Bosch GBH18V-26 Cordless Rotary Hammer Review

The Bosch GBH18V-26 isn’t just any cordless rotary hammer. The rotary hammer is the workhorse of any construction site, providing the power and torque to drill and chisel in concrete and masonry materials. But the real differentiator among these power tools is putting all of that performance in a package that delivers great power at low weight – and that’s the story of the Bosch GBH18V-26 1″ SDS-plus® EC brushless rotary hammer.


This Bosch rotary hammer delivers 1.9 Ft.-Lbs. of torque in a tool that weighs only 7.7 lbs. The ergonomic L-shape design offers great horizontal power transmission. Combined with a Bosch 6.0 Ah 18V lithium-ion battery, this is a power tool that will drill longer and hit harder than bigger tools with more weight.
