Bosch GSB18V-755CN 18V EC Brushless Connected-Ready Brute Tough 1/2-in Hammer Drill/Driver (Bare Tool) review

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

GSB18V-755CN identifies the bare-tool package

Do not confuse the retail suffix with the core tool name. Bosch's exact product route identifies GSB18V-755CN under page identifier 06019G0310 and gives 3601JG0310 as its separate part number. Its written Includes list names one GSB18V-755C 18V hammer drill/driver, an auxiliary handle, a 4x bit holder, four bits and a belt clip. Bosch says battery and charger are sold separately. The four bits' sizes and types are not specified, so this list does not establish that a particular masonry, wood or metal bit is supplied.

The page-linked image shows the 755C body with a side handle and belt clip, consistent with the written list. The list, rather than a package photograph, establishes the contents. This review therefore treats the CN as a bare-tool SKU with included handling/accessory pieces, not as a drill with a battery pack in the box. A Bosch 18V owner should still verify the exact battery and charger instructions; the public finder has no Bosch 18V platform choice and cannot confirm pack compatibility.

The manual distinguishes this GSB from the GSR drill/driver

Bosch describes a brushless, connected-ready Brute Tough hammer drill with a 1/2-in all-metal keyless chuck, variable speed, reverse, a 25+1 precision clutch, KickBack Control and electronic motor/cell protection. The linked manual identifies GSB18V-755C separately from GSR18V-755C. Its GSB column documents hammer action at up to 31,500 beats per minute; the nearby GSR column has no hammer beats and no hammer-drilling mode. Similar numbers and the same 755C family do not make the two bodies interchangeable in a finder result. The CN package is the GSB, not a GSR kit.

The manual lists two no-load speed ranges, 0–480 and 0–2,100 rpm, and 25 adjustable clutch settings. The separate drill setting and hammer mode serve different purposes: the manual explains that hammer action overrides the clutch. Bosch's maximum torque claim is 755 in-lb. Torque, impact rate and no-load speed are manufacturer specifications, not independently measured performance, loaded speed, runtime or proof of an achievable hole in a given workpiece.

Capacity figures are material-specific maker limits

For the GSB18V-755C row, the manual lists maximum capacities of 3-1/4 in for wood, 1/2 in for mild metal and 5/8 in for masonry. These values refer to different materials and should not be collapsed into one universal drilling diameter. The 1/2-in chuck is the bit-shank capacity, not a promise that the drill will produce a 1/2-in hole through every material. Use the correct bit, mode, speed, support and safety procedure in the manual; Bosch's listed maxima are not independent test results or a guarantee for every material, bit, battery or operator.

The manual says to support the tool with its auxiliary handle during operation. Here that handle appears in the CN written Includes list, a useful difference from certain other Bosch CN packages where an illustrated handle is not listed. Confirm that the handle is present and correctly attached before work. KickBack Control is described as reducing risk from sudden rotational reaction in a bind-up; it does not prevent every bind or replace a firm grip, safe body position or the manual's precautions.

Overall length does not answer a short-head question

Bosch's technical table lists a 7.6-in product length, 8.4-in height, 3-in width and 3.5-lb tool-only weight. The page does not separately state tool-head length. Thus, the 7.6-in overall dimension cannot establish the finder condition of a manufacturer-stated head length at or below 6 in. Nor would a short bare head by itself prove clearance once a battery, handle, bit, hand and approach angle are considered. Check the actual drilling position rather than using catalog length as a clearance guarantee.

The same page advertises optional GCY42 connectivity and compatibility with the HDC200 dust hood. Neither accessory appears in the written CN Includes list. Treat both as separate accessories, and confirm their exact compatibility and instructions if needed. The page names the Bosch Toolbox app in its connected-tool description; connectivity is optional rather than part of the bare-tool box.

Who should compare this configuration?

The GSB18V-755CN is a relevant candidate for someone intentionally buying a tool-only Bosch 18V hammer drill with a documented 1/2-in chuck and included auxiliary handle. Its package is meaningfully different from the GSB18V-755CB25 kit: the kit page lists two 4.0Ah compact batteries, an 18V charger and a carrying bag, whereas this CN page marks battery and charger not included. These are package differences, not distinct claims about drilling performance. Compare the exact retail suffix and written Includes list before ordering; do not substitute the kit image or GSR18V-755C drill/driver information for this CN hammer-drill body.

The saved Bosch U.S. safety-index capture from 2026-10-31 displayed a 1380SLIM grinder notice and no visible GSB18V-755CN or GSB18V-755C notice. That is a limited dated page check, not safety certification or a promise that no later notice will appear. This assessment does not state current retailer stock, price, seller condition or availability.
