  • Capacities:
    • Concrete (with TCT Bit): 40 mm (1-9/16″)
    • Concrete (with Core Bit): 105 mm (4-1/8″)

• Advanced Anti-Vibration Technology (AVT):

  • Three-Component System: Effectively reduces vibration to a low 5 m/s².
  • Air Actuated Counterbalance: Directs air pressure to move counterweight pistons, actively reducing vibration.
  • Vibration Absorbing Housing: Features a spring-loaded main handle and upper housing that move independently of the motor and drive mechanism, isolating most vibrations from the user.
  • Integrated Damper Spring: Located at the base of the impact bolt to absorb impact vibrations from the drill bit.

• Enhanced User Control and Comfort:

  • Lock-on/Trigger Activation: In "Chipping Only" mode with push button start/stop control.
  • Constant Speed Control: Maintains speed under load for consistent performance.
  • Soft Start: Suppresses start-up reaction for better accuracy and control.
  • Variable Speed Control Dial: Allows users to match speed to the application for versatility.
  • Torque Limiting Clutch: Prevents gear damage by automatically disengaging gears if the bit binds.
  • Sequential Impact Timing: Provides timed hammering during rotation for up to 50% faster drilling.
  • Depth Gauge: Ensures consistent drilling depth for precision tasks.
  • Double Insulated: Adds an extra layer of safety for the user.

• Operational Efficiency:

  • LED Service Light: Alerts the user about 8 hours before brush replacement is needed.
  • LED Power Light: Indicates switch failure or cord damage.
