Bosch GDR18V-1800CN Brushless Connected-Ready Impact Driver
I’m a huge fan of Bosch’s Freak with its hybrid 1/2″ square and 1/4″ hex drive. The only downside is that it’s a big long compared to other Pro impact drivers. That’s not a problem with the Bosch GDR18V-1800CN. It has the same muscle as the Connected-ready Freak in a more compact size without the hybrid drive.

Bosch GDR18V-1800CN At a Glance
Power and Speed
The standard Bosch brushless impact driver has almost identical specifications to the updated Freak, telling us that they’re likely using the same motor in both. It has 3 speed modes to work with, hitting 1100, 2300, and 3400 RPM under load. Of course, the trigger is variable speed, so you can feather those.
It’s also boasting 1800 in-lbs of torque. While that’s pretty far down from the top models that spec 2250 in-lbs, it’s plenty. One of the things we learned in our impact driver shootout is that once you get over that 1600–1800 in-lbs range, you start breaking socket adapters pretty quickly. When it comes to driving screws, higher speeds and impact rates are better than crazy-high torque.
Speaking of impact rate, that’s the one area the Bosch GDR18V-1800CN and the Connected Freak are slightly different. This impact driver hits 4000 times per minute, while the Freak is slightly higher at 4200 IPM.
The biggest deal for this Bosch brushless impact driver’s feature set is that it’s Connected-ready. That’s what the “CN” in the model number indicates. By adding a Bosch Connected Module in the access point on the handle, you can turn it into a smart tool. Bosch’s free app connects via Bluetooth to give you some tracking (using Bosch Bluehound) and diagnostics along with some customization options.
Size and Weight
This is the Bosch impact driver you want to go for when compact size trumps the benefits of a hybrid drive system. Both impact drivers are 8.2″ tall, but the Bosch GDR18V-1800CN cuts the head length down to 4.9″. That’s nearly a full inch less than the Freak.
The weight is only marginally lower at 2.4 pounds. You save a few ounces, but it’s not so much that it will change your life.
You have a couple of options to get your hands on this Bosch brushless impact driver. The Bosch GDR18V-1800CN is the bare tool and runs $139. A kit with two 4.0Ah Core18V batteries and a charger is $289. You can find that one under the model Bosch GDR18V-1800CB25.
If you’re looking for a combo kit, the Bosch GXL18V-238B25 includes the impact driver and GSR18V-535C Connected-ready compact drill driver. Check out our review of the hammer drill version here. With two Core18V 4.0Ah batteries and a charger, it runs $299. You’re essentially adding the drill driver for $10, making it a pretty sweet deal.

The Bottom Line
While the Bosch Freak is a great choice when you have plenty of space to work in, the Bosch GDR18V-1800CN brushless Connected-ready impact driver gives you the same muscle in a more compact package. For installers, electricians, remodelers, and anyone else that uses impact drivers in tight space, it’s the way to go.
