Chiselling like a master craftsman
Expert DIYers also have a few tricks up their sleeve for simple work like chiselling. We will tell you what they are.
Chisels loosen and destroy the structure of stone by means of an impact and wedge effect. The shape and quality of the work result are heavily dependent on using the right chisel. There are various chisel shapes for different materials and purposes, e.g. flat, spade or tile chisels for knocking off tiles, gouging chisels for cutting cable ducts and channels for pipes, cross chisels for cutting out slots and parting chisels for breaking through pre-drilled plates.
Important: Please always wear protective glasses when chiselling because splintering parts can easily get into your eyes.
Pilot chiselling: First of all, you have to strike a guide groove. To do this, hold the chisel at a slight angle and make the guide groove approximately one centimetre deep by means of light hammer blows. This scores the material.
Breakthrough chiselling: Now hold the chisel in an upright position and guide the hammer into the guide groove, in order to break off the workpieces.
Pay attention to the following when you clamp workpieces for chiselling: The chisel direction must always point against the vice jaws.
A Bosch rotary hammer makes it particularly easy for you: You can use it to prise open small wall breaks, cut cable slots or chisel off tiles. Make sure you switch off the rotary motion of the Bosch rotary hammer. You only need the impact function for chiselling.
