Invento A78U Cordless Impact Wrench Launches with 150nm Torque for Pros and Diyers

The growing demand for high-efficiency, precision, and multifunctional tools in modern industrial production and fine craftsmanship has led to the development of the INVENTO A78U 1/2" cordless impact wrench. Engineered to meet rigorous professional requirements, this tool combines robust power, precise control, and ergonomic design to serve as a reliable solution for both professionals and DIY enthusiasts tackling complex tasks.

The INVENTO A78U's standout feature is its maximum torque output of 150Nm (on hard materials), placing it among the top performers in its class. The tool handles tough steel, dense wood, and threaded connections with equal capability. Its two-speed mechanical transmission allows users to switch between 550 RPM (low speed for precision work or fastening) and 2200 RPM (high speed for rapid drilling or disassembly), ensuring operational flexibility across different materials.

The impact mechanism delivers up to 35,000 blows per minute (BPM), enabling efficient drilling in concrete (up to 13mm diameter) and wood (up to 40mm diameter), significantly expanding its application range.

Beyond its power capabilities, the A78U incorporates thoughtful design elements. The included auxiliary handle helps distribute impact forces during high-torque operations, reducing operator fatigue while improving stability and precision. Weighing 2.6kg, the tool maintains durability without compromising maneuverability, even in confined spaces or elevated work areas.

The 1/2" (13mm) chuck size ensures compatibility with most standard drill bits and driver bits, eliminating the need for specialized accessories.

The A78U integrates with INVENTO's battery system, allowing users to share batteries across multiple tools in the brand's lineup. This interoperability creates an efficient tool ecosystem that reduces long-term ownership costs while improving workflow efficiency.

When operating the INVENTO A78U or any power tool, users should observe these safety precautions:

• Electrical hazards: Avoid liquid contact and inspect power cables regularly
• Mechanical risks: Wear protective gear and secure workpieces properly
• Thermal concerns: Monitor tool temperature during extended use
• Noise exposure: Use hearing protection during operation
• Ergonomic factors: Maintain proper posture and take regular breaks

The tool-only version requires separate purchase of compatible INVENTO batteries and charger. Users should consult the product manual and observe all safety protocols.

INVENTO provides a 12-month warranty for the A78U impact wrench, ensuring reliable after-sales support.
