What’s the difference between a Rotary Pneumatic Hammer drill and a standard impact hammer drill?
Heavier duty models known as Rotary Pneumatic Hammer drills are far more efficient over the standard impact action. It’s like comparing a mash hammer vs. a sledge hammer! These tools are generally used by professionals or those who perform regular heavy duty drilling into masonry and concrete. They are generally around 3 times faster than conventional hammer drills. They are constructed using an internal pneumatic (air) cylinder that is very effective in a hammer action, in fact around 3 times more efficient over standard impact hammer drills.
