Rotary Hammer DeWALT D25733K-QS

The DeWALT D25733K-QS rotary hammer is a heavy-duty power tool designed for drilling and chiselling in concrete and masonry. Powered by a 1600 W motor and equipped with an SDS Max chuck, it delivers high impact energy and sustained performance for demanding construction tasks. The tool supports a maximum drilling diameter of 48 mm in concrete and produces an impact energy of 13.3 J, while a maximum no-load speed of 355 RPM balances control with efficient material removal. With a compact form factor — 115 mm width and 544 mm depth — and a tool weight of 9.5 kg, this DeWALT rotary hammer is built for continuous professional use.

Advantages

The powerful 1600 W motor provides consistent torque and performance under load, and the SDS Max chuck allows secure bit retention and fast bit changes for heavy-duty applications. A high impact energy of 13.3 J improves drilling speed and chiselling efficiency in concrete and masonry. The compact dimensions and balanced weight distribution make overhead and horizontal work more manageable while maintaining durability for on-site use. Operating at up to 355 RPM ensures controlled drilling progress and better bit life in demanding conditions.

Suitable for

• Drilling large diameter holes in reinforced concrete (up to 48 mm)
• Chiselling and demolition work in masonry and concrete
• Installing anchors, rebar dowels and through-holes for utilities
• Professional construction, renovation and structural work
• Tasks requiring long runtime and robust tool performance

How to use

Select an appropriate SDS Max drill or chisel bit for the intended task and secure it in the chuck according to the manufacturer’s instructions. Set the machine to the required mode (drilling with impact or chiselling) and start at low speed to establish the hole or starting point, then increase speed as appropriate for the material. Apply steady, even pressure — do not force the tool — and allow the hammer action to perform the cutting or chipping. For prolonged work breaks, switch off and disconnect the power before changing accessories or performing inspections. Follow all safety and operational instructions in the manufacturer's manual.

Usage recommendations

Use certified SDS Max bits rated for the specified drilling diameter and impact energy. Wear appropriate personal protective equipment (eye and ear protection, dust mask, gloves) and, when working in concrete, use dust extraction or wet methods where possible to reduce silica dust. For overhead or extended-duration tasks, consider auxiliary support or anti-vibration attachments to reduce operator fatigue and improve control.
