GRAPHITE 58G539 Rotary Hammer — One-Piece, Compact Design

GRAPHITE 58G539 — single-piece, compact design rotary hammer is a 900 W SDS+ tool designed for drilling, percussion drilling and light chiseling in masonry, concrete and similar materials. The tool delivers an impact energy of 3.4 J and combines rotary and hammer action with spindle reversing and stepless speed control. It supports drilling diameters up to 28 mm in concrete and brick, 13 mm in steel and 30 mm in wood. The ergonomic main handle with a non-slip grip and a 3 m rubber-coated power cable provide comfortable and reliable operation on construction and renovation sites. The kit includes additional drill bits, a drill chuck and adapter, depth stop bar, rotating auxiliary handle, lubricant reservoir and a carrying case.

Advantages

The single-piece compact design reduces bulk while maintaining durability for frequent on-site use. A 900 W motor with up to 950 rpm (rotary) and up to 5300 bpm (percussion) ensures consistent performance for drilling and light demolition tasks. The click quick-change system and included chuck adapter simplify bit changes. Stepless speed control, spindle reverse and an on/off switch lock for continuous operation increase control and versatility. The durable 3 m rubber-coated cable and CE certification confirm suitability for professional and DIY applications.

Suitable for

• Drilling holes in concrete and brick for anchors, dowels and fixtures
• Light chiseling and chip removal during renovation work
• Drilling metal and wood when fitted with appropriate bits
• Repeated on-site tasks where a compact, single-piece rotary hammer is preferred

How to use

Fit the appropriate SDS+ bit or use the supplied chuck adapter to install a conventional bit, securing it with the click quick-change system. Set the required speed and engage the percussion mode by applying light pressure to the tool against the work surface when hammer action is needed. Use spindle reverse for removing stuck bits or backing out screws. For continuous drilling, engage the switch lock. Keep a firm two-handed grip using the main and auxiliary handles while operating and observe standard safety measures, including eye and hearing protection. Allow the motor to stabilize at the chosen speed before full-pressure operation.

Recommendations

Use masonry bits for concrete and brick, HSS or cobalt bits for steel, and appropriate wood bits for timber. For drilling large diameters in masonry, start with a smaller pilot hole and increase drill size stepwise. Maintain the lubricant reservoir as recommended to prolong bit life, and avoid prolonged heavy loads to prevent overheating. Inspect cables and accessories before use and store the tool in the supplied carrying case when not in operation.
