Operating modes

— Drilling with impact. A mode of operation that combines rotation and percussive movement of the drill. Due to this, a complex effect on the treated surface is provided; in this case, the impact gives a direct advancement of the drill, and rotation is used primarily to remove the resulting waste. It is this format of work that allows you to effectively make holes in materials like concrete, brick, natural stone, etc .; at the same time, rotary hammers cope with such tasks much more efficiently than the so-called impact drills (drills supplemented with a chiseling function).

Drilling (without impact). Traditional drilling, when the hammer works like a drill: the working equipment only rotates, not moving back and forth. It is applied to work with rather soft materials, such as a tree and metal. At the same time, rotary hammers are often more efficient than traditional drills — due to the greater power and weight of the tool, they allow you to drill larger and deeper holes with sufficient accuracy.

Chiseling (demolition hammer). In this mode, the punch tool only moves back and forth, without rotation. This format of work can be useful when splitting large pieces of hard material, removing various coatings, etc. We emphasize that a rotary hammer, even a powerful and heavy one, will not replace a full-fledged demolition hammer; however, for relatively simple tasks — such as dismantling smal...l structures made of relatively soft materials, splitting tiles, chasing walls, etc. — a tool with this mode is quite suitable.

Power cord length

Power cord length for mains powered drills (see above). The longer the cord, the farther from the outlet you can use the unit and the less it depends on the location of the outlets.
