Professional SDS Max Hammer

The Bosch GBH 12-52 DV delivers the highest performance within the manufacturer’s rotary hammer range. This corded power tool features a 1700W motor and 19 Joules of impact energy for demanding concrete work. It handles the toughest drilling and chiseling tasks on industrial job sites.

Built for the Job

This heavy-duty machine serves contractors involved in structural reinforcement, large-scale demolition, and utility installations. It excels when drilling large diameter holes for HVAC ducting or plumbing stacks. The tool provides the necessary torque and impact force to drive core cutters up to 150mm through reinforced concrete walls. Site supervisors rely on this unit for consistent performance during extended shifts where smaller hammers would overheat or fail.

• Drilling through-holes for sanitation pipes and electrical conduits.

• Heavy chiseling for masonry removal and floor tile stripping.

• Installing heavy-duty anchors in bridges and foundations.

On-Site & Workshop Notes

• Always use high-quality SDS max bits to ensure the 19J impact force transfers effectively to the material.

• However, avoid over-greasing as this can attract dust and cause mechanical jams in the tool holder.

• The integrated service display indicates when carbon brush changes are necessary to prevent motor damage.
