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.
