Bosch GBH 8-45 DV SDS Max Rotary Hammer, 1500W, 12.5J

Bosch GBH 8-45 DV Rotary Hammer

The Bosch GBH 8-45 DV delivers high-performance drilling and chiseling capabilities for heavy-duty construction environments. This 1500W SDS Max tool provides 12.5 Joules of impact energy to handle reinforced concrete and masonry. It features a triple vibration damping system to protect operators during extended use on structural job sites.

Built for the Job

Site supervisors and concrete contractors utilize this heavy-duty hammer for demanding structural work. The motor provides consistent power even under heavy load, making it suitable for drilling large diameter holes for service entries or chemical anchors. The integrated Turbo Power function utilizes the energy otherwise used for rotation to increase impact force during chiseling tasks. This ensures faster material removal when stripping screed or chasing walls for plumbing and electrical installations. The robust metal components and high-grade housing withstand the rigors of daily site handling and transport.

• Drilling through-holes for large diameter piping and ventilation ducts.

• Heavy-duty chiseling and demolition of masonry or concrete structures.

• Setting large diameter mechanical and chemical anchors in structural footings.

Product Highlights

Vibration Control System

The triple-action damping mechanism significantly reduces hand-arm vibration levels to 7 m/s² during chiseling.

Safety and Durability

• Overload clutch protects the operator if the bit jams in reinforced steel.
• Automatic switch lock maintains continuous chiseling without manual trigger pressure.
• Restart protection prevents the motor from starting automatically after a power cut.
