Bosch GBH 18V-EC 18V SDS+ Cordless Hammer Drill

Bosch GBH18V-EC

The lightest SDS+ cordless rotary hammer drill you've ever used?

That's what one plumber concluded after testing the Bosch GBH 18V-EC 18V Li-ion SDS Plus Cordless Rotary Hammer Drill with Brushless Motor (click the link for full spec and our best price) for our video review, which you can watch below.

However, does being as "lightweight", as described by Wayne Burgess of Avalon Building, mean that the Bosch GBH18V-EC is a lightweight performer?

Read on in our review to find out. We also cover the main benefits of owning the GBH18V-EC.

Bosch has engineered the GBH18V-EC around a brushless motor.

Brushless motors are more efficient, are small, run cooler and last longer. Get the full story on how going brushless could significantly help you at work via our guide here.

The brushless motor in the GBH18V-EC will help your cordless batteries run longer per charge (note: Bosch refer to these motor types as "EC" or Electronically Commuated. Click here for our video guide).

And considering that the GBH18V-EC can run off  Bosch's CoolPack batteries (click for our article on these), packing in 4.0Ah per battery, the tool provides a surprisingly powerful punch, considering its size.

Impact Energy
Drilling in Steel
Drilling in Wood
Drilling Concrete
Max. 13mm
Max. 20mm
4 - 18mm depending on the bit
0 - 1400rpm
0 - 4550bpm

All of that power, via its 3-modes, in a package weighing in at only 2.6kg. This could be the ideal drill for anyone who needs to work at - or above - shoulder height for long periods of time.

Coupled with the brushless motor and high capacity li-ion batteries are the lovely bits and pieces of technology that the boffins at Bosch love to pack into their power tools.

For example, Electronic Cell Protection.

Along with the CoolPack feature on the 4.0ah batteries, which translates into longer runtimes from the batteries as the cells stay cooler for longer, ECP protects the li-ion batteries from overload and deep discharge, both of which serious impare their efficiency.

And then there's Electronic Motor Protection.

This shuts down the motor in the event that you accidently overload it. It also protects the motor within the tool should you, again by accident, drop it from a height of up to 2m (even onto concrete).

So the GBH18V-EC is light, compact, powerful and pretty robust.

What about performance?

Looking at the table above should show you that the tool is going to be able to handle perhaps a little more than you'd expect one of this size to be able to.

Bosch also claims that it has the highest chiselling removal rate (12 kg/hour) in its class. This seemed to surprise Wayne's colleague Neil Bradbury in this Bosch video on YouTube:

Is the GBH18V-EC a lightweight performer?

So, we were glad to have the chance to visit Wayne at his workshop in Lancashire and we asked him his thoughts on the Bosch GBH18V-EC and also whether he'd make it feel some pain for us.

Here's his review video on Toolstop TV (click the link or watch in the player below):

So, what do you think of the Bosch GBH18V-EC SDS+ 3-mode rotary hammer? Are you impressed by:

  • its compact size and low weight
  • its power and robustness
  • its intelligent motor and batteries
