Bosch RH328VC Corded 1-1/8″ 3-Mode Variable Speed SDS-Plus Rotary Hammer, 120V 8A

The Bosch RH328VC is a corded 1-1/8 in. SDS-plus rotary hammer with an 8 amp motor, 2.4 ft.-lbs. of impact energy, and three operating modes for drilling, hammer drilling, and chiseling. Built for concrete drilling, light demolition, and anchor work, this variable-speed rotary hammer includes an auxiliary handle, depth gauge, and carrying case for jobsite-ready use.

The Bosch RH328VC is built for users who need a compact SDS-plus rotary hammer with strong drilling and chiseling performance for concrete and masonry work. Its 8 amp motor delivers up to 2.4 ft.-lbs. of EPTA impact energy, up to 4,000 blows per minute, and up to 900 no-load RPM. That combination gives it the output needed for anchor holes, general concrete drilling, and light demolition tasks while keeping tool weight to 7.7 lb and overall length to 12.5 in. for a strong power-to-size ratio.

Bosch designed this rotary hammer with three operating modes: rotary hammer, rotation-only, and hammer-only. The tool also includes Vibration Control in the hammer mechanism and grip area to help reduce user fatigue, an integral clutch to disengage torque transmission in a bind, and Vario-Lock to position the chisel in one of 12 positions for better working angles. These features make it a practical choice for contractors, maintenance teams, and concrete trades that need one SDS-plus hammer for drilling and chipping work.

Why Customers Choose the Bosch Corded 1-1/8″ 3-Mode Variable Speed SDS-Plus Rotary Hammer

Customers choose the Bosch RH328VC because it gives them true SDS-plus rotary hammer performance in a compact corded tool that still feels manageable on repeated drilling and chipping jobs. For buyers working in concrete, block, or masonry, a standard hammer drill often does not provide the drilling speed or chiseling capability needed for daily trade work. The RH328VC fills that gap with three operating modes, solid impact energy, and the ability to handle both holes and light demolition tasks in one tool.

It also appeals to users who care about comfort and control. Vibration Control, a variable-speed trigger, Vario-Lock, and an integral clutch help make the tool easier to use over longer periods and across changing job conditions. For crews looking for a Bosch SDS-plus rotary hammer, concrete drill, or demolition hammer in a compact 1-1/8 in. class, the RH328VC remains a dependable option.
