Impact drill


Taladradora de percusión

Perceuse à percussion

An impact drill is a power tool designed for drilling in concrete, stone and similarly hard materials. The impact drill has a built-in ratchet-controlled impact mechanism to generate a linear percussive motion which is superimposed on the rotation of the drive shaft. The impact force increases with the applied operator pressure. The maximum impact rate can reach up to 48 000 individual impacts per minute. If the impact mechanism can be switched off, the machine can be used like a standard drill. It is commonly designed for clockwise rotation and for one or more speeds and/or electronic speed regulation. If equipped with a switch to reverse the running direction and electronic speed regulation, impact drills can also be used for screwdriving if necessary if the impact mechanism is turned off.
