Electrician’s chisels may be used by electricians in order to clear out spaces from walls when installing pattress boxes.
Normally, the angle on an electrician’s chisel is duller than on a flooring chisel.
Sometimes they may be called electrician’s bolsters.
What are pattress boxes?
Pattress boxes are the boxes behind electrical sockets where wiring is kept in order to protect it from damage. Some of these boxes sit on the wall, whilst others are actually set into the wall.
How to use a chisel in the installation of a pattress box:
Step 1 – Drill series of holes
When installing a pattress box, the user drills into the area where the box will sit.
Step 2 – Remove remainder with chisel
Then the remaining debris can be chiseled away until the space is empty.
The type of chisel you use may depend on what material you are trying to chisel through.
