3.5J Brushless Cordless Rotary Hammer (Model : 8679)

The construction site will definitely need it. The freedom and power of the 8679! This brushless cordless rotary hammer is here to become your partner in the heavy-duty crime!
Equipped with a 20V / 4.0 Ah lithium-ion battery pack, it’s not only about hammer drilling and chiseling. It’s about the efficiency and performance the 8679 delivers, even in tough and heavy-duty jobs.
  • High Impact Energy for Heavy‑Duty Concrete Drilling: Delivers 3.5 Joules of impact energy and an impact rate up to 5,400 BPM, allowing you to drill holes up to 24 mm in diameter into concrete. This makes the 8679 suitable for demanding tasks such as installing large anchors or breaking through reinforced walls
  • Brushless Motor with Dual 4.0 Ah Batteries: The brushless motor provides higher efficiency, longer runtime, and less maintenance compared to brushed alternatives. The kit includes two 4.0 Ah lithium‑ion battery packs, so you can keep working while one battery charges – ideal for all‑day jobs without extended downtime
  • Robust Hybrid Construction for Job Site Durability: Body combines PA6+GF30 (glass‑fiber reinforced nylon) with die‑cast aluminum components. This hybrid design offers excellent impact resistance, structural rigidity, and heat dissipation, ensuring the tool withstands tough conditions while keeping weight manageable (4.26 kg with battery). Includes SDS‑Plus chuck, auxiliary handle, and dust cover for cleaner operation.
