What Customers Are Saying

Customers overwhelmingly praise this impact wrench for exceptional torque and reliability across demanding tasks like tire changes and suspension work. Reviewers highlight its powerful performance on stubborn lug nuts and brake components, compact ergonomic design that fits tight spaces, and two-speed variable control. Many emphasize outstanding value for the price, describing it as well-made and durable, with several purchasing additional units. Battery ecosystem compatibility adds convenience. A small number found torque insufficient for oversized applications, though most consider it a worthwhile investment that exceeds expectations.

Used about 6 times and in now just groans and won't spin. No longer have the receipt, and craftsman warranty is only for manufacturer flaws you can prove. So this is wear and tear? Buy a better brand

It's good for mostly everything but

I have loved every craftsman product I have gotten as well as I love how easy it is to exchange them if something breaks or stops working. I had bought this as I'm going into the automotive field and had no problems with it until one time I was taking off lugnuts and it completely locked up on me. It sounded like a gun going off but Lowes helped me with replacing it with no problems and I haven't had any problems with it since. I have used it 4 times the amount I did with the first one I got and...

Impact gun.

Would Recommend

Great price and great tool. Now I don’t have to use the lug wrench any more and get hurt. The impact tool does the job in half the time with no injury’s.

Didn't expect much from it for $99. But I was able to pull all four tires with six lug nuts each off. These were rusted on and this impact broke them loose with no issues. I was even able to put them back on all on just a single 2 amp hour battery. Very impressed with it!
