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.
• 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 30% high performance*
• Ultra low vibration due to Hitachi's original, spring-type dynamic vibration absorber & vibration absorbing side-handle - Approx. 26% lower vibration value*
• Hitachi's original, pendulum dynamic vibration absorber reduces the vibration by moving a weight and a leaf spring in the opposite direction to the movement of the hammer.
• 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
• Continuous operation function (Hammer only Mode) – keeps the tool running even after the trigger switch is released, making chiselling easier.
• 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.
