Hammer Drills vs. Rotary Hammers (SDS)

Why does an electro-pneumatic Rotary Hammer (SDS) drill concrete vastly faster than a mechanical hammer drill?

 Correct IncorrectRotary hammers use an internal air-cushioned piston that strikes a striker pin directly against the bit shank, delivering huge impact energy (Joules) rather than buzzing mechanical ratchet discs.

Why does an electro-pneumatic Rotary Hammer (SDS) drill concrete vastly faster than a mechanical hammer drill?

• It spins three times faster than a regular drill
• It uses diamond water suction to dissolve limestone
• It heats the concrete until it melts with laser beams
• An electro-pneumatic piston delivers high impact energy (Joules) directly to the bit
