Abstract

A control method for a borehole flushing module (2) for a chiseling tool (5), includes the steps: Providing fine-grain particles in a dispenser (31); ascertaining a material (M) at a location processed by the tool (5) with the aid of a material detector (37); and introducing fine-grain particles at the location of the substrate processed by the tool (5) when the material detector (37) ascertains an iron-containing material (M2).
