Bosch GBH 12 52 DV SDS Max Rotary Hammer Drill

The Bosch GBH 12 52 DV is a heavy-duty corded SDS Max rotary hammer drill delivering 19 J of impact energy, designed for demanding drilling and chiselling in concrete and stone.

Sitting at the top of Bosch's SDS Max corded rotary hammer range, this machine is built around a high-end 1,700 W motor that drives an impact rate of up to 2,100 bpm. The variable speed control spans 105–215 rpm, giving operators precise command across a wide range of applications. Robust metal components throughout contribute to the tool's long-term durability on site.

Intended for hammer drilling from 12–52 mm diameter in concrete — with an optimal range of 30–50 mm — it also accepts core cutters up to 150 mm and 80 mm breakthrough drill bits. Compatibility with various dust extraction attachments makes it suitable for COSHH-conscious working environments. The wide application range covers construction, landscaping, electrical installation, and plumbing and heating trades.

Safety and operator welfare are addressed through an integrated Rotation Control Clutch, Restart Protection, and Vibration Control. Measured vibration levels of 10.0 m/s² during drilling and 8.0 m/s² during chiselling should be factored into HAV exposure calculations in line with HSE guidelines. Constant Speed and Speed Selection allow the tool to be matched precisely to the task at hand.

Features and Benefits:
• 19 J of impact energy for heavy chiselling in concrete and masonry
