The Bosch GBH 6-42 C is a brushless SDS max rotary hammer that puts control features first. Along with a 1,300 W motor, it lists a safety clutch, KickBack Control, Vibration Control and a new user interface for choosing work modes that also links to an app. It suits trades and contractors who want the most protective feature set available in an SDS max hammer.

In its favour
- The listing states a brushless motor with an automatic drive rotation system.
- A safety clutch, KickBack Control and Vibration Control are all listed.
- A vibration damping handle and a new user interface for choosing the work mode are included.
Good to know
- The listing gives no joule figure or concrete capacity, so check the maker's data sheet.
- Only the hammer and a case are listed, with no chisel or bit in the box.
Our take
Brushless motor
Bosch lists a brushless motor for superior machine reliability, with an automatic drive rotation system. Brushless designs avoid carbon brushes, which on corded SDS max hammers are a regular service item. The input power is given as 1,300 W.
The listing does not give impact energy or concrete capacity, so check Bosch's data sheet if you need those figures for a specification.
Three layers of protection
A safety clutch, KickBack Control and Vibration Control are listed together. The clutch slips mechanically when a bit jams. KickBack Control cuts the motor electronically if the tool starts to rotate suddenly. Vibration Control is supported by a vibration damping handle to reduce fatigue. On an SDS max hammer, where a jammed bit can twist the body hard, that combination is reassuring.
User interface and app
Bosch describes a new user interface, first in its class, for choosing the work mode, with app connectivity. That makes switching between drilling and chiselling clearer than a mechanical selector, and the app link can help with settings and tool management on larger sites.
Weight and contents
The listed weight is 8.5 kg. That places it between the HiKOKI DH40MC at 7.1 kg and the DH45MA at 9.4 kg. Only the hammer and a case are listed, so budget for bits and chisels.
At this weight, the tool is best used on floors, walls at waist height and from a stable platform. For overhead anchors, a lighter SDS plus hammer may be more practical even if each hole takes longer.
Who it suits best
Contractors who put safety features and electronic control first will find the GBH 6-42 C appealing. Buyers who want stated joule figures and capacity can compare the HiKOKI DH45MA with 11.3 J and 45 mm, or the Makita HR4013C with AVT and 40 mm.
Verdict
Choose the GBH 6-42 C if you want a brushless SDS max hammer with mechanical and electronic kickback protection and a modern mode selector. If you need published impact energy and capacity, the HiKOKI DH45MA and Makita HR4013C document theirs more clearly, and the HiKOKI DH40MC is a lighter alternative.
