Overview
The JLBS-12V-DM03 is a compact impact tool built on a 12V platform with a 3/8 inch drive, sized for lighter fastening work. Torque output, battery capacity and included accessories are not listed, so match it to your job by drive size and voltage.
The 3/8 inch drive and 12V label point to a smaller impact tool meant for one-handed use rather than heavy automotive torque work. Because torque figures and runtime are not published, buyers with demanding jobs should confirm those numbers before relying on it for large fasteners.
