Flooring chisels are frequently used when breaking and lifting up floorboards. They are usually somewhat longer than other chisels, and the cutting edge of the chisel is designed to slice through the tongue section of tongue and groove flooring and subsequently help to lift the board up.
Flooring chisels may sometimes be known as “electricians’ (flooring) chisels” or “electricians’ bolsters”.
It should be noted that there may be an overlap between flooring chisels and electricians’ chisels, although traditionally the angle on a flooring chisel is sharper.
Sometimes a slightly different design may be employed, such as this curved section designed to assist with gaining leverage on the floorboard.
What are tongue and groove floorboards?
Tongue and groove floorboards (such as the one shown to the left) are a type of floorboard designed with a raised section along one side and a recessed groove along the other.
The raised section slots into the recessed groove on an adjoining floorboard.
How to use a flooring chisel to raise floorboards:
Step 1 – Break tongue
Should the user wish to raise tongue and groove floorboards, the tongue must be broken in order to release them.
Before removing the flooring, it is important to remove any skirting board, as this will get in the way.
Step 2 – Lift floorboard
The floorboard can then be lifted up using the chisel.
