A new super-safe 8kg AVT rotary demolition hammer drill provides more than double the impact power of its predecessor whilst the patented Anti Vibration Technology cuts the vibration rating by more than 50%.

    This makes the new Makita HR4511C the best performing and safest hammer drill in its class.The Makita 4511C features the SDS Max drive chuck system and with a mighty 13 joules of impact energy and up to 2,750 blows per minute available, will drive a 45mm drill bit or 125mm diameter TCT core into concrete and masonry.Powered by a 1350watt motor in 110v or 240v format, the 4511C has a no load speed range of 130-280rpm and weighs just 8.4kg.

     In addition to this high productivity performance specification the Makita HR4511C is the safest tool available.The AVT protection system, which uses the pneumatic pressure generated in the piston chamber to move a vibration damper, cuts the machine-generated vibration by more than 50%.

    In rotary hammer mode this powerful machine is rated at just 7.5m/s2 and in hammer-only breaking mode with the "D" side handle in use the rating is just 7.0m/s2.

     The new 4511C features the 2-Mass rear handle system of sprung loaded fulcrums that effectively separates the main handle from the machine body, greatly reducing the transfer of HAV risks to the operator.

     Further protection is provided for this powerful hammer by the inclusion of the proven Makita torque limiter system that instantly disconnects the drive if the drill or core gets snagged.

      This machine is also double insulated to the highest electrical standards.

     The Makita HR4511C is a super-safe, high productivity hammer drill that will be essential for major site operations and particularly popular with the tool rental centres that require the rugged reliability of Makita products and the safest tool to offer their customers.Fore more information ,please visit   http://www.bossgoo.com/
