GBH 4-32 DFR Rotary Hammer
The Bosch GBH 4-32 DFR is a high-performance corded rotary hammer engineered for heavy-duty drilling and light chiseling in masonry, concrete, and steel. This 900W professional tool delivers 4.2 Joules of impact energy. It utilizes an SDS plus tool holder with a quick-change system for maximum job-site versatility.
Built for the Job
Contractors use this rotary hammer for high-volume anchoring, through-hole drilling, and medium-scale demolition work. It fills the gap between standard 2kg hammers and heavy 5kg SDS Max units. The robust aluminum gear housing provides superior heat dissipation during continuous high-load operations. Site supervisors specify this model for installing chemical anchors and large-diameter rebar connections where speed is critical. The vibration damping system reduces user fatigue during full-shift operations. Its compact design allows for easier handling in tight spaces compared to larger vertical motor hammers.
-
Drilling 12mm to 32mm holes in reinforced concrete for structural anchors.
-
Core cutting up to 90mm in brickwork for electrical and plumbing runs.
-
Light chiseling and tile removal during renovation and surface prep.
