The Bosch GSR18V-800CB24 is a cordless drill kit built around a brushless motor that delivers 565 In.-Lbs. of max torque, supplied with (2) CORE18V® 4 Ah batteries.
Bosch sells the kit with one GSR18V-800C tool body, a charger, a belt clip and a storage bag, so the box covers the basics without extra purchases for a first day of use. The tool is also connected-ready, which means it accepts an add-on rather than arriving with that hardware already fitted.
Read the 565 figure carefully: it is a torque rating in inch-pounds, not a speed rating, so it describes twisting force rather than how fast the chuck turns. That distinction is worth settling before comparing this kit with anything else on the shelf.
What Features Does the Bosch GSR18V-800CB24 Offer?
The Bosch GSR18V-800CB24 is a drill/driver on the 18V platform in a 1/2 In. size, classed by Toolup as a Variable Speed Drill and pairing an efficient brushless motor with Advanced Power batteries.
Bosch’s own description calls the motor output impressive and credits the tool with superior user control, so both are manufacturer claims rather than independent test results. Brushless designs avoid brush friction, which is why power delivery and battery life tend to improve together.
Bosch pairs the tool with two 4 Ah packs for optimal productivity and runtime. In my view, a second pack matters more than the headline torque on a long day, because one charges while the other works.
Working backward from the kit, each spec has a job: the 1/2 In. size sets bit capacity, the 18V platform sets which batteries fit, and the motor sets how long a pack lasts.
What Comes in the Bosch GSR18V-800CB24 Kit?
The Bosch GSR18V-800CB24 kit includes one GSR18V-800C tool, two CORE18V 4 Ah batteries, a charger, a belt clip and a storage bag, while the GCY42 connectivity module is sold separately.
Toolup’s listing showcases the contents under Toolup Part # 894595, and the Toolup SKU is GSR18V-800CB24. The table below separates what ships in the box from what does not.
| Item | Included in kit? | Detail |
| Tool | Yes | (1) GSR18V-800C 18V Brushless Connected-Ready 1/2 In. Drill/Driver |
| Batteries | Yes | (2) CORE18V® 4 Ah Advanced Power |
| Charger | Yes | Listed by Toolup as part of the kit |
| Belt clip | Yes | Listed by Toolup as part of the kit |
| Storage bag | Yes | Listed by Toolup as part of the kit |
| Connectivity module | No | GCY42, sold separately |
The module is optional. When fitted, the GCY42 links the tool to the Bosch Toolbox App for enhanced customization options, so a buyer who never plans to use the app can ignore it.
The two batteries belong to the AMPShare 18V Battery System, which Bosch describes as multi-brand compatible, so packs from other brands on that platform may also work with this tool.
What Are the Core Specs of the GSR18V-800CB24?
The Bosch GSR18V-800CB24 specification centers on two speed settings for high-speed and high-torque work, plus 20+1 clutch settings and a switchable precision clutch.
With the clutch switched on, the tool stops as soon as clutch slippage is detected. That is a protective stop rather than a power reduction, which suits screws that should seat without being overdriven.
Bosch also states that its cordless tools are covered by a five-year limited warranty, and the table below splits tool, charger and battery coverage alongside the other figures.
| Spec | Value | Note |
| Speed settings | Two | High-speed and high-torque applications |
| Clutch settings | 20+1 | Precision clutch is switchable |
| Tool and charger warranty | 5 Year Tool/Charger | Limited warranty per Bosch |
| Battery warranty | 3 Year Battery | Limited warranty per Bosch |
| Connectivity | Connected-ready | Optional GCY42 module enables app-based customization |
The sources reviewed give no rpm or weight figures for this model, so those numbers need confirming on Bosch’s spec sheet.
Does the GSR18V-800CB24 Connect to an App?
Yes, the Bosch GSR18V-800CB24 is connected-ready and works with the Bosch Toolbox App once the GCY42 connectivity module, which is sold separately, is fitted.
Connected-ready does not mean connected out of the box. Toolup lists the Drill Type as Variable Speed Drill, and the module is the piece that adds app control. The model is one of the Bosch 18V cordless power tools that carry the five-year limited warranty.
Bosch says the 20+1 clutch settings support driving accuracy and reduced fastener damage, but the sources reviewed do not say which settings the Bosch Toolbox App adjusts. If tuning for drilling or driving matters, confirm that before buying the module.
How Long Is the Warranty, and Which Batteries Fit?
Bosch gives the Bosch GSR18V-800CB24 a five-year limited warranty on the tool and charger and a three-year limited warranty on the batteries, which belong to the AMPShare 18V Battery System.
Warranty length is a manufacturer’s promise, not a durability test, so the all-metal chuck deserves separate attention: Bosch lists it for enhanced durability. That is a design claim, and a buyer should weigh it as one.
Toolup describes the kit as jobsite-ready for demanding jobs, and Bosch labels the model Professional. Both are positioning statements rather than measured results, so the numbers in the specification table carry more weight than the adjectives.
NauticExpo files the tool as a cordless drill screwdriver, which shows how the same hardware gets categorized differently across catalogs.
Where Does This Drill/Driver Earn Its Keep on the Jobsite?
The Bosch GSR18V-800CB24 suits general drilling and driving work, from framing and panel jobs to marine shops.
Bosch’s product images and catalog listings point to three settings:
- Wooden frame: one image shows a gloved user screwing into one.
- Electrical panel: another image shows the tool in use on one.
- Boatyards and shipyards: NauticExpo lists the tool for this kind of marine work.
The same images mention settings for 1/16-1/2 inch drill bits, which matches the 1/2 In. size. Marine use deserves a caution: the sources do not describe any water or salt protection, so check before relying on it there.
KickBack Control reduces the risk of a sudden rotational torque reaction in a bind-up scenario, such as a bit jamming in a frame member. The integrated LED worklight lights the working area for better visibility, which helps inside a panel box.
The ergonomic design promotes comfort and balance, and those qualities matter most late in a shift, when fatigue shows up as sloppy alignment.
