Product Introduction
This 21V lithium-ion ratchet wrench also adopts a brushed motor design. On the basis of maintaining stable power, it optimizes torque output. The bare machine is slightly longer, providing a more solid grip. It is suitable for moderate to light maintenance operations, balancing power and operational stability. No wiring is needed, and lithium-ion power supply is more flexible. It is suitable for frequent use by professional maintenance personnel and families, with high cost performance.
Specifications
Voltage 21V, brushed motor, drive head size 3/8 inch, maximum torque 45N.m, no-load speed 250RPM, forward current 3.84A, reverse current 3.62A, bare machine length 38cm.
Product Features
Compared with models with the same voltage, the torque is increased to 45N.m, providing stronger power to handle slightly more complex disassembly operations. The brushed motor delivers stable power output, with consistent forward and reverse current and balanced energy consumption. The 3/8-inch drive head has strong versatility and is compatible with most sockets on the market. The 38cm bare machine length provides sufficient grip space, making long-term operation more labor-saving, with constant no-load speed and stable work efficiency.
Applications
Suitable for scenarios such as regular automotive maintenance, light maintenance of mechanical equipment, assembly of small building components, and hardware maintenance. It can not only meet daily household use but also cope with regular operations of small repair shops, adapting to various complex working conditions.
