the same way. Don't buy if you are a professional mechanic.
