Chasing chisels are sometimes used to cut channels so that cables and wires can be placed in walls. They have a somewhat wider cutting edge than a flat chisel.
They are known as “chasing” chisels due to the fact that these channels are called “chases”. The process of cutting into these walls is known as “wall chasing”.
How to cut channels in walls with a chasing chisel:
Step 1 – Mark channel
Mark the channel you will be cutting out.
Step 2 – Use chisel
Chisel out the channel.
Its depth should account for the fact that the wall will need replastering after the cables and plastic conduit have been installed.
Depending on what material you are chiselling, different chisels may be more appropriate.
