Porter-Cable PCC640B Impact Driver Review

We found the balance and ergonomic design perfect on the cordless impact driver from Porter-Cable. It has a battery level indicator which many brands cheap out on it seems, so it’s a nice change from Porter-Cable. The battery life isn’t the greatest actually, but it’ll do the job. Did well to drive some 4″ long screws we had laying around. Great power but this driver uses a brushed motor (see the difference between brushed impact vs non brushed impact) which is a major disadvantage to the long-term lifespan of the tool. The LED light is bright and powerful, it comes on when you squeeze the trigger on the impact. Works well to drive large lag bolts. Has enough torque to remove the lug nuts off my girl’s car. All in all, it does the job but the two major cons to this driver is the brushed motor and the short battery life. We give it 3 stars overall. Looking for the best impact driver?
