H45MEY AC Brushless, AHB Aluminum Housing Body, UVP User Vibration Protection, AC/DC 16 lb SDS Max Demolition Hammer Metabo HPT

User vibration protection banner

The H45MEY Demolition Hammer with AC Brushless Motor, UVP (User Vibration Protection) and AHB (Aluminum Housing Body) is the perfect combination of performance and comfort.  With highest demolition performance in its class, it can complete the most demanding jobs with ease. It features AHB construction that provides significant durability and extended tool life. UVP technology can reduce down-time and vibration related injury. The Brushless Motor allows the tool to operate over an extra long extension cord with reduced power loss, and also eliminates maintenance of armatures or carbon brushes. The push button impact selector also serves as a diagnostic tool to trouble shoot overload or overheating issues. This demo hammer delivers superior performance when powered by a generator due to an internal inverter circuit that regulates uneven power supply for ultimate jobsite performance.hi

  • Ultra efficient AC Brushless motor that permits the use of extra-long extension cords with reduced power loss, extends product life and eliminates maintenance of armatures or carbon brushes 
  • Superior performance when using a generator due to an internal inverter circuit that regulates uneven power supply
  • UVP (User Vibration Protection) technology greatly reduces vibration for comfortable extended use and fewer vibration related injuries via the use of internal counterweights and springs, as well as low vibration handles
  • AHB (Aluminum Housing Body) construction significantly enhances the internal and external durability of the tool. Externally the metal body construction is more resistant to jobsite impacts and harsh conditions than plastic counterparts. Internally, incorporating a plastic stator holder around the Brushless motor provides the internal double insulation construction that can protect the user from electric shock. The motor and hammer bearings are seated in the metal housing to reduce vibration and stress, and increases stability. During use, the metal keeps the internal gears secure and aligned preventing wear and power loss. Additionally- the metal body dissipates heat better, increasing overall motor life
