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 Core 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-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.

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.

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.

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 allows you to choose from 12 chisel positions to match the angle of many surfaces.

RH1255VC model provides smooth starts and won't slow down as you drill deeper.

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.
