Rotary Hammer HITACHI DH45ME 1500 W, SDS Max, 310 RPM, 45 mm Concrete Drilling

HITACHI (Hikoki) DH45ME is a corded rotary hammer designed for heavy-duty chiselling and drilling in construction and renovation projects. With a 1500 W AC motor and an SDS Max chuck, this tool provides a combination of sustained power and compatibility with standard heavy-duty bits. The hammer delivers up to 310 RPM (rated range 120–310 RPM) and an impact energy suited for demanding concrete work, while its compact 535 mm depth and 9 kg weight balance on-site mobility with jobsite stability.

Advantages

The DH45ME integrates a high-input motor with efficient mechanical impact transmission to achieve consistent drilling and chiselling performance in reinforced concrete and masonry. The SDS Max chuck ensures secure bit retention and easy bit changes. The tool’s rated speed range and substantial impact energy provide control across drilling diameters up to 45 mm, and the corded AC power supply offers continuous operation without battery swaps. A compact body depth and a balanced 9 kg weight make the rotary hammer practical for overhead or confined-space applications.

Suitable for

• Drilling holes in concrete and masonry up to 45 mm diameter
• Chiselling and light demolition tasks on reinforced concrete
• Construction, renovation and installation work requiring continuous AC power
• Use with SDS Max chisels and large-diameter drill bits

How to use

Before use, confirm the power supply matches the tool’s AC requirements and inspect the bit and chuck for wear. Fit an SDS Max bit or chisel until it locks in place. Select the appropriate speed within the 120–310 RPM range and engage the hammer or rotation mode as required by the task. Apply steady axial pressure without forcing the tool; allow the hammering action and motor power to do the work. Keep a firm two-handed grip and maintain correct body stance to control kickback. After finishing, switch off and unplug the tool before removing or changing bits and perform routine cleaning and inspection.

Usage recommendations

For efficient drilling in reinforced concrete use appropriately sized SDS Max bits and start with a pilot hole when possible. Wear appropriate personal protective equipment including eye protection, hearing protection and dust control devices. For prolonged tasks, monitor tool temperature and allow periodic breaks to prevent overheating. Follow manufacturer maintenance intervals for optimal performance and service life.
