Bosch RH540M Drills | McMaster-Carr

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 drill rotates.

For SDS-Max Bit Shanks—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.

12 Chisel Lock Positions—A chisel lock allows you to choose from 12 or 36 chisel positions to match the angle of many surfaces.

Built-In Safety Clutch—A built-in safety clutch protects you and the hammer if the bit gets stuck in your material.
