Mini saw nozzle

Prefix mini file

— an accessory used primarily for engravers and other similar hand tools of small size and power. As the name suggests, this bit is a miniature circular saw, usually with a protective sheath. It is very handy when sawing laminate and other thin materials: the mini file provides a much more precise and accurate cut than a full-size saw or even a jigsaw. In addition, buying such a nozzle is much cheaper than purchasing the same jigsaw, and it takes up less space.
