Appliances and tool that only have two pin caps (plugs) are built so that they have double insulation. This means that the electrical "hot" parts can not be touched by handling the appliance or tools and the outside shell is completely insulated and isolated from the inside shell of the equipment. Equipment that require a three pin cap (plug) do not have the double insulation and isolation built into the equipment so protection from getting an electrical shock is done by grounding the equipment, that is what the third pin is. It is used strictly for grounding.

Why do some electrical plugs only have two pins?

In many cases, devices with two-pin plugs are double-insulated and don't require grounding. This design is common for low-power electronics and appliances that do not pose a high risk of electric shock. The two pins provide enough power for these devices to function safely.

Is it okay to use an adapter to change a three pin plug into a two pin plug?

No, it is not ok, it is potentially very dangerous because the two-wire cable has no earth with it. The earth wire is an important safety component that comes with a three-pin plug. An exception can be made for certain low-power appliances that have double insulation. This includes TV sets, radios, and table lights provided the mounting is plastic and not metal. These appliances are commonly sold with a twin-wire cable but often with a three-pin plug on the end of it. The three-pin plug in this case often has a plastic 'earth' pin and it is safe to replace it with a two-pin plug.
