Rh15006 drill rotary hammer

Start by matching the task to power, chuck system, and drilling capacity. For frequent masonry work, look for models around 1.5 kW with up to 5.5 joules of impact energy to speed through concrete. Check the chuck type: an SDS-plus chuck enables quick bit changes and secure retention during hammering, while a straight 20 mm chuck uses standard bits. Consider concrete drilling capacity (up to about 32 mm on stronger options) and ergonomic features to reduce fatigue during long sessions.

The complexity comes from how the chuck type, impact energy, and no-load speed work together to deliver performance. An SDS-plus chuck allows rapid bit changes and greater retention under hammering, which matters for heavy masonry work, versus a plain 20 mm chuck that uses traditional bits. Power (around 1.0–1.5 kW), combined with about 850–950 rpm no-load speed and around 5.5 J of impact energy, determines drilling speed and through-put, especially in concrete up to tens of millimeters.

A DIY homeowner typically benefits from a balanced model that handles occasional masonry tasks with comfortable weight and reliable build, suitable for mounting shelves or heavy fixtures. A professional contractor, however, often needs higher power (about 1.5 kW), a robust chuck system such as SDS-plus, and a demolition/chiseling mode for removing tiles or breaking concrete. Some tools in this line offer two-mode operation to switch between drilling and chiseling, which is ideal for versatile job sites.

Maintain by keeping vents clear, using the correct bits for the chuck type, and avoiding dust buildup around moving parts. Ensure your power source matches 220–240 V and never operate on a lower voltage, which can reduce performance. After use, clean any masonry dust from the bit and chuck, and inspect for wear. If your model uses an SDS-plus system, use compatible bits and store the tool with bits removed to preserve chuck integrity.

Pair SDS-plus compatible chisels and drill bits for concrete with models that feature an SDS-plus chuck, or use standard 20 mm bits for units with a straight 20 mm chuck. Include chisel attachments for demolition tasks and cores for deeper masonry work where applicable. Accessories like an auxiliary handle and depth gauge improve control and accuracy, while a dust extraction attachment can help keep the work area cleaner and safer during heavy drilling.

Wear protective eyewear and hearing protection, secure the workpiece firmly, and adopt a two-handed grip for stability. Keep cords away from the operating area and switch off the tool before changing bits. Start at low speed to verify control, then progressively apply pressure. Ensure proper ventilation when drilling masonry to minimize dust and debris inhalation, and pause periodically on long tasks to prevent user fatigue.
