Abstract: Control method for a dust extraction module (2) for a chiseling tool (5), including the following steps: using a fan (18) of the dust extraction module (2) to draw in an air flow Q from a certain place of a substrate (31) being worked by the tool (5), using a material detector (24) to identify the material M at the place of the substrate being worked by the tool (5), and adapting the suction power of the dust extraction module (2) 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 M1, whereas the air flow Q is less than the rated value Qo in the case of a material M2 containing iron.

Abstract: 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.
