4 Reasons to Never Use a Cheater Plug on an Old Power Tool

You remove the only safety path Older power tools have metal bodies and no double insulation. The third prong grounds the tool, so if a wire comes loose, the current goes to the breaker instead of through you. A cheater plug kills that path, making you the ground.

You risk electrocution from a short If the tool shorts, the metal case becomes live. Without a ground, that current flows into your hand. You will feel it.

Extension cords make it worse Long cords add resistance and voltage drop. Adding a cheater plug creates an ungrounded, underpowered setup. Many two-prong adapters rely on the outlet’s center screw, which often isn’t actually grounded.

There are safer alternatives Use a grounded three-prong extension cord or replace the tool’s plug with a modern one. If your outlet only has two slots, have an electrician install a GFCI instead.
