Combination Hammer
The Bosch GBH 2-28DV is the ultimate solution for heavy-duty drilling and chiselling in reinforced concrete and structural frames, featuring a high-performance 850W motor, 3.2J impact energy, and advanced SDS-Plus bit system for fast torque transfer and secure retention, while the integrated vibration control system significantly reduces hand fatigue during prolonged use; engineered with rotation stop mode for chiselling, variable speed (0–900 rpm) for material precision, reverse/forward function, and three operating modes in one tool, this compact 2.9 kg hammer combines strength, versatility, and comfort to meet the toughest jobsite demands.
• High-Power 850W Motor: Designed to deliver reliable performance during demanding drilling and chiselling tasks
• 3.2J Impact Energy: Enables fast material penetration and efficient removal in reinforced concrete and dense substrates
• SDS‑Plus Bit System: Ensures fast bit changes with strong torque transfer and stable retention under load
• Advanced Vibration Reduction System: Significantly improves user comfort during prolonged or overhead use
• Rotary Stop Mode: Allows switching to pure chiselling function for demolition or tile removal tasks
• Variable Speed Control (0–900 rpm): Enables smooth starts and precise control across different materials
• Overload Clutch Safety: Automatically stops rotation to prevent user injury if the bit binds or jams
• Forward/Reverse Rotation: Useful for freeing jammed bits and assisting in light screwdriving work
• Three Operating Modes in One Tool: Combines rotary drilling, hammer drilling, and chiselling for maximum flexibility
• Max Drilling Capacities: 28 mm in concrete, 13 mm in metal, and 30 mm in wood — ideal for multi-material applications
• Compact Weight (2.9 kg): Balanced for comfortable handling, even in horizontal or overhead positions
• Rugged Build & Internal Seals: Designed to withstand dust, impact, and site-level stress for long-term reliability
• Heavy-duty concrete drilling
• Wall and floor chiselling for demolition tasks
• Structural renovation and civil engineering works
• Anchor setting and pipe fixing installations
• Electrical, plumbing, and HVAC installations
