What does the 4-mode designation mean on the SDS-Plus hammer?
The 4-mode designation on the 1-Inch Cordless SDS-Plus Rotary Hammer indicates that the tool offers four distinct operating configurations. These typically include rotation-only, hammer-only, rotary hammer, and Vario-Lock modes. Vario-Lock allows you to rotate the chisel bit to an optimal angle for demolition or chipping tasks, while the other modes allow you to switch between drilling, hammering, or a combination of both to suit the specific material and bit type you are using.
Is BiTurbo technology available on all Bosch cordless rotary hammers?
No, BiTurbo technology is specific to the high-performance PROFACTOR line, such as the GBH18V-36CK24-RT. This technology is engineered to deliver corded-like power in a cordless format by optimizing the synergy between the brushless motor and high-output batteries.
