One Chuck, Three Bit Types: Meet the Bosch GBH18V-18X Rotary Hammer

Rotary hammers are great for drilling into concrete. The thing is, most of them are built around a single bit type, forcing you to grab another drill once the material changes.

Bosch just made that process much easier.

The new Bosch GBH18V-18X Professional Rotary Hammer features the versatile ONECHUCK system. This single chuck accepts SDS-plus, cylindrical and 1/4-inch hex-shank bits, allowing you to move between different materials without switching tools.

For contractors who regularly work with concrete, wood, and metal, that versatility could make this rotary hammer the game-changer you have been waiting for.

The chuck is easily the headline feature. SDS-plus bits are used for hammer-drilling into concrete, while cylindrical bits give you the ability to drill into materials such as wood and metal. The chuck also accepts compatible 1/4-inch hex-shank bits.

Instead of carrying one rotary hammer for concrete and another drill for everything else, you can complete more applications with one compact cordless tool.

That makes the GBH18V-18X especially useful for electricians, plumbers, HVAC technicians, remodelers and general contractors. These trades rarely work with one material all day. A single installation might require drilling through concrete, wood framing and metal supports. ONECHUCK helps you adapt without constantly heading back to the toolbox.

Bosch designed this rotary hammer around an efficient brushless motor that maintains consistent speed and power during continuous work. It provides the performance needed for professional drilling applications while keeping the tool compact and manageable.

Its compact and lightweight design makes the tool easier to control in confined spaces, overhead applications and longer drilling sessions. Bosch optimized the rotary hammer for use with a compact 2.0Ah battery, helping keep the overall setup light and maneuverable.

An integrated LED light will illuminate the immediate work area, which is nice for when you’re drilling inside cabinets, mechanical rooms, basements and other poorly lit spaces.

Rotary hammers can create a sudden rotational force when a bit jams in the material. Bosch’s KickBack Control can react during a bind-up situation, helping reduce the risk of unexpected tool rotation.

The tool also includes Vibration Control, which helps reduce the vibration transferred to the operator. That added comfort can make a noticeable difference when drilling multiple holes or using the tool for longer periods.

These features do not replace proper technique or personal protective equipment, but they add another level of control to a powerful cordless tool.

The GBH18V-18X makes the most sense for professionals who regularly move between different drilling applications.

It can be used for:

1. Drilling holes for anchors in concrete
2. Running plumbing, conduit or wiring through multiple materials
3. Drilling into wood framing and metal components
4. Completing overhead or confined-space installations
5. Handling maintenance and renovation work without constantly changing tools

It is also a smart option for anyone already using Bosch 18V batteries. As part of the AMPShare system, the rotary hammer works with compatible Bosch 18V batteries and a growing selection of cordless products from participating AMPShare brands.

The biggest selling point here is simple: versatility.

You get the concrete-busting power of an SDS-plus rotary hammer, but you can also slap in cylindrical and 1/4-inch hex bits. Throw in the compact brushless build, KickBack Control, Vibration Control, and AMPShare compatibility, and you’ve got a tool that’s ready for whatever the workday throws at you.

It is also available in the GBH18V-18XB22 kit, giving professionals a convenient kit option when it is time to upgrade.

Bosch backs its 18V cordless power tools with a five-year limited warranty. Warranty terms and additional details are available through Bosch’s power-tool warranty information.

If your current rotary hammer only comes out for concrete, the GBH18V-18X gives you a reason to keep one tool within reach for much more of the job.

What types of bits does the Bosch GBH18V-18X accept?

Its ONECHUCK system accepts SDS-plus, cylindrical and compatible 1/4-inch hex-shank bits. This allows the rotary hammer to handle a wider range of drilling applications without requiring a separate chuck.

What materials can the GBH18V-18X drill?

With the appropriate bit, it can hammer-drill into concrete or perform standard drilling applications in wood and metal.

What does KickBack Control do?

KickBack Control can react when the bit suddenly binds, helping reduce the risk of unexpected tool rotation. It does not eliminate every kickback risk, so proper handling and personal protective equipment are still necessary.

How does Vibration Control help the operator?

Vibration Control helps reduce the vibration transferred from the tool to the user. This can improve comfort during repetitive drilling and longer work sessions.

Which batteries work with this rotary hammer?

The GBH18V-18X works with compatible Bosch 18V and AMPShare system batteries. Bosch optimized its compact design for use with a 2.0Ah battery. The rotary hammer is also available as the GBH18V-18XB22 kit.
