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.

Spline-Drive Bosch Electric Rotary Hammers
Designed to drill larger holes than a SDS-drive hammer, this model uses spline-shank drill bits (see Spline-Shank Masonry Drill Bits and Spline-Shank Masonry Drill Bits). A powerful and durable hammer mechanism lets you drill deeper, larger holes in masonry and concrete in less time than with hammer drills.
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).
This rotary hammer has a vibration reduction system for increased user comfort, provides smooth starts, and won't slow down as you drill deeper. It also has a variable speed motor—the further you depress the trigger, the faster the speed. A built-in safety clutch protects you and the hammer if the bit gets stuck in your material. A chisel lock allows you to choose from 12 chisel positions to match the angle of many surfaces.

SDS-Max-Drive Bosch Electric Rotary Hammers
A deeper drive system minimizes wobble for straighter, more accurate holes and better overall performance to other rotary hammers. 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-Max drill bits (see SDS-Max-Shank Masonry Drill Bits and SDS-Max-Shank Core 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.

Bosch Electric Hammer Drills
Just push a switch and this tool will change from a standard electric drill to a hammer drill.
The rotary-only mode is for general purpose drilling and driving fasteners. Use this mode with standard drill bits for wood and metal. In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. The hammering action pounds concrete and masonry, which breaks up the material while it drills. Use this mode for drilling masonry materials using carbide-tipped masonry drill bits.
This drill has a keyed chuck that can be tightened with the included key. It also has a variable speed—the further you depress the trigger, the faster the drill rotates.
