Bosch GBH 8 45 DV SDS Max Rotary Hammer Drill

The Bosch GBH 8-45 DV is a professional-grade SDS max rotary hammer drill designed for demanding drilling and chiselling work in concrete and stone. Delivering 12.5 J of impact energy from a 1,500 W motor, it handles hammer drill bits from 12 mm up to 45 mm in diameter, along with breakthrough drilling at 80 mm and core cutting from 125 mm.

Bosch's Vibration Control system reduces operator fatigue during prolonged use — a significant advantage when working on time-intensive construction, plumbing, or groundworks applications. The variable impact rate of 1,475 to 2,700 bpm, combined with variable speed selection (165 to 300 rpm), gives the operator precise control across a wide range of materials and hole sizes.

Additional safety and control features include a Rotation Control Clutch, Restart Protection, and Constant Speed under load. The tool is compatible with various dust extraction attachments, supporting compliance with site dust management requirements. Robust metal components throughout contribute to long-term durability in professional use.
