DD/DM16BL-50I, a small but powerful cordless driver/hammer drill, is a power tool useful for applications requiring precise screw driving and drilling such as house renovation and construction. The next-generation PI (product identity) of Keyang Electric Machinery was applied. As a powerful but compact, lightweight cordless drill, it is ideal for both DIY users and professionals. Although high-power, large-capacity 2.0Ah battery was used, the battery of DD/DM16BL-50I is significantly smaller than our existing 14.4V cordless drill solutions, thanks to its the magazine-type structure newly adopted for easy mounting and convenient use of the battery. Its ergonomic design provides excellent grips and minimizes fatigue. The dual-speed gearbox maximizes versatility.
