Bosch PRO GBH 2-21 Electric SDS Hammer Drill 240V

Overview

The Bosch PRO GBH 2-21 is a compact, entry-level professional rotary hammer featuring SDS-plus technology. Delivering a powerful 2.0 Joules of impact energy from a 720W motor, it easily drills concrete up to 22mm. With three dedicated modes for drilling, hammer drilling, and chiselling, it brings true Bosch performance within reach.

How it works

Using the Bosch GBH 2-21 is incredibly straightforward. Simply pull back the sleeve on the SDS-plus chuck and push your drill bit in until it clicks securely into place. Next, turn the side selector dial to choose your required mode—standard drilling, hammer drilling, or chiselling. Once you are lined up with your mark, squeeze the trigger and apply gentle pressure. The powerful internal pneumatic mechanism does all the heavy hitting, driving the bit effortlessly into solid concrete while you simply guide the tool.

What's in the box

Professional Power in a Compact Package

When you are tasked with drilling anchor holes into solid concrete, standard rotary friction simply will not cut it. The drill bit just bounces off the aggregate, leaving you exhausted.

This Bosch SDS drill utilizes a robust 720W motor delivering 2.0 Joules of pneumatic impact force. This means the internal hammer mechanism does the hard work for you, letting you guide the bit smoothly up to 22mm deep in solid concrete.

Three Modes for Total Versatility

Carrying multiple specialized drills around a site is exhausting and inefficient. The GBH 2-21 gives you three distinct operating modes in one highly compact unit.

With a simple twist of a dial, you can switch between standard drilling for wood, hammer drilling for tough masonry, and a dedicated chiselling mode. This makes it incredibly easy to quickly chip off old ceramic tiles or chase out mortar joints.

Built for Professional Comfort

Heavy, unbalanced SDS drills can easily ruin your shoulders, especially when drilling overhead anchors. Bosch engineered this model to be brilliantly lightweight and ergonomic, significantly reducing operator fatigue.

The included auxiliary handle provides excellent two-handed control, while the depth gauge ensures every single hole you drill is perfectly consistent. This prevents over-drilling and ensures your rawlplugs or anchors seat correctly every time.

Jobsite Ready Out of the Box

Dust is a major health hazard when drilling masonry indoors. To combat this, the GBH 2-21 is fully compatible with professional Bosch GDE dust attachments (like the GDE 16 plus), helping you keep your site clean and fully compliant.

Supplied in a rugged carrying case it's ready to tackle heavy-duty tasks the second you open it. It is the ideal, reliable entry-level solution for any serious tradesperson.
