Key Features

Klein designed the 90-degree impact wrench in the USA to provide utility workers a better, more comfortable fastening experience in the field.

Klein tells us that it’s a first for the market; it features a unique bolt-through design that accommodates long bolt fastening applications. Its right angle gives you the ability to reach around a utility pole to work comfortably.

The Klein 90-Degree Impact Wrench isn’t short on muscle either. Powered by the DeWalt 20V Max battery line, the Klein impact wrench delivers 300 ft-lbs of max torque. It features a variable speed trigger, allowing for the tool to generate anywhere between 0-1,800 RPM, making it an ideal choice for fastening in wood, metal, and concrete.
