Bosch RH850VC Corded 1-7/8″ 2-Mode Variable Speed SDS-Max Rotary Hammer, 120V 15.4A

The Bosch RH850VC is a corded 1-7/8 in. SDS-max combination hammer with a 14.5 amp motor, 9.3 ft.-lbs. of EPTA impact energy, and two operating modes for rotary hammer drilling and hammer-only chiseling. Built for concrete drilling, demolition, and heavy remodeling work, this variable-speed Bosch hammer includes an auxiliary handle, grease tube, and carrying case for jobsite-ready use.

The Bosch RH850VC is built for users who need heavy-duty SDS-max drilling and chiseling performance without stepping up to a larger 2 in. class hammer. Its 14.5 amp motor delivers 9.3 ft.-lbs. of EPTA impact energy, with a no-load speed range of 150 to 305 RPM and a blow rate of 1,380 to 2,750 BPM. That output makes it well suited for larger anchor holes, concrete drilling, and hammer-only demolition tasks where strong corded performance and repeatable impact energy matter.

This combination hammer uses a two-mode setup with rotary hammer and hammer-only operation, along with a variable-speed dial for more controlled drilling and chipping. It also includes Bosch Vibration Control, Constant Response circuitry, an electro-pneumatic impact system, an integral clutch, and Turbo Power in hammer-only mode. The SDS-max bit system allows tool-free bit changes, and the padded rear handle plus auxiliary handle help improve user comfort during demanding work.
