How to use

Select an appropriate SDS Max drill bit or chisel for the task and secure it in the chuck according to the manufacturer's instructions. Mark the drilling location and use appropriate personal protective equipment, including eye and ear protection and dust control measures. Start the tool at low speed to position the bit, then operate at the recommended speed and feed pressure for the material being worked. For chiselling, set the tool to the hammer-only or chisel mode if available and maintain steady control to guide the tool along the required surface. Allow the tool to cool periodically during extended use and inspect the bit for wear to ensure consistent performance.

Recommendations

Use the Bosch GBH 12-52 DV Professional in conjunction with dust extraction or wet-suppression systems when working in enclosed or dust-prone environments. Match drill bit quality to the application and replace worn bits promptly. For repetitive heavy-duty tasks, schedule regular maintenance checks and follow the manufacturer’s service intervals to maintain impact energy and motor performance.
