Kickback control is the reason the Bosch GBH2-28L is our top pick. A rotary hammer can twist hard when a bit binds in rebar or old concrete, and this Bosch uses an integrated sensor to stop rotation before that kick reaches your wrists. That safety net sits alongside 2.4 ft-lbs of impact energy from an 8.5-amp motor and a 1-1/8-inch SDS-plus capacity, so it is not a compromise pick: it has the power for anchor holes and the control for tile and light chipping.
We also appreciate how manageable it feels for a corded hammer. At 2.9 kg (about 6.4 pounds), it is easy to hold overhead, and the handle gives you a solid place to push without fighting the tool. The three modes cover drilling, hammer drilling, and chipping, and Vario-Lock lets you index a chisel to the angle you need. Counter-balanced vibration control is not a luxury on a tool you use for a whole afternoon; it is the difference between finishing the row and stopping to shake out your hands.
The cord is the obvious trade. You get continuous power and no battery platform to buy into, but you also get a tether and a need for an outlet or a heavy extension cord. The Vario-Lock indexing is the detail we keep coming back to: it lets you set a chisel angle and work in hammer-only mode without fighting the tool around.
Bottom line: For most concrete drilling and light chipping, the GBH2-28L is the corded rotary hammer we recommend: strong, controlled, and easier to handle than its size suggests.
