Battery-Powered Impact Wrench (Medium-High Torque Model)

Applicable Scenarios

Targeting heavy-duty automotive maintenance (e.g., disassembly/assembly of SUV chassis bolts and truck brake pad fixing bolts), medium-sized steel structure projects (e.g., workshop purlin installation), tower main body construction, and high-strength assembly of engineering steel pipe frames. It focuses on efficient handling of medium-to-large bolts, meeting the all-day operation needs of small-to-medium projects.

Core Features

High-performance brushless motor: the body temperature is ≤50℃ after 2 hours of continuous operation, avoiding power attenuation caused by overheating.

Intelligent disassembly button with torque memory function: can save the disassembly parameters of commonly used bolts, no need for repeated adjustment in the next operation.

850-1300NM torque coverage, combined with 2200/2600RPM high rotational speed: it only takes 3-5 seconds to loosen rusted bolts.

6000mAh large-capacity battery: supports 8 hours of intermittent operations. Equipped with fast charging function (fully charged in 1.5 hours), reducing downtime waiting.

Technical Parameters

Rotational Speed	2200/2600RPM (2-speed adjustable, suitable for bolts with different tightness)
Voltage	21V (continuous high-voltage output, ensuring stable release of high torque)
Lithium Battery Capacity	6000mAh (compatible with 21V batteries of the same brand, replaceable for extended battery life)
Torque Range	850NM-1300NM (compatible with M10-M22 nuts, easily handling rusted/tightened bolts)
Loosening Nut Range	M10-M22 (supports disassembly/assembly of nuts with washers, no additional tools required)
Bare Machine Weight	1.5KG (maintains portability despite torque upgrade)
