20V Brushless Rotary Hammer Kit (Model : 8910K)

20V Brushless Rotary Hammer Kit (Model : 8910K)

When it comes to quality, rotary hammer drills go beyond expectations. Super powerful motors, bit holders with a unique chisel rotation system, and ergonomically designed bodies make them the strongest hammer drills of all time! Cordless Brushless Rotary Hammer is also one of the most powerful ones in its class.
This robust machine delivers 2.2J of impact energy with a speed of 0 up to 1400 RPM and an impact rate of 0-4500 IPM, completely qualified for heavy-duty tasks at home or job sites.

The motor of this cordless tool enables maximum drilling capacity up to 28mm in wood, 13mm in steel, and 22mm in concrete. A torque limiter is also assigned for torque overload to prevent components such as armature from experiencing excessive torque loads.

The housing of the Cordless Brushless Rotary Hammer is made of die-cast aluminum, turning a conventional rotary hammer into a lighter and more impact-resistant power tool. This feature also adds superior heat dissipation, which lets you work for hours without feeling a thing.
For more information on the 8910K rotary hammer, scroll down to the detailed description.

Brushless Motor with High Impact Energy for Concrete Drilling: The brushless motor delivers 1.7 Joules of impact energy and an impact rate up to 5,600 BPM, enabling efficient drilling into concrete up to 24 mm in diameter, plus 28 mm in wood and 13 mm in steel – ideal for anchor installation and light demolition
Compact & Lightweight Design for Easy Handling: Weighing only 2.55 kg (with battery), this rotary hammer is significantly lighter than many competitors. The PA6+GF30 reinforced body keeps it durable yet easy to handle for overhead work or extended use without fatigue
Long Runtime with Dual Battery Compatibility: Runs up to 35 minutes on a fully charged 4.0 Ah battery. The tool accepts both 2.0 Ah and 4.0 Ah battery packs, giving you flexibility to swap in larger batteries for longer jobs or smaller ones for reduced weight when needed
