SDS-Drive Bosch Electric Rotary Hammers
Also known as SDS-Plus rotary hammers, these are lightweight and ideal for overhead work and drilling smaller holes. A powerful and durable hammer mechanism lets you drill deeper, larger holes in masonry and concrete in less time than with hammer drills. Use with SDS-Plus drill bits. Note: SDS-Plus and SDS-Max bits are not interchangeable.
Use the rotary-only mode for general purpose drilling and driving fasteners (requires a chuck adapter or a magnetic bit holder). In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. In the percussion-only mode, the tool provides only the hammering action. Use this mode when working with chisels and other masonry tools (see Chisels for Rotary Hammers).
All have a variable speed motor—the further you depress the trigger, the faster the speed. They also have a built-in safety clutch to protect you and the hammer if the bit gets stuck in your material. A chisel lock feature allows you to choose from 36 chisel positions to match the angle of many surfaces.
