Bosch GSR18V-755CB25 18V Brushless 1/2-in Drill/Driver Kit review

This is a desk-based assessment of Bosch’s exact U.S. GSR18V-755CB25 kit page, its directly linked GSR18V-755C/GSB18V-755C operating manual, the observed Bosch catalogue entry and the exact kit image. No ownership, hands-on use or performance testing is claimed.

CB25 is a specific kit around the GSR18V-755C

Bosch identifies the retail configuration as GSR18V-755CB25, with product-page identifier 06019G0112 and separate spare-parts identifier 3601JG0110. The included machine is described as the GSR18V-755C: an 18V EC brushless 1/2-in drill/driver. The CB25 package list names two CORE18V lithium-ion 4.0Ah compact batteries, an 18V charger, auxiliary handle, 4x bit holder, four bits, belt clip and carrying bag. It does not name the exact battery or charger model numbers, and the four bits are not itemized by size or type. Verify the exact suffix and kit contents before comparing offers; the separate GSR/GSB model names signal a functional difference, not a box-content variation.

It is the drill/driver, not the hammer-drill counterpart

The manual linked from this exact Bosch page groups GSR18V-755C with the GSR18V-975C as drill/driver models. Its specification table gives the GSR column no beats per minute and “NA” for masonry drilling, while hammer beats and a masonry limit are listed separately for the GSB models. In its operating instructions, Bosch says hammer-drilling action applies to GSB18V-975C and GSB18V-755C only. This GSR kit is therefore not the choice when integrated hammer action is an essential documented feature. A regular drill may turn an appropriate masonry bit, but that is not the same as a documented hammer-drilling mode; the manual gives no masonry capacity for this GSR version.

Read chuck fit, material limits and speed as separate facts

The exact product page lists an all-metal 1/2-in keyless chuck. The linked manual separately lists maximum capacities of 1/2 in for mild-metal drilling and 3-1/4 in for wood drilling for the GSR family. Those dimensions answer different questions: chuck capacity is about the bit shank the jaws accept, while the manual’s material capacities are manufacturer limits for drilling under its stated instructions. Neither guarantees a particular result in every species of wood, metal alloy, bit geometry or setup. The manual does not give a maximum screw size in the cited table, so the 755 in-lb torque figure should not be converted into a made-up screw rating or expected job result.

Bosch lists two no-load ranges, 0–480 and 0–2,100 rpm, and a 25+1 clutch on the exact page. The manual describes 25 clutch positions whose output torque rises as the ring moves from 1 to 25 and says the tool stops rotating when the selected torque is reached. Its drill-only action locks the clutch for drilling and driving heavier work. That gives the model more setup control than a single-speed, clutch-free arrangement, but settings are not a measured guarantee against damaged fasteners. The manual remains the authority for bit choice, speed, workholding and operating limits.

KickBack Control has limits and an optional connected layer

Bosch describes KickBack Control as reducing the risk from sudden rotational torque reaction in a bind-up. The linked manual explains that a sudden jam can shut the tool off and trigger flashing lights. It also narrows what that feature means: sensitivity is adjustable through the Bosch Toolbox app when the optional GCY42 Connectivity Tool Module is installed; without the module the default applies, and the feature can activate only while the tool is running at maximum speed. The module is listed as an optional compatible accessory, not as an item in this kit’s Includes list. KickBack Control is not a promise that every bind-up is prevented, and it does not replace the manual’s instructions or the included auxiliary handle.

Do not turn the overall length into a short-head claim

Bosch’s technical table gives 7.6 in overall length, 8.4 in height and 3 in width. It does not state a separate tool-head length, so this review does not treat the overall-length field as evidence of a head at or below six inches. For a cabinet recess or space beside a stud, measure the actual approach, hand, battery and bit clearance rather than relying on a body dimension alone. There is also a small but meaningful conflict on weight: the exact page’s technical table says 3.4 lb tool-only, while its further-information paragraph says 3.5 lb tool-only. These are two manufacturer page statements, not independent measurements; no single weight is selected here.

Who may want this configuration—and what to verify

The CB25 package is a plausible shortlist candidate for someone already working in Bosch’s 18V system who wants an included two-battery kit and a documented 1/2-in chuck for general drilling and screwdriving. The auxiliary handle, two selectable speed ranges, clutch and brushless motor are documented features, while the 755 in-lb value is Bosch’s published claim rather than a comparative test result. If your priority is masonry drilling, a sub-six-inch tool head, a known charger model or a precise tool-only weight, this evidence does not answer that need: compare a separately documented hammer drill, obtain a stated head dimension, or verify the exact kit and manual details before buying. The category record still has an unresolved roster count, and this assessment makes no claim about current seller stock, price, condition or availability.

For reference, the exact Bosch GSR18V-755CB25 U.S. page supplies the package list and product-table data; Bosch’s linked operating and safety instructions separate the GSR drill/driver from the GSB hammer-drill operation. Use the manual for final setup and safety decisions.
