Difference between cordless wrenches and electric impact wrenches
Release time: 2025-07-29
Brushless wrenches use brushless motors, while electric impact wrenches typically refer to tools using brushed motors. Brushless motors use digital circuits to control commutation, eliminating the need for carbon brushes and solving the problems of short lifespan and frequent maintenance associated with brushed motors.
The main differences between brushless and impact wrenches lie in their motor type, performance, and application scenarios:
Core Differences
Brushless wrenches use brushless motors, while impact wrenches typically use brushed motors. Brushless motors use digital circuits to control commutation and do not require carbon brushes, solving the problems of short lifespan and frequent maintenance associated with brushed motors.
Specific Differences
Lifespan and Maintenance
Brushless wrenches can last up to 20 years and do not require carbon brush replacement, resulting in low maintenance costs; brushed wrenches have a shorter lifespan (typically several years) and require regular carbon brush replacement.
Efficiency and Energy Consumption
Brushless wrenches have an efficiency of 80%-85%, saving 30% more energy than brushed tools; they are also quieter and run more stably.
Application Scenarios
Brushless wrenches are often used in high-intensity work scenarios (such as construction fastener installation), while brushed impact wrenches are mainly used for ordinary bolt tightening tasks.
