This hammer generates a serious 2.1 Joules of impact energy at 4,500 BPM, providing the penetrating force needed for fast, clean holes in tough materials. The variable-speed trigger gives you precise control over drilling speed, from starting a pilot hole to powering through rebar. Four Modes, Limitless Applications Why carry multiple tools? A single dial unlocks complete jobsite versatility: Rotary Hammer Mode: Your go-to for drilling into concrete, brick, and block. Hammer-Only Mode: Ideal for light chiseling, tile removal, or stubborn fasteners. Drill Mode: For drilling into wood, metal, or plastic without the hammer action. Chisel Mode​ (with rotation locked): For controlled demolition, breaking tile, or chasing walls. Engineered for Efficiency & Endurance Brushless Motor Advantage: Experience longer runtime, more power per charge, and significantly reduced maintenance compared to brushed motors. SDS-Plus Professional Chuck: Change bits in seconds without tools. The secure grip maximizes power transfer and minimizes bit slippage. Intelligent Battery System: The included 4.0Ah batteries​ provide substantial runtime, and the 4-LED fuel gauge​ shows remaining charge at a glance. Share these batteries across the entire DongCheng 20V Max tool family. Designed for the Demanding User Comfort and control are built in.
