Buying Guide

Match drive size to the job

Choose 1/2" drives for lug nuts and heavy fasteners, 3/8" for lighter automotive and assembly work to balance access and torque

Prioritize torque rating

Higher torque (noted in N·m or ft·lb) is necessary for stubborn fasteners; compare the listed torque figures when selecting a value model

Decide between cordless and air

Cordless tools offer portability and come in voltage variants (e.g., 20–21V) while air impact wrenches deliver continuous high torque if you have a compressor

Check powertrain type

Brushless motors typically run cooler and last longer than brushed types, improving efficiency and longevity in cordless models

Consider bare tool vs. kit

Bare tools reduce upfront cost if you already own compatible batteries, while kits include batteries and chargers for first‑time buyers
