The universal GBH 2-24 F Professional and GBH 2-26 F Professional 830 W machine with enlarged drilling diameter in concrete 26 mm has become even more efficient. Choice between a model with a fixed chuck and a model with an interchangeable chuck F , which additionally features a quick-action keyless chuck for ball-headed drills.

More control thanks to KickBack Control and vibration damping
The GBH 2-28 F Professional and GBH 2-28 Professional are the first power hammers in their power class which are equipped with KickBack Control. It ensures better control even with difficult drilling tasks. If the power tool rotates around its axis suddenly and unexpectedly – for example, if the drill bit misaligns during drilling in reinforced concrete – the integrated sensor switches the motor off in a fraction of a second. This prevents kickback and therefore reduces the risk of injury.
KickBack Control is indicated by the corresponding logo on the metal shroud. Both models also feature active vibration damping: A balancing weight mounted in the gearbox housing continuously counteracts the mass and aerodynamic forces generated by the hammer mechanism, thus reducing the vibration level to 11 m/s2. The result is safe, comfortable and precise work.
In addition, all four models include proven features such as continuously variable speed control for accurate drilling, a swivel brush holder for even pressure left and right, a rotation stop for chiseling mode, an SDS-plus chuck, and a swivel cable attachment to prevent cable breakage.
