4000 Nm Heavy-Duty 1-Inch Brushless Cordless Impact Wrench for M14–M42 Bolts

Description

The 4000 Nm Heavy-Duty Brushless Cordless Impact Wrench is designed for high-torque fastening and loosening work in industrial, construction, mining, agricultural and heavy-equipment maintenance environments. Its powerful brushless motor delivers a maximum torque of up to 4,000 Nm, making it suitable for large bolts, wheel nuts, machinery fasteners and other demanding applications. Brushless motor technology supports efficient power delivery and reduces maintenance requirements associated with conventional carbon-brush motors. The impact wrench offers multiple operating speeds, including approximately 1,250, 1,450, 1,850 and 2,100 rpm. The listed no-load speed reaches up to 2,500 rpm, allowing the operator to adapt the tool to different bolt sizes and fastening requirements. Its impact system provides listed impact-frequency settings of 4,000, 4,200 and 4,600 blows per minute, with an additional stated operating range of up to 3,500 impacts per minute, depending on the selected configuration. The tool uses a heavy-duty 25.4 mm, or 1-inch, square drive and is recommended for sockets measuring approximately 19–56 mm. It supports standard bolts from M14 to M42 and high-strength bolts from M14 to M30. The cordless design allows the impact wrench to be used in areas where access to mains electricity or pneumatic equipment is limited.
