  • AHB (Aluminum Housing Body) construction significantly enhances the internal and external durability of the tool
  • Large change lever located for easy access on top of the tool, rotates for hammer drilling, hammer only or neutral
  • Push button impact rate selector lets you easilychange the angle of the bit to preform precise work
  • Built-in protection circuit prevents damage to the tool in the event of an abnormality like overload, binding, overheating etc.
  • 9.9 ft-lbs of impact energy for busting through hard material

The DH45MEY 1-3/4" SDS Max Brushless rotary hammer is the newest rotary hammer in the Hitachi lineup. With the highest drilling and demolition speed in it's class, this hammer is made for hard work. It is constructed with the new AHB (Aluminum Housing Body) construction that provides significant durability and extended tool life. UVP (User Vibration Protection) Technology provides vibration protection by first utilizing a polymer coated vibration absorbing handle, then lessening vibration even more with the use of an internal counter balance. The brushless motor provides a no-maintenance tool so you don't have to stop working to perform routine carbon brush changes. Brushless technology also allows you to run the tool on a portable generator and not worry about work being slowed by voltage drop under loads. The DH45MEY should be the next tool in your jobsite arsenal.

The RP350YDH 9.2 Gallon Commercial HEPA Vacuum is used for the collection of dust generated when concrete and wood are ground, cut or drilled, for general cleaning, and for the collection of water spilled on the floor. It comes with two HEPA filters to capture more harmful dust particles, and helps with compliance for the recently instated OSHA 1926.1153 Crystalline Silica Dust Regulation. The RP350YDH can be used with Hitachi Dust Collection Attachments as well as other universal attachments in the market.

Make drilling dust in the workplace a thing of the past with Hitachi's line of dust collection attachments. The 115451 utilizes powerful suction to adhere to surfaces around the drilling point, ensuring no dust escapes. Pair with a HEPA filter for unparalleled protection from particulates.
