Key Features

1. Powerful 20V Battery System

Delivers reliable, cordless performance with enough power for impact drilling, screwdriving, and light chiseling. Ideal for on-site mobility and confined workspaces.

2. Dual-Speed Gearbox with High Impact Rates

Switch easily between two speed ranges and multiple impact levels to match the material—great for wood framing, concrete anchor installation, and even metal drilling.

3. Anti-Rotation Control

This advanced safety system senses abnormal tool rotation and instantly shuts off the drill to help avoid injury or tool damage—especially helpful in heavy-duty hammer drilling.

4. Adjustable Torque with Clutch Control

The 20+3 function selector lets users customize torque output for various fasteners and drilling scenarios. Higher numbers on the collar correspond to increased torque output for tougher tasks.

5. Enhanced Chuck with Metal Construction

The 1.5–13 mm metal chuck ensures solid bit retention and fast, secure bit changes. The self-lock system adds safety and usability for pros who change bits frequently.

6. LED Work Light with Auto-Timer

A built-in LED activates with the trigger and remains on for 10 seconds after release, illuminating dark corners and tight spaces to improve visibility.

7. Electric Brake & Belt Hook

The electric brake provides instant stopping power after trigger release for better control and faster task transitions. A built-in belt hook ensures convenient carry and storage between uses.

Best Practices for Hammer Drilling

  • Apply steady, linear pressure—avoid forcing the tool, which may reduce efficiency or overheat the motor.

  • Keep the drill perpendicular to the surface to reduce bit wear and improve hole precision.

  • If resistance increases during deep drilling, back out the bit slightly to remove debris and maintain smooth progress.

  • Let the drill do the work—smooth material flow is a sign of optimal speed and pressure.

  • Avoid side pressure, which can clog the bit flutes and cause stalling.
