Our Take

Best for: Mechanics and DIYers needing a compact impact wrench.

The DEWALT DCF921B ATOMIC 20V MAX 1/2 in. Impact Wrench is a compact yet powerful tool for fastening tasks. It generates up to 300 ft-lbs of fastening torque and 450 ft-lbs of breakaway torque, enough for most automotive and construction jobs. The four speed settings and precision wrench control let you avoid overtightening, while the timber screw mode optimizes speed for wood applications. The onboard LED with brightness control illuminates dark work areas, and the hog ring anvil allows rapid socket changes. The glass-filled nylon housing resists damage from oils and solvents, adding durability. 99 (44% off), this is a strong value, especially if you already own DEWALT 20V batteries. The main drawback is that it's tool only, so you'll need to supply your own battery and charger.

Price Analysis

At $134.99, this impact wrench is 44% off the original $239.00 list price. It's an excellent discount for a tool-only model from DEWALT's ATOMIC line. This is a great time to buy if you're already invested in the DEWALT 20V system.
