Matco W7150K1, 1/2" Cordless Impact Driver
Matco is a professional tool company, servicing mechanics, like Snap-On does. However, their tools don't usually have as high a price as Snap-On's do. I won't get into a discussion about which is better, although I did choose their 1/2" cordless impact over Snap-On's offering. That's mostly for the high amount of power it offers. This impact gives you 780 ft. lbs. of reverse torque, with burst of 1,100 ft. lbs. of torque for busting nuts loose. That's ties for the most power than I've found in any cordless impact. The power train is all metal to handle that much torque. At 6.8 pounds, that's an incredible power to weight ratio. It comes with two 3.0 Ah Li-Ion batteries, a charger, and a storage case.
