Mini wire rolling mill functions similar to a small rolling mill. This tool is used to shape wire for making and for stretching ring bands. 
 
This tool is like the small rolling mill but designed for only light rolling of wire and strips of soft metal.
 
The main roller can be used to shape wire and strips of metal into half-round ring bands between 1.6 and 4 mm. The interchangeable side roller can be used to stretch rings between 1.4 and 3.5 mm, sizes 4.5 and up. The side roller also comes with a flat die for stretch flat-banded rings. 
 
This mill comes with 3 design rollers and to change them you will have to use an alan key to open the nut on the end of the roller. Once swapped place washer and bolt back on and re-tighten. Please note - alan key is not included.
 
This mini ring roller is about 9 inches tall. The base measures 5.5" x 2.5" and has holes so that it can be mounted securely to a table or bench if you wish.
