Bosch RH745 Corded 1-3/4″ 2-Mode Variable Speed SDS-Max Rotary Hammer, 120V 13.5A

The Bosch RH745 is a corded 1-3/4 in. SDS-max rotary hammer with a 13.5 amp motor, 8.2 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 rotary hammer includes an auxiliary handle, grease tube, and carrying case for jobsite-ready use.

The Bosch RH745 is built for users who need heavy-duty SDS-max drilling and chiseling performance in a corded rotary hammer. Its 13.5 amp motor delivers 8.2 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 consistent corded power matters. At 18.5 lb, it is positioned for demanding trade use while still remaining manageable for repeated drilling and chipping applications.

This rotary hammer uses a two-mode setup with rotary hammer and hammer-only operation, along with a variable-speed dial for more controlled drilling and chiseling. The Vario-Lock function lets the user rotate and lock the chisel into 12 positions to improve the working angle in hammer-only mode. Bosch also equips the tool with an SDS-max bit system for tool-free bit changes, a Service Minder light for preventative maintenance awareness, and a soft-grip rear handle plus 360° auxiliary handle for better comfort and control.

Why Customers Choose the Bosch Corded 1-3/4″ 2-Mode Variable Speed SDS-Max Rotary Hammer

Customers choose the Bosch RH745 because it gives them heavy-duty SDS-max drilling and chiseling performance in a tool designed for serious concrete and demolition work. For jobs that require larger holes, repeated chipping, or more aggressive concrete drilling, lighter rotary hammers may not offer the necessary impact energy or capacity. The RH745 fills that gap with strong output, two operating modes, and a setup geared toward demanding commercial use.

It also appeals to users who want more control and service visibility on the job. The variable-speed dial, Vario-Lock function, tool-free SDS-max bit changes, and Service Minder light all support more efficient daily use. For buyers looking for a Bosch concrete hammer, rotary hammer, or demolition-ready SDS-max tool in the 1-3/4 in. class, the RH745 remains a solid option for construction and renovation work.
