A paint cutting tool is used to cut through thick layers of old paint, plaster or linoleum. The tool can be used to make holes where electrical wires need to be run or to cut holes in the ceiling or walls to install speaker wire. The tool is essentially a sharp metal cone attached to a handle. To use the tool, you lower the handle and rest it on the upper surface of the material. Then, you squeeze the handle until the cone pierces the material and lets out a high-pitched screech, similar to the sound of a drill. The tool is operated by hand or with the help of an electric drill. It takes practice to use the tool, but it is a very useful and versatile tool that can save you a lot of time and effort if you have to do a lot of drywall or ceiling work.
