DHR400N 40mm (1-9/16")

18Vx2 Cordless Rotary Hammer


  • 8.0 Joules (EPTA) Impact Energy Delivers High Performance Equivalent to HR4013C
  • Newly-developed BL motor delivers high power and excellent performance equivalent to corded model HR4013C
  • Active Feedback sensing Technology (AFT) turns the motor off if bit rotation is suddenly forced to stop
  • Auto-start Wireless System (AWS) connects to compatible vacuum cleaners with Bluetooth
  • Low vibration achieved by Anti-Vibration Technology (AVT) & SOFT NO LOAD (suppression of motor speed during no-load)
  • BL motor generates less heat buildup and is ideal for prolonged use in high production applications
  • BL motor efficiently uses energy to match torque and RPM to the changing demands of the application
  • Dual LED job lights with preglow and afterglow functions
  • Torque limiter stops bit rotation if bit jams for increased operator safety and enhanced tool protection
  • 2-mode operation for "Hammering Only" or "Hammering with Rotation" for multiple applications
