Designed for Professional Use
The Bosch GBH 18V-21 Cordless Rotary Hammer is built for job sites that demand consistent power and long-term durability. It’s part of Bosch’s Professional 18V System, which means it integrates seamlessly with all Bosch 18V batteries and chargers.
Its powerful rotary hammer mechanism offers a maximum impact energy of 2 joules, making it suitable for a wide range of materials and tasks. From drilling into reinforced concrete to light chiseling jobs, this tool delivers optimal performance every time.
Three Modes for Maximum Versatility
One of the most useful features of the GBH 18V-21 is its three-mode operation:
-
Rotary drilling – for wood, metal, and plastic
-
Hammer drilling – for concrete and masonry
-
Chiselling – for light demolition and surface work
This multifunction capability allows you to switch between different tasks without changing tools. As a result, your workflow remains uninterrupted and highly productive.
Cordless Freedom with Bosch 18V System
Cordless tools provide unmatched convenience and flexibility, especially on large sites or remote jobs. As part of the Bosch Professional 18V System, the GBH 18V-21 offers true cordless freedom without compromising on performance. It runs on Bosch’s powerful 18V lithium-ion batteries (sold separately), giving you:
-
Consistent power output
-
Extended runtime
-
Quick recharge with compatible chargers
-
Cross-compatibility with other Bosch 18V tools
Because this model is sold as body only in a carton, it’s a perfect addition for users who already own Bosch 18V batteries.
Ergonomic and Compact for Comfortable Handling
Despite its strength, the GBH 18V-21 is surprisingly compact and well-balanced. Bosch has designed this tool with user comfort in mind. Its ergonomic grip, low vibration, and compact body ensure fatigue-free operation even during extended use.
Working overhead, in tight corners, or in hard-to-reach areas becomes easier thanks to its balanced design and lightweight construction. This makes it a smart choice for electricians, plumbers, and contractors who work in varied environments.
High Durability and Long Service Life
Professional tools must withstand daily wear and tear. That’s why the GBH 18V-21 features robust internal components and a dust-protected housing that extends the lifespan of the tool. It’s designed to operate reliably under harsh jobsite conditions.
The brushless motor technology used in this model reduces internal friction, which not only enhances runtime but also lowers maintenance needs. As a result, users benefit from a longer tool life and better return on investment.
Optimised Performance in Concrete and Beyond
With up to 2 J of impact energy, the GBH 18V-21 excels at drilling holes into concrete up to 21mm in diameter. This makes it ideal for tasks such as:
-
Installing anchors and fixings
-
Mounting cable conduits
-
Removing tiles and light chipping
-
Chiselling small sections of plaster or brickwork
It also handles drilling in wood and steel efficiently, making it a well-rounded tool suitable for many types of construction or installation work.
LED Work Light for Better Visibility
Poor lighting is no longer a problem, thanks to the integrated LED work light. It illuminates your working surface clearly, especially helpful in dark spaces like basements, ceiling voids, or underfloor areas.
Better visibility leads to more accurate drilling and a safer, more productive workflow. This feature is another reason why this tool is trusted by professionals.
Supplied in a Sturdy Carton for Safe Storage
Although batteries and chargers are not included, this model is delivered in a durable carton box that provides basic protection and easy transport. If you’re already invested in the Bosch ecosystem, this body-only version offers better value and less waste.
You can also upgrade to Bosch’s dedicated L-BOXX system for advanced tool storage and transport options, ensuring your tools stay safe and organised at all times.
