Bosch GSB18V-755CB25 18V EC Brushless Connected-Ready Brute Tough 1/2-in Hammer Drill/Driver Kit with Two CORE18V 4.0Ah Compact Batteries review

This is an independent desk-based assessment of Bosch's exact U.S. GSB18V-755CB25 page, its written package list, the directly linked GSB/GSR family manual, the captured category listing and the kit image linked from that page. No ownership, hands-on use, independent testing or measured performance is claimed.

CB25 is the battery-and-charger kit, not the CN bare tool

Bosch's exact page identifies the GSB18V-755CB25 retail package at page identifier 06019G0312 and lists 3601JG0310 as a separate part number. The included body is named GSB18V-755C. Bosch's written Includes list specifies two 18V CORE18V lithium-ion 4.0Ah compact batteries, one 18V charger, one auxiliary handle, a 4x bit holder, four bits, a belt clip and a carrying bag. The bit sizes and types and exact battery/charger model numbers are not named, so check those details if a specific accessory or pack is important.

This package must remain distinct from GSB18V-755CN. The CN page is a bare tool and lists no battery or charger; this CB25 page marks both included. Both share the GSB18V-755C core hammer drill, but they are different purchases with different supplied equipment. The exact CB25 image visually shows the drill, two battery packs, charger and bag; the written Includes line, not the picture, determines that the batteries are the CORE18V 4.0Ah compact type and that the full package includes the stated accessories.

GSB indicates hammer mode; the neighboring GSR is different

Bosch describes this as an 18V EC brushless connected-ready Brute Tough hammer drill/driver, with an all-metal 1/2-in keyless chuck, 25+1 precision clutch, variable speed and KickBack Control. The page lists up to 755 in-lb torque and 0–31,500 beats per minute. The linked manual's GSB18V-755C column documents hammer action, with 0–480 and 0–2,100 rpm no-load ranges. Its GSR18V-755C column is a different drill/driver arrangement without hammer mode. Do not transfer GSB hammer action to the GSR kit just because both carry a 755C designation.

The manual's 25 clutch positions are separate from its drill-only and hammer-drilling modes. It explains that hammer action overrides the clutch. The torque and no-load rpm/BPM figures are Bosch-published specifications, not independent measurements, loaded speeds, runtime estimates, or guaranteed work rates. KickBack Control is described as reducing risk from sudden rotation in a bind-up; it is not a guarantee against kickback or a substitute for using the manual-required auxiliary handle and safe work practices. Bosch lists that handle in this kit's written package contents.

Read the model-specific capacity row carefully

For GSB18V-755C, the linked manual lists 3-1/4 in maximum in wood, 1/2 in in mild metal and 5/8 in in masonry. These are material-specific maximum values supplied by Bosch, not a single universal capacity and not a promise that every hole can be made with every bit, battery, material or position. The chuck's 1/2-in specification refers to shank capacity; it does not mean this drill makes 1/2-in holes in all materials. Select a suitable bit and mode and follow the manual's material, support and safety directions.

On the package side, the 4.0Ah capacity is specified for each of the two listed CORE18V compact batteries; Bosch does not publish their separate model numbers on this page. The charger is simply named as an 18V charger, without its model number. Verify the exact box and any replacement battery/charger compatibility rather than inferring it from a kit photo or from the common Bosch branding.

Dimensions, accessories and limits

Bosch lists tool-only weight at 3.5 lb, length at 7.6 in, height at 8.4 in and width at 3 in. The product page does not give a separate tool-head length. As a result, this assessment does not classify the CB25 as having a manufacturer-confirmed head at or below the quiz's 6-in threshold. Overall length is not the front-of-head measurement and cannot tell whether the complete drill, handle, battery, bit and hand fit a cramped location. Confirm the actual work envelope, bit reach and operator clearance.

The page lists optional GCY42 connectivity and compatibility with the HDC200 dust collection hood; neither appears in the written package list. These are not included by default. The page also describes electronic motor and cell protection. Those advertised features do not establish that the kit prevents overload, overheating or a bind in every use. This desk assessment makes no claim about independent durability or real-world drilling results.

Choosing between the two exact 755 package suffixes

The CB25 configuration makes sense to compare when the buyer wants a documented battery-included Bosch 18V hammer-drill package with two 4.0Ah compact packs, an 18V charger, carrying bag and supplied auxiliary handle. Someone who already owns a compatible pack and charger and wants the bare tool should compare the separate GSB18V-755CN instead. Neither package's inclusion list proves that a particular battery or charger model is compatible with an existing set; check the tool manual and package details. Also distinguish these two hammer drills from the GSR18V-755C drill/driver family: the manual assigns hammer action to GSB, not GSR.

The saved Bosch U.S. safety-index capture dated 2026-10-31 displayed a 1380SLIM grinder notice and no visible GSB18V-755CB25 or GSB18V-755C notice. It is a bounded, dated lookup rather than safety certification or a guarantee about future notices. No current retail price, stock, seller quality, offer or condition is asserted here.

Consult Bosch's exact GSB18V-755CB25 page for the package list and product table, and its linked GSR/GSB18V-755C and 975C manual for the model-specific operating modes, capacity values and auxiliary-handle directions.
