The Hikoki WH18DDW4Z is a cordless impact driver designed for demanding fastening tasks. It features a brushless motor that delivers a maximum torque of 140 Nm and a no-load speed ranging from 0 to 3200 rpm, allowing you to adjust the power based on the material you are working with. Measuring 134 mm in length and 185 mm in height, this tool is compact enough to fit into tight spaces without sacrificing strength. It weighs only 0.8 kg without the battery, which reduces fatigue during long workdays. The 1/4" (6.35 mm) tool holder ensures a secure fit for standard bits, making it a practical choice for professionals and DIY enthusiasts who already own compatible 18 V batteries and chargers.
