All of these bits may be used in a hand tool, but we suggest using the Dremel Mini-Mite tool because your project can be completed in a fraction of the time and with much more ease than when using a hand tool. We suggest you start by practicing on a scrap piece of glazed ceramic. Practice etching some lines and circles until you feel comfortable with it. When etching, the object is to just scratch the surface. You do not want to break through the glazed surface.
Light etching produces a more elegant finished piece.
An easy way to judge the amount of pressure to use is to feel the etched surface. You should be able to feel the etched line when scratching across it with your finger nail, but you should only be able to feel the etched line slightly with the skin of your finger. Use light hand pressure, as the motor tool will do the work for you. When etching long or curved lines and circles, it is best to etch away from yourself because you are working with the rotation of the bit and will achieve a much smoother line than if you are working against the rotation of the bit. Etch all traced lines of the design using the medium diamond ball.
