The Hilti Nuron SF 4-22 Cordless Drill Driver is a compact yet powerful tool designed for professionals who require efficiency and reliability in tight spaces and overhead applications. Weighing approximately 1.3 kg, its lightweight design enhances manoeuvrability without compromising performance.

‍Performance and Power

‍Equipped with a brushless motor, the SF 4-22 delivers a no-load speed of up to 2100 RPM and a maximum torque of 62 Nm in hard joint applications. This power enables efficient drilling and driving across various materials, including wood, metal, and drywall. The two-speed gearbox allows users to select between 610 RPM for high-torque tasks and 2100 RPM for high-speed applications, providing versatility on the job site.

‍Durability and Build Quality

‍Constructed with a full metal chuck and an optimised cooling system, the SF 4-22 is engineered to withstand rigorous job site conditions. The brushless motor not only enhances performance but also extends the tool's lifespan by reducing wear and tear. These features contribute to the drill's robustness, ensuring it remains a reliable asset over time.

‍Safety Features

‍Safety is a priority in the SF 4-22's design. The integrated Active Torque Control (ATC) system helps prevent the tool body from uncontrolled spinning if the drill bit sticks, reducing the risk of injury. Additionally, a bright LED work light located in the base illuminates the work area, enhancing visibility in low-light conditions and contributing to safer operation.

‍Battery Platform

‍Operating on Hilti's Nuron battery platform, the SF 4-22 benefits from longer-lasting batteries and energy-saving technologies. This platform ensures cordless convenience without compromising on power or runtime, allowing professionals to work more efficiently throughout the day.

‍User Experience

‍Users have praised the SF 4-22 for its balance between power and size, noting that it performs well in confined spaces and during overhead tasks. The ergonomic design reduces fatigue during extended use, and the intuitive controls make it user-friendly. However, some users have noted that the LED light's position at the base can cast shadows, which may affect visibility in certain scenarios.

‍Conclusion

‍The Hilti Nuron SF 4-22 Cordless Drill Driver offers a compelling combination of power, durability, and safety features in a compact form factor. Its performance and build quality make it a valuable tool for professionals seeking reliability in demanding environments. While the placement of the LED light could be improved, this is a minor drawback in an otherwise exceptional tool.
