Performance

The Durofix RI12184-4T impact wrench delivers impressive performance with its brushless motor that provides high torque, speed, and runtime. This compact 12V impact wrench packs a punch with up to 300 ft-lbs of maximum torque and 0-2,900 RPM speed.

The brushless motor is efficient and powerful, able to deliver more torque and speed than comparable brushed motors. It enables the impact wrench to remove even the most stubborn bolts and lug nuts with ease. The high torque allows you to get the job done quickly without needing to upgrade to a more powerful tool.

In testing, the Durofix impact wrench removed lug nuts torqued to 150 ft-lbs with no issues. It provides more than enough power for most automotive repair and maintenance tasks. The variable speed trigger gives you control over the speed and power, allowing you to start off slow and increase as needed.

The Durofix also maintains its high torque throughout the battery life. There's no drop-off in power as the battery drains, so you can count on its consistent performance. The brushless motor helps maximize runtime as well compared to brushed motors.

Overall, the Durofix RI12184-4T delivers best-in-class power and runtime in a compact 12V impact wrench. The high torque brushless motor provides all the performance most DIYers need for their automotive projects.

Battery

The Durofix RI12184-4T G12 impact wrench is compatible with any G12 12V (10.8V) lithium-ion battery from The G12 Pro Series range. This gives you flexibility to choose the battery capacity that suits your needs.

The 2.0Ah battery can deliver up to 265Nm of max torque and charges in just 30 minutes. For extended runtime, the 4.0Ah battery provides up to 530Nm of max torque and charges in 60 minutes. The compact 2.0Ah battery keeps the overall weight down for reduced fatigue during overhead tasks.

Battery life depends on the torque setting used. At lower torque settings, the battery will last longer before needing a recharge. With heavy fastening applications, expect 15-20 minutes of continuous runtime from a fully charged 2.0Ah battery. The 4.0Ah doubles this to 30-40 minutes. This is sufficient for most tasks, however it's recommended to have a spare battery on hand for all day use.

The brushless motor maximizes efficiency to get the most out of each battery charge. There are built-in overloading and overheating protections to prevent battery damage. Overall the lithium-ion battery delivers reliable power with fast charging.

Features

The Durofix RI12184-4T G12 impact wrench comes equipped with several handy features for automotive repair and maintenance.

LED Light

One of the most useful features is the built-in LED light. Located right above the collet, this bright LED light illuminates the work area when you're working in dimly lit spaces like under the hood or beneath a vehicle. The light eliminates the need for a separate work light.

Variable Speed Trigger

The impact wrench has a variable speed trigger that gives you precise control over the speed and torque. Unlike some wrenches with only single speed, this trigger allows you to start off slowly and gradually increase speed as needed. This helps prevent over-tightening and stripping of bolts.

Brushless Motor

At the heart of this impact wrench is a powerful brushless motor. Brushless motors have excellent durability, run cooler, and provide more torque than brushed motors. This means you'll experience less wear-and-tear and more power in a compact wrench. The brushless motor gives long lasting, maintenance-free performance.

Comfort

The Durofix RI12184-4T impact wrench is designed for comfort during prolonged use. The tool features an ergonomic grip that fits nicely in your hand. The grip has a rubber overmold that provides cushioning and prevents slippage. This allows you to keep a firm hold on the tool, even when your hands get sweaty.

Vibration is well controlled thanks to the brushless motor and proper internal balancing. There's minimal hand vibration, so you don't have to worry about numbness or tingling during extended use. The impact wrench won't cause fatigue in your hands and arms like some cheaper models.

Overall, the ergonomic grip and low vibration make the Durofix RI12184-4T comfortable for all-day use. Whether you're a professional or DIYer, you'll appreciate how easy it is on your hands. The comfort-focused design enables you to power through tough jobs without pain or strain.
