Rotary hammer Bosch PBH 2100 RE 550 W SDS Plus — 550W, 1.7 J impact, 2300 RPM, 20 mm concrete drill

The Bosch PBH 2100 RE is a corded SDS Plus rotary hammer designed for drilling and light chiselling in masonry and concrete. With an input power of 550 W, an impact energy of 1.7 J and a no-load speed up to 2300 RPM, the tool is intended for renovation, installation and general DIY tasks where a compact, easy-to-handle hammer drill is required. It supports concrete drilling up to 20 mm and offers the basic functions needed for fastening, drilling and occasional light chipping.

Advantages

The compact design and moderate weight make the Bosch PBH 2100 RE easy to handle for overhead work and prolonged use. The SDS Plus chuck system enables quick, tool-free bit changes and secure retention of drill and chisel bits. With a combination of 550 W input power and 1.7 J impact energy the tool balances drilling speed and impact performance for common masonry tasks while maintaining a small footprint suitable for tight spaces.

Suitable for

• Drilling holes in concrete, brick and masonry up to 20 mm diameter
• Installing fixtures, plugs and anchors in walls for renovation and mounting
• Light chiselling and removal of tiles or mortar in occasional repair jobs
• DIY projects where a compact corded rotary hammer is preferable to a larger demolition hammer

When it may not be suitable

This rotary hammer is not intended for heavy demolition or continuous industrial use; its impact energy (1.7 J) and power class are designed for light to medium tasks. For large-scale breaking, wide channelling or long-duration professional masonry work, a higher-powered demolition hammer would be more appropriate. Noise and vibration levels are typical for tools in this class and may require protective equipment during extended operation.

Key specifications

• Input power: 550 W
• Impact energy: 1.7 J
• No-load speed: up to 2300 RPM
• Drilling capacity in concrete: up to 20 mm
• Chuck system: SDS Plus
• Primary functions: rotary drilling, hammer drilling, light chiselling

How to use

Select an appropriate SDS Plus drill or chisel bit for the task and insert it into the chuck until it locks. Choose the required mode (rotation only, hammer drilling or chiselling) using the tool’s mode selector. When drilling into concrete, mark the drilling point, start at low speed to position the bit and then proceed with steady pressure, allowing the tool’s impact action to do the work. For chiselling, secure the workpiece and use controlled, steady movements. Always disconnect the tool from the mains before changing bits or performing maintenance.

What to consider before purchase

• Confirm that 20 mm drilling capacity meets the largest hole size you require for anchors or fixtures
• Assess whether 1.7 J impact energy is sufficient for your planned chiselling or demolition tasks
• Decide if a corded tool with 550 W input power matches the intended usage and site power availability
• Ensure SDS Plus bits and accessories are compatible and available for your projects

Usage recommendations

Use eye protection, hearing protection and dust extraction or a mask when drilling or chiselling masonry. For repetitive or prolonged work, take regular breaks and maintain a firm, two-handed grip. Store SDS Plus bits cleanly and inspect the tool power cord and ventilation slots before each use to ensure safe operation.
