Milwaukee M18 FUEL 2853-20: the professional standard in cordless impact guns
The Milwaukee 2853's POWERSTATE brushless motor delivers 2,000 in-lb torque through a REDLINK PLUS system that monitors motor temperature and battery state to prevent damage before it occurs -- a genuine reliability advantage for professional daily use. The trigger feel is the most nuanced of any impact driver tested: the speed ramp is linear from the first millimeter of trigger pull to full speed, allowing slow-start precision that budget triggers cannot match. SHOCKWAVE chuck accepts any 1/4-inch hex bit one-handed without fumbling. Mode 4 auto-stop is the best implementation of screw depth control we compared, consistently seating screws flush without overdriving.

DeWalt DCF887B 20V MAX ATOMIC: best for 20V MAX platform users
The DeWalt ATOMIC is the choice for contractors and homeowners already on the 20V MAX platform. At 1,825 in-lbs, it covers all standard construction fastening and comes within 5% of the Milwaukee on deck screw speed. Three drive modes and a compact 5.5-inch length make it the most maneuverable impact driver in tight spaces. For 20V MAX platform owners, the DCF887 is the definitive impact driver choice.
Buying considerations
Brushless motor
Required for professional or frequent use. Brushless motors run cooler, last longer, and convert more battery energy to fastener-driving torque.
Drive modes with auto-stop
Auto-stop mode for final seating is the single most useful feature for preventing stripped screws and overdriven fasteners in finish work.
Compact length
Under 6 inches nose-to-tail fits into framing bays and tight spaces where longer impact drivers can't reach the fastener angle.
Battery platform
Choose the platform your other tools use. A second or third tool on the same battery system multiplies your battery investment efficiency.
Weight
Under 3 lbs for a compact impact driver prevents fatigue during 8-hour driving sessions. A heavier tool of equivalent performance is the wrong choice for all-day use.
Questions answered
Impact gun is informal terminology that can refer to either an impact driver (1/4-inch hex, for screws) or an impact wrench (square drive, for bolts and nuts). Impact wrench typically refers to automotive and heavy fastener applications; impact driver to construction and woodworking.
For general construction and decking, 1,500-2,000 in-lbs handles all standard fasteners. For automotive and heavy structural work, you want a 1/2-inch drive impact wrench rated in ft-lbs (multiply by 12 to convert).
Drive modes preset the torque output for different applications. Mode 1 is precision for delicate work, Mode 2 and 3 for standard fastening, Mode 4 is maximum power. Auto-stop mode cuts power when a screw seats, preventing overdriving.
A 5.0Ah battery on an 18V impact driver drives 400-600 deck screws or 200-300 structural screws. Battery life varies significantly with fastener size, material hardness, and drive mode used.
