Product Description

Gisam 2800N.m Brushless Impact Wrench – Industrial-Grade Power for Makita 18V Battery Users

The Gisam 2800N.m Brushless Electric Impact Wrench is designed for heavy-duty automotive repair, truck maintenance, and industrial applications. With powerful brushless motor technology and compatibility with Makita 18V B-Series batteries, this 1/2-inch cordless wrench delivers the torque needed for the toughest fastening jobs.

⚠️ Real-World Performance Note
While the manufacturer advertises 2800N.m, independent user testing indicates real-world performance of approximately 900-950N.m . This is common practice among budget-friendly tools, and the actual performance remains exceptionally powerful – easily handling truck wheels, tractor bolts, and rusted suspension components .
