Durofix Impact Wrenches

Durofix is a leading manufacturer of high-quality power tools, specializing in impact wrenches. Founded in the UK in 1965, Durofix has over 50 years of experience designing and building robust, reliable tools for professional use.

Impact wrenches, also known as impact guns or air wrenches, are power tools that deliver high torque output in short bursts to efficiently loosen or tighten fasteners like lug nuts or bolts. The compressed air or electric motor in an impact wrench rotates a mass to store kinetic energy, then releases that energy suddenly to create torque.

Durofix offers both cordless and air impact wrenches to suit different needs. Their cordless impact wrench line includes 12V to 18V models with lithium-ion batteries, providing portability and freedom from air hoses. For heavy-duty tasks, Durofix's air impact wrenches range from compact 1/2" drive models to 1" drive beasts that can generate over 1,000 ft-lbs of torque. All Durofix impact wrenches are engineered for durability, power and control across automotive, industrial, and construction applications.

Durofix Impact Wrench Features

Durofix impact wrenches are designed with professional use in mind, featuring robust construction and powerful motors to make short work of stubborn bolts. Here are some of the key features of Durofix impact wrenches:

Durofix Air Impact Wrenches

Durofix is well known for their range of pneumatic impact wrenches powered by compressed air. These air tools provide the high torque output and reliability needed for automotive and industrial applications.

Unlike battery-powered cordless models, Durofix air impact wrenches require an external compressed air source to operate. Most operate at 90 PSI with an air consumption between 4-9 CFM depending on the model. This allows mechanics to take advantage of shop air compressor systems when working in a garage or shop environment.

Durofix air impact wrenches use standard air hoses and connectors, making them compatible with most air supply setups. The hoses thread directly into the tool itself or use a quick-connect coupler for faster changes. Air hoses should be kept clean, kink-free and in good condition.

These pneumatic impact wrenches are known for being loud tools, producing noise levels around 85-95 decibels during operation. Hearing protection is highly recommended to protect mechanics' hearing with ongoing use. The noise comes from the rushing air and hammering action under load.

Popular Durofix air impact models include the 1/2" DWA681 that delivers up to 600 ft-lbs of nut-busting torque, and the 3/4" DWA682 for up to 1,100 ft-lbs of max torque. The DWA680 is a lighter 1/2" wrench well-suited for automotive use. All provide the trademark Durofix power and durability.

Durofix Impact Wrench Performance

Durofix impact wrenches are designed to deliver exceptional performance for automotive uses. They provide ample power and speed to make quick work of removing lug nuts and other bolts on cars, trucks, and other vehicles.

The high torque output of Durofix wrenches allows them to generate tremendous bolt removal force. Even stubborn, rusted bolts are no match for a Durofix impact gun. Most models provide at least 150 ft-lbs of maximum torque, while the heavy duty wrenches can produce over 1000 ft-lbs of nut busting torque.

In addition to brute strength, Durofix impact wrenches also offer great control and precision when needed. The variable speed triggers allow you to start off slow and then increase speed once the bolt starts moving. This prevents over-tightening or thread damage. The wrenches also have precise torque settings so you can dial in just the right amount of torque for a particular application.

Reliability and durability are hallmarks of Durofix power tools. The wrenches utilize heavy duty impact mechanisms and rugged housings that can withstand years of shop use. Many professional mechanics trust Durofix wrenches to hold up to daily use and abuse on the job. The internal components are engineered for long service life as well.
