Control method for a dust extraction module () for a chiseling tool (), including the following steps: using a fan () of the dust extraction module () to draw in an air flow Q from a certain place of a substrate () being worked by the tool (), using a material detector () to identify the material M at the place of the substrate being worked by the tool (), and adapting the suction power of the dust extraction module () as a function of the identified material M in order to set the air flow Q. The air flow Q is greater than or equal to a rated value Qo in the case of an iron-free mineral material M, whereas the air flow Q is less than the rated value Qo in the case of a material Mcontaining iron.

A control method for a bore-chiseling portable power tool for machining a substrate by a drill bit includes superimposing a periodic striking on the drill bit at an impact rate and a rotating of the tool holder at a rotational speed in a rotational direction, identifying a material of the substrate being machined by the drill bit by a sensor, adjusting the rotational speed and/or the rotational direction to a first rotational speed and a first rotational direction when the identified material is an iron-based material, and adjusting the rotational speed and/or the rotational direction to a second rotational speed and a second rotational direction when the identified material is a mineral material. The first rotational speed is less than the second rotational speed and the first rotational direction is counter-clockwise and the second rotational direction is clockwise.
