Bosch Professional 611332170 SDS Plus Rotary Hammer GBH 4-32 DFR

Core specs include a 900 W motor, delivering 4.2 joules of impact energy, SDS Plus tool holder for quick bit changes, and three operating modes: drilling, hammer drilling, and chiseling. It also features Bosch Vibration Control, an ergonomic soft grip, and Constant Electronic Speed Control for consistent performance under load.

SDS Plus allows for quick, tool-free bit changes. You can swap bits and chisels rapidly without needing separate tools, helping you maintain workflow on the job site.

Vibration Control reduces operator fatigue by dampening vibration, which can help you work longer with greater comfort and less strain—especially during extended drilling or chiseling sessions.

Use the mode selector to choose the desired function: drilling, hammer drilling, or chiseling. Make sure the tool is unplugged or powered off when you change modes, then power it on to start in your chosen mode.

Wear safety glasses or a face shield, hearing protection, and a dust mask. Wear snug clothing and gloves, secure the workpiece, and keep both hands on the tool during operation. Inspect bits and the cord (if corded) before use and follow general electrical safety practices.

Yes. This model is compatible with dust extraction setups. Pair it with a suitable vacuum or dust-collection attachment designed for SDS Plus tools to keep the worksite cleaner and improve visibility.

Use Bosch SDS Plus bits and chisels designed for SDS Plus systems. For best results and compatibility, stick to original Bosch accessories or other high-quality SDS Plus bits specifically rated for this tool.

Common uses include drilling anchor holes into concrete, creating passages for wiring or plumbing, performing light demolition or chiseling tasks, and removing mortar or tile residues in masonry projects.

Keep the tool clean and free of dust after use, inspect the power cord (if corded) and switches for wear, and store it in a dry place. Periodic checks of bits for wear and proper SDS Plus engagement will help maintain performance.

Compared with the Bosch GBH 4-32 DFV and the Bosch GBH 3-28 DFV, this GBH 4-32 DFR offers robust impact energy (4.2 J) and the benefits of Vibration Control with SDS Plus fast-change capability. If you’re deciding among these, consider highest impact energy and vibration management for tougher concrete work, versus lighter-duty variants.
