40mm 1150W SDS-MAX Brushless Rotary Hammer


Highest Demolition Performance and Fastest Drilling Speed in its class


Product Info

Industry first AC Brushless Motor. Unique Maintenance-free Brushless motor provides significantly longer life. No carbon brush replacement required. None of the traditional problems from conventional brushed commutator motors​

  • Stable Performance under voltage drop situations. Unlike conventional electric Rotary hammers, drilling performance isn't affected as much by voltage drop from long extension leads on site.
  • Example: 100mm extension load, 2.0mm² conductor. Performance of conventional models drop by approximately 14%, new Brushless models decrease by just 3%.
  • Stable Performance when used with Generators. Brushless design operates consistently and without the traditional problems cause by generator use. Requires suitably sized Generator output.
  • Fastest Drill speed in its class - Up to 20% faster*
  • Highest Demolition Performance in its class - Up to 40% high performance*
  • Ultra low vibration due to original, spring-type dynamic vibration absorber & vibration absorbing side-handle - Approx. 15% lower vibration value*
  • Original, spring-type dynamic vibration absorber with a weight and two springs moves in the opposite direction to the vibration direction of the main body. This results in reduced vibration and improved operating efficiency.
  • Aluminium Housing Body (AHB) provides a super strong aluminium die-cast body with internal double-insulation making the housing more rigid, significantly enhancing durability of the motor unit.
  • Improved handling with constant speed control & 4-stage electronic switching to adjust the drilling speed and impact rate
  • One-touch quick change SDS MAX chuck
  • Large change lever & trigger switch - easy to operate wearing gloves
  • 2-mode – Hammer only and Hammer Drilling
  • Variable lock mechanism allows 12 different chisel angles (hammer only)
  • *A comparison of the model DH40MEY(G1) and the previous model DH40MRY. The results may vary depending on operating conditions.
